Syntax

ReportParameters :=   Report.RunRequestPage([PageParameters: Text])

Parameters

Report
 Type: Report
An instance of the Report data type.

[Optional] PageParameters
 Type: Text
A string of request page parameters as XML to use to run the report.

Return Value

ReportParameters
 Type: Text
XML string that contains the request page parameters that are entered on the request page

Remarks

This method opens the request page for the specified report, where the user can provide parameters for the report. When the user closes the request page by choosing the OK button, a string that contains the parameter values that were set by the user is returned. When the user chooses the Cancel button, an empty string will be returned. The returned parameter string can be picked up by calling one of the following methods:

Note

You can use these methods to schedule reports in the job queue.

Because the request page runs in the context of where it was invoked from, users cannot bookmark a link to this page from the user interface.

Example

This example illustrates how to use the RunRequestPage method to run the request page for report ID 206 Sales Invoice. The request page parameters are saved to a table, and then uses the parameters with the Execute, SaveAs, and Print methods to preview the report, save it as a PDF file, and print it.

This example requires that you create a table for holding parameters that are entered on the report request page and a codeunit that runs the report methods.

Create a table called Request Parameters that has the following fields.

var
    ReportId: Integer;
    UserId: Code[100];
    Parameters: BLOB;

Create a codeunit and add the following code to the OnRun trigger of the codeunit.

var
    ReportParameters: Record "Report Parameters";
    XmlParameters: Text;
    OStream: OutStream;
    IStream: InStream;
    CurrentUser: Code[100];
    Content: File;
    TempFileName: Text;
begin
    // Use the Report.RunRequestPage method to run the request page to get report parameters  
    XmlParameters := Report.RunRequestPage(206);  
    CurrentUser := UserId;  
    
    // Save the request page parameters to the database table  
    with ReportParameters do begin  
        // Cleanup  
        if Get(206,CurrentUser) then  
        Delete;  
    
        SetAutoCalcFields(Parameters);  
        ReportId := 206;  
        UserId := CurrentUser;  
        Parameters.CreateOutStream(OStream,TextEncoding::UTF8);  
        Message(XmlParameters);  
        OStream.WriteText(XmlParameters);  
    
        Insert;  
    end;  
    
    Clear(ReportParameters);  
    XmlParameters := '';  
    
    // Read the request page parameters from the database table  
    with ReportParameters do begin  
        SetAutoCalcFields(Parameters);  
        Get(206,CurrentUser);  
        Parameters.CreateInStream(IStream,TextEncoding::UTF8);  
        IStream.ReadText(XmlParameters);  
    end;  
    
    // Use the Report.SaveAs method to save the report as a PDF file  
    Content.Create('TestFile.pdf');  // only supported in Business Central on-premises
    Content.CreateOutStream(OStream);  // only supported in Business Central on-premises
    Report.SaveAs(206,XmlParameters,ReportFormat::Pdf,OStream);  
    Content.Close;  // only supported in Business Central on-premises
    
    // Use the Report.Execute method to preview the report  
    Report.Execute(206,XmlParameters);  
    
    // Use the Report.Print method to print the report  
    Report.Print(206,XmlParameters);  
end;
