Leveraging ChatGPT to Generate RDL Output for Paginated Report Files

Introduction

Report Definition Language (RDL) is an XML language that provides a robust, standardized format for defining reports. It’s commonly utilized in conjunction with SQL Server Reporting Services (SSRS), which allows you to create, deploy, and manage reports for your organization.

This blog post is aimed at guiding you on how to leverage the power of ChatGPT, a state-of-the-art AI developed by OpenAI, to assist in generating XML output for RDL files. The beauty of this approach is that the AI can generate the necessary XML code based on your inputs, which you can then copy and paste into an .rdl file, creating a functional report almost instantaneously.

Step-by-Step Guide to Create an RDL File with ChatGPT Assistance

Step 1: Defining the Objective of Your Report

Start by clearly stating the goal of your report. This will help ChatGPT understand the type of data that needs to be included and how it should be structured.

User: I need to create a report that shows the sales revenue by product category for the current year.

ChatGPT: Sure, for such a report you would need access to sales data including product details, sale dates, and revenue. Do you have a database where this information is stored?

Step 2: Defining the Data Source

Once you’ve clarified the objective of your report, the next step is defining the data source. This includes providing the type of database you’re using, server name, database name, and the necessary authentication details.

User: The data is stored in a SQL Server database named 'SalesDB' on the server 'Server01'. The authentication method is SQL Server Authentication.

ChatGPT: Great! Let's create the DataSource XML for your RDL file.

At this point, ChatGPT will generate the necessary DataSource XML.

ChatGPT:
```xml
<DataSources>
    <DataSource Name="SalesDB">
        <ConnectionProperties>
            <DataProvider>SQL</DataProvider>
            <ConnectString>Data Source=Server01;Initial Catalog=SalesDB;User ID=your_username;Password=your_password;</ConnectString>
        </ConnectionProperties>
    </DataSource>
</DataSources>

Step 3: Defining the Dataset

The Dataset comprises the SQL query that retrieves the desired data from the database.

```chat
User: The necessary data can be retrieved with the following SQL query: 'SELECT ProductCategory, SUM(Revenue) as TotalRevenue FROM Sales WHERE YEAR(SaleDate) = YEAR(GETDATE()) GROUP BY ProductCategory'.

ChatGPT: Great, let's use that query to define the Dataset in your RDL file.

ChatGPT then generates the corresponding Dataset XML.

ChatGPT:
```xml
<Datasets>
    <Dataset Name="SalesData">
        <Query>
            <DataSourceName>SalesDB</DataSourceName>
            <CommandText>
            <![CDATA[SELECT ProductCategory, SUM(Revenue) as TotalRevenue FROM Sales WHERE YEAR(SaleDate) = YEAR(GETDATE()) GROUP BY ProductCategory]]>
            </CommandText>
        </Query>
        <Fields>
            <Field Name="ProductCategory">
                <DataField>ProductCategory</DataField>
                <rd:TypeName>System.String</rd:TypeName>
            </Field>
            <Field Name="TotalRevenue">
                <DataField>TotalRevenue</DataField>
                <rd:TypeName>System.Decimal</rd:TypeName>
            </Field>
        </Fields>
    </Dataset>
</Datasets>

Step 4: Defining the Report Layout

The report layout defines how the retrieved data should be presented in the report. This typically involves specifying items such as tables, matrices, or charts.

```chat
User: I want to present the data in a simple table with two columns: one for the Product Category and one for the Total Revenue.

ChatGPT: Alright. Let's create the report layout XML for your table.

ChatGPT then generates the report layout XML based on your requirements.

