• What is the cause and solution for SAP error message GR920 - Standard reports already exist for the tables selected ?

  The SAP error message GR920, which states "Standard reports already exist for the tables selected," typically occurs when you attempt to create a new report or query in SAP that is already covered by existing standard reports. This is a safeguard to prevent redundancy and ensure that users are not duplicating efforts in creating reports that already exist.
  Cause:
  
  Existing Standard Reports: The primary cause of this error is that SAP has already provided standard reports for the tables you are trying to use. This is common in modules like MM (Materials Management), SD (Sales and Distribution), and FI (Financial Accounting), where many standard reports are available.
  Table Selection: The specific tables you are trying to create a report for may already have predefined reports associated with them in the SAP system.
  
  Solution:
  
  
  Check Existing Reports: Before creating a new report, check the existing standard reports in the SAP system. You can do this by:
  
  Using transaction codes like SE38 or SA38 to search for existing reports.
  Looking in the SAP Easy Access menu under the relevant module to find standard reports.
  
  
  
  Use Existing Reports: If you find that a standard report meets your requirements, consider using it instead of creating a new one. You can often customize standard reports to fit your needs.
  
  
  Modify Existing Reports: If the standard report is close to what you need but not quite right, you can often modify it or create a variant of the report to suit your specific requirements.
  
  
  Custom Development: If you absolutely need a new report that is not covered by existing ones, you may need to create a custom report using ABAP programming. This would typically involve:
  
  Creating a new report program in transaction SE38.
  Writing the necessary ABAP code to pull data from the required tables.
  
  
  
  Consult Documentation: Review SAP documentation or consult with your SAP support team to understand the existing reports and their functionalities.
  
  
  Related Information:
