• What is the cause and solution for SAP error message AQ366 - Error in generated report; selection screen is too big ?

  The SAP error message AQ366, which states "Error in generated report; selection screen is too big," typically occurs when the selection screen for a report exceeds the allowed limits in terms of the number of fields or the overall size of the screen. This can happen in various scenarios, especially when dealing with complex reports or when many selection criteria are defined.
  Causes:
  
  Excessive Number of Fields: The report may have too many selection fields defined, which can lead to a screen that is too large to be processed.
  Field Lengths: The combined length of the fields on the selection screen may exceed the maximum allowed size.
  Dynamic Selection Criteria: If the report allows for dynamic selection criteria, it may inadvertently add too many fields based on user input or configuration.
  Custom Modifications: Custom developments or modifications to standard reports can sometimes lead to this issue if not properly managed.
  
  Solutions:
  
  Reduce the Number of Fields: Review the selection criteria and remove any unnecessary fields. Try to simplify the selection screen by consolidating fields or using ranges instead of individual fields.
  Use Variants: If applicable, create variants for the report that limit the number of fields displayed on the selection screen. This can help manage the complexity and size of the screen.
  Check for Dynamic Selections: If the report uses dynamic selections, ensure that they are not adding excessive fields. Limit the options available to users if possible.
  Review Custom Code: If the report has been customized, review the code to ensure that it adheres to SAP's guidelines for selection screens. Consider refactoring the code to reduce the number of fields.
  Split the Report: If the report is inherently complex and requires many selection criteria, consider splitting it into multiple reports or creating a more focused report that addresses specific needs.