ChatGPT:
```xml
<ReportItems>
    <Tablix Name="SalesTablix">
        <TablixBody>
            <TablixColumns>
                <TablixColumn>
                    <Width>3in</Width>
                </TablixColumn>
                <TablixColumn>
                    <Width>2in</Width>
                </TablixColumn>
            </TablixColumns>
            <TablixRows>
                <TablixRow>
                    <Height>0.25in</Height>
                    <TablixCells>
                        <TablixCell>
                            <CellContents>
                                <Textbox Name="ProductCategoryHeader">
                                    <Paragraphs>
                                        <Paragraph>
                                            <TextRuns>
                                                <TextRun>
                                                    <Value>Product Category</Value>

                                    </Paragraphs>
                                </Textbox>
                            </CellContents>

                            <CellContents>
                                <Textbox Name="TotalRevenue">

Step 5: Assembling the Full RDL File

At this point, you have all the necessary XML for your RDL file. You can put these pieces together into a full RDL file, ensuring that you include the necessary boilerplate XML for an RDL file. Don’t forget to adjust connection string information for your data source, where necessary.

Here it is as an example:

<?xml version="1.0" encoding="utf-8"?>
<Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">
    <DataSources>
        <DataSource Name="SalesDB">
            <ConnectionProperties>
                <DataProvider>SQL</DataProvider>
                <ConnectString>Data Source=Server01;Initial Catalog=SalesDB;User ID=your_username;Password=your_password;</ConnectString>
            </ConnectionProperties>
        </DataSource>
    </DataSources>
    <DataSets>
        <DataSet Name="SalesData">
            <Query>
                <DataSourceName>SalesDB</DataSourceName>
                <CommandText>
                <![CDATA[SELECT ProductCategory, SUM(Revenue) as TotalRevenue FROM Sales WHERE YEAR(SaleDate) = YEAR(GETDATE()) GROUP BY ProductCategory]]>
                </CommandText>
            </Query>
            <Fields>
                <Field Name="ProductCategory">
                    <DataField>ProductCategory</DataField>
                    <rd:TypeName>System.String</rd:TypeName>
                </Field>
                <Field Name="TotalRevenue">
                    <DataField>TotalRevenue</DataField>
                    <rd:TypeName>System.Decimal</rd:TypeName>
                </Field>
            </Fields>
        </DataSet>
    </DataSets>
    <ReportSections>
        <ReportSection>

                            <TablixColumns>
                                <TablixColumn>
                                    <Width>3in</Width>
                                </TablixColumn>
                                <TablixColumn>

                                        <TablixCell>
                                            <CellContents>
                                                <Textbox Name="ProductCategoryHeader">
                                                    <Paragraphs>

            </Body>
        </ReportSection>
    </ReportSections>
</Report>

The example provided here should be fully functional, but there are some considerations to keep in mind:

  1. Database Schema: The SQL query included in the report depends on your database schema. The given example assumes that there’s a table called ‘Sales’ with the columns ‘ProductCategory’, ‘Revenue’, and ‘SaleDate’. Make sure that your database contains this table and these columns or adjust the SQL query to match your actual database schema.
  2. Authentication: The example uses SQL Server Authentication for simplicity, but you might be using a different authentication method, such as Windows Authentication or Azure Active Directory. Make sure to adjust the connection string to match your actual authentication method.
  3. Report Design: The example includes a very basic report design that outputs a simple table. In a real-world scenario, your report might require additional elements, such as a header, footer, grouping, sorting, filtering, images, subreports, etc. RDL is very flexible and allows you to create complex report designs.
  4. Data Types: The provided XML assumes that ‘ProductCategory’ is a string and ‘TotalRevenue’ is a decimal. If your actual data types are different, make sure to adjust the <rd:TypeName> elements accordingly.
  5. Data Source Security: The provided example includes the username and password in the connection string for simplicity, but this isn’t secure. In a real-world scenario, you should consider more secure methods to store and retrieve your credentials, such as storing them in the Reporting Services Configuration Manager or using Integrated Security.
  6. Error Handling: While this isn’t strictly necessary for the RDL file to be functional, it’s a good idea to implement error handling in your reports, such as displaying a meaningful message if the SQL query returns no data.

As long as your report’s requirements align with what’s defined in this XML, you should be able to generate a functional report by replacing the placeholders with your actual values. However, this is a basic example and real-world reports can get much more complex. For more advanced features, you might need to manually edit the RDL file or use a tool like SQL Server Data Tools or Report Builder, which provide a GUI for designing reports.

