• What is the cause and solution for SAP error message GA791 - Reference data read from summarization level &1 ?

  The SAP error message GA791, which states "Reference data read from summarization level &1," typically occurs in the context of the SAP Controlling (CO) module, particularly when dealing with Profitability Analysis (CO-PA) or other areas where data summarization is involved. This message indicates that the system is trying to read reference data from a specific summarization level, but it encounters an issue.
  Cause:
  
  Missing Data: The summarization level specified may not have any data available. This can happen if the data has not been summarized correctly or if the summarization process has not been executed.
  Configuration Issues: There may be configuration issues related to the summarization levels in the system. This could include incorrect settings in the CO-PA configuration or issues with the data model.
  Data Consistency: There might be inconsistencies in the data that prevent the system from reading the reference data correctly.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to access the data at the specified summarization level.
  
  Solution:
  
  Check Summarization Levels: Verify that the summarization level specified in the error message is correctly configured and that data exists for that level. You can do this by checking the relevant CO-PA reports or tables.

  Review Configuration: Check the configuration settings for CO-PA or the relevant module to ensure that everything is set up correctly. This includes checking the characteristics and value fields used in the summarization.
  Data Consistency Check: Perform a data consistency check to identify any issues with the underlying data. This may involve running reports or using transaction codes that help identify inconsistencies.