Conclusion

Leveraging AI models like ChatGPT to generate RDL file content allows you to quickly and accurately create complex reports. By providing your specifications to the AI, you can obtain a ready-to-use XML output for your RDL file, reducing the time spent on manual coding and minimizing the potential for human error. Happy reporting!

Unveiling the Hidden Gems: Lesser-Known Features of Paginated Reports in Power BI and SSRS

Introduction

Paginated reports, commonly referred to as “pixel-perfect” reports, are an essential tool for creating data-rich, highly customizable, and print-ready reports. While many users are familiar with the basic features of paginated reports in Power BI and SQL Server Reporting Services (SSRS), there are several lesser-known capabilities that can enhance the overall reporting experience. In this blog post, we’ll explore some of these hidden gems and explain how they can add value to your paginated reports.

  1. Document Map

The Document Map feature allows you to create a navigable outline or table of contents for your paginated report, making it easier for users to quickly jump between different sections or categories within the report. By adding a Document Map, you can provide a more organized and user-friendly reporting experience, especially for lengthy and complex reports.

  1. Interactive Sorting

Interactive Sorting enables users to sort data in a table or matrix directly within the report by clicking on column headers. This powerful feature provides users with more control and flexibility to explore and analyze the data according to their needs. To enable interactive sorting, simply set the “InteractiveSort” property of the table or matrix column header textbox.

  1. Custom Code and Expressions

Paginated reports support custom code and expressions, allowing you to create complex calculations, data transformations, or conditional formatting rules that might not be achievable with built-in functions. You can use Visual Basic.NET (VB.NET) to write custom code within the report, and then reference the custom functions in your report expressions.

  1. Fixed Headers and Footers

When dealing with long tables or matrices that span multiple pages, it can be helpful to keep the headers and footers visible as users scroll or navigate through the report. To achieve this, simply set the “FixedData” property of the table or matrix header row to “True.” This ensures that the headers and footers remain in place, providing users with essential context as they explore the data.

  1. Data-Driven Subscriptions

Data-driven subscriptions enable you to automate the delivery of paginated reports based on dynamic, data-driven criteria. This feature, available only in SSRS, allows you to configure report delivery based on data stored in an external data source, such as a database table or a query result. Data-driven subscriptions can be used to deliver personalized reports to users or to schedule report delivery based on specific conditions or events.

  1. Custom Pagination

By default, paginated reports use automatic pagination to determine the number of pages and the layout of report items. However, you can also take full control over the pagination process by using custom pagination. This allows you to specify the exact number of rows or columns to display per page and to control the placement of report items across multiple pages.

Conclusion

While many users are familiar with the basic features of paginated reports in Power BI and SSRS, exploring lesser-known capabilities can provide a more powerful, flexible, and user-friendly reporting experience. By leveraging features such as Document Maps, Interactive Sorting, Custom Code and Expressions, Fixed Headers and Footers, Data-Driven Subscriptions, and Custom Pagination, you can create truly dynamic and interactive reports that cater to a wide range of user needs and preferences.

using OpenAI;

public static class OpenAIIntegrationFunction
{
    [FunctionName("OpenAIIntegrationFunction")]
    public static async Task<IActionResult> Run(
        [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
        ILogger log)
    {
        log.LogInformation("C# HTTP trigger function processed a request.");

        // Get the 'prompt' parameter from the query string
        string prompt = req.Query["prompt"];

        // Use OpenAI API Key
        string openaiApiKey = Environment.GetEnvironmentVariable("OPENAI_API_KEY");

        // Initialize the OpenAI API client

        // Set up the completion request
        var completions = await apiClient.Completions.CreateAsync(
            engine: "text-davinci-002",
            new CompletionRequest
            {
                Prompt = prompt,
                MaxTokens = 50,
                N = 1,
                Stop = null,
                Temperature = 0.7,
            }
        );

        string generated_text = completions.Choices[0].Text.Trim();

        // Replace with your SQL Server connection string
        string connectionString = "your_sql_server_connection_string";

        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            connection.Open();
            using (SqlCommand command = new SqlCommand("INSERT INTO OpenAI_Responses (Prompt, GeneratedText, DateGenerated) VALUES (@Prompt, @GeneratedText, @DateGenerated)", connection))
            {
                command.Parameters.AddWithValue("@Prompt", prompt);
                command.Parameters.AddWithValue("@GeneratedText", generated_text);
                command.Parameters.AddWithValue("@DateGenerated", DateTime.UtcNow);

                await command.ExecuteNonQueryAsync();
            }
        }

        return new OkObjectResult("Data saved to the database.");
    }
}

Copy and paste this code into your Azure Function App. Replace the your_sql_server_connection_string placeholder with your actual SQL Server connection string. This code assumes you have already set up an OpenAI API key as an environment variable within your Azure Function App.

  1. Save the function and test it to ensure it inserts the AI-generated content into the SQL Server table.

Step 3: Create a Power BI Paginated Report

  1. Open Power BI Report Builder.

  3. Add a new “Parameter” to the report:
    • In the “Report Data” pane, right-click “Parameters” and click “Add Parameter.”
    • Name the parameter “Prompt.”
    • Set the data type to “Text.”
    • Provide a default value or leave it blank.
  4. Add a “Textbox” to the report and set its value to the “Prompt” parameter: =Parameters!Prompt.Value

Step 4: Connect the Power BI Paginated Report to the SQL Server database

  1. In the “Report Data” pane, right-click “Data Sources” and click “Add Data Source.”
  2. Choose “Microsoft SQL Server” as the connection type and provide a name for the data source.
  3. In the “Connection string” field, enter your SQL Server connection string.
  4. Click “OK” to add the data source.
  5. In the “Report Data” pane, right-click “Datasets” and click “Add Dataset.”
  6. Choose the SQL Server data source you just created and click “Query Designer.”
  7. In the “Query Designer,” enter a SQL query to fetch the latest AI-generated content for the given prompt:
SELECT TOP 1 GeneratedText
FROM OpenAI_Responses
WHERE Prompt = @Prompt
ORDER BY DateGenerated DESC

8. Add the “Prompt” parameter to the query by clicking

“Add Parameter” in the “Query Designer.” 9. Close the “Query Designer” and click “OK” to add the dataset.

  1. Add a “Textbox” to the report and set its value to the AI-generated text: =First(Fields!GeneratedText.Value, "Dataset1")

Conclusion: You now have a Power BI Paginated Report that displays AI-generated content based on the prompt parameter. When the report is run, it will retrieve the latest AI-generated content for the given prompt from the SQL Server database and display it in the report. To update the AI-generated content in the SQL Server database, you can manually call the Azure Function with the specified prompt, or you can create a separate application to automate this process. The Azure Function will then call the OpenAI API, generate the text, and insert it into the SQL Server table.

This approach allows you to leverage the Power BI Paginated Report’s native support for SQL Server as a data source while still incorporating AI-generated content from the OpenAI API. It involves additional steps and requires an intermediary database, but it provides a viable solution for integrating OpenAI with Power BI Paginated Reports

  1. Set up data sources and datasets

Once you’ve opened Power BI Report Builder, you’ll need to set up data sources and datasets. To do this, go to the “Report Data” window, right-click “Data Sources,” and click “Add Data Source.” After connecting to your data source, create a dataset by right-clicking “Datasets” and selecting “Add Dataset.” This process will allow you to access the data in your report.

  1. Use tables, matrices, and lists wisely

Paginated reports offer a variety of data regions, including tables, matrices, and lists. Each data region has its own unique capabilities:

  • Tables: Use tables for displaying data in a simple row and column format.
  • Matrices: Use matrices to show aggregate data, especially when you need to display row and column groupings.
  • Lists: Use lists to create free-form reports with varying data layouts.

Choose the appropriate data region based on your report’s requirements to ensure an efficient and organized layout.

  1. Leverage expressions for dynamic content

Expressions are a powerful way to create dynamic content in your paginated reports. You can use expressions to:

  • Concatenate fields
  • Format dates and numbers
  • Calculate totals and averages
  • Implement conditional formatting

Learn the basics of expression syntax and familiarize yourself with the available functions to unlock the full potential of your paginated reports.

  1. Utilize headers and footers

Headers and footers are essential for adding context and professionalism to your reports. Use them to display important information such as page numbers, report titles, and company logos. Headers and footers can also contain dynamic content using expressions, making them even more versatile.

  1. Manage page breaks and pagination

Controlling page breaks and pagination is crucial for ensuring a clean and well-organized report. Use the “Page Break” property in the properties window to control the placement of page breaks within your report. Additionally, you can use the “PrintOnFirstPage” and “PrintOnLastPage” properties to control the visibility of report items on the first and last pages.

  1. Preview and test your report

Always preview and test your report to ensure that it meets your requirements and displays correctly. This will help you identify any issues or discrepancies early in the design process, saving you time and effort in the long run.

Happy birthday, Paginated Report Bear!

Paginated Report Bear turns 1 year old today.  He wasn’t expected to last more than a few weeks.

20190405_043319215_iOS

For those of you who aren’t familiar with Paginated Report Bear, my friend Chris Webb described him as follows – “Well, he’s the breakout social media star of 2019, a furry YouTube sensation whose incisive interviews of members of the Power BI development team have become renowned for their deep technical content and insights into the Power BI roadmap. If you’re not watching his videos on YouTube, you’re missing out.”

If you watch the very first video that “Padgie” did 1 year ago today, Chris’s description seems EXTREMELY generous.  The production quality was very low, and Mr. Matthew (my son) couldn’t even say “Paginated Reports”.  Why even do videos with a bear in the first place?  You see, my son had for some time wanted to do a YouTube video series with me where his stuffed animals would be included.  They had been granted various personalities and voices throughout the years by yours truly, and these characteristics have carried over to the videos.  I decided to rename “Mickey” to “Paginated Report Bear” because he was the lovable but dumb one, and I thought the name sounded ridiculous.  And since my (naïve) assumption was we’d do a few of these videos during my vacation, and my son would get tired of doing them, that would be that.  And that almost happened – there wasn’t any videos for a month from December to January, and I figured that was the end of it.

Then something strange happened – not only did my son want to do more, but some members of the Power BI community seemed to actually ENJOY the videos.  He was featured on Guy in a Cube, he was mentioned on the BiFocal podcast, and he was a hit at the MVP Conference in March (he even got an MVP pin!).  It was then that we decided to have him start interviewing members of the product team, starting with Lukasz back in April, and the rest is history.

But the biggest achievement of Paginated Report Bear is the one he’s taught my kids as they’ve watched their dad carry a cheap stuffed bear purchased from EBay to conferences across the country just so people can take a selfie with him – you can do something different, or be different, and be successful in your career and in life.  That means a lot, and shows the broad Power BI community can have an impact outside of the day to day product details.

So thank you, and I look forward to what the future has in store for Paginated Report Bear in the year ahead!

Free sample Power BI paginated report – Ultimate Export Report available for download

I recently came across an interesting article on MSSQLTips for SQL Server Reporting Services that showed how you could use a T-SQL query as the parameter value, and have it return a table of data as the result set from that query.  (The original article is here, and I will fully admit that all I did was take this author’s idea (and that of one of the commenters) and stick it into this sample report  – https://www.mssqltips.com/sqlservertip/5757/create-dynamic-ssrs-reports-using-a-query-as-an-input-parameter/ ). I wanted to see if this worked for Paginated Reports in Power BI, and of course it does!  So once I put in my connection string information for my Azure SQL database (the original article was against a traditional SQL Server database), I can write just about any select query against that database as a parameter at runtime and get back results in a nice table that can be exported out to Microsoft Excel.  I created a short video to show you how it works in practice –

Now there’s little chance I’d use this report as is in production – it’s really just a way for me to test some things, dump out data quickly, and it demos nicely.  But there are some ways you could potentially change this to make it more production friendly – have a list of dropdown values that represent the queries that you update on an ongoing basis, or even allow users to submit queries through a workflow you approve that updates the parameter list.

If you’d like to try it out yourself, feel free to download the sample report –

Ultimate Export Report

Once downloaded, you’ll need to update the data source with your connection string to whatever database you’ll use this against in Power BI Report Builder before you can use it in the service, but once you do that, you should be good to go.

Use a Conditional Preview Image in Paginated Reports subscriptions in Power BI

Recently in Power BI, a new feature was added for Paginated Reports e-mail subscriptions where you could optionally add a preview image in the body of your e-mail message.  By default, this is the first page of your report.  However, it doesn’t have to be.  For example, in my e-mail subscription, I see the following preview image –

image  

But when I view the report in the PDF attachment or in the web, I see the following report links as my first page –

image

How is this possible?

Well, one of the cool things you can do with Paginated Reports is set the visibility of items in your report to be conditional.  You do this by adding an expression that sets the condition for when it should be shown or hidden.  Since the preview image in your e-mail subscription uses the “IMAGE” output format, all I did was set the visibility of an item to be conditional based on that.  So I took all of the items you see in that preview image and added them to a tablix, then made that conditionally visible based on the following expression –
=ucase(Globals!RenderFormat.Name) <> “IMAGE”   

Now, the report renderer knows to hide that part of the report whenever the renderer is something other than the “IMAGE” output format.  I’ve attached the sample report below so you can try this out yourself.  You can test this in the Power BI service (if you have Premium) by setting up a new e-mail subscription with it, or in Power BI Report Builder by exporting it to a TIFF file.
