• What is the cause and solution for SAP error message RSDRI_HDB122 - Structure of A version and M version not identical. Activate ?

  The SAP error message RSDRI_HDB122, which states "Structure of A version and M version not identical. Activate," typically occurs in the context of SAP BW (Business Warehouse) when there is a mismatch between the structure of the Active (A) version and the Modified (M) version of a data model, such as an InfoObject, InfoProvider, or a CompositeProvider.
  Cause:
  
  
  Structural Changes: The most common cause of this error is that changes have been made to the structure of the InfoObject or InfoProvider in the M version (the modified version) that are not reflected in the A version (the active version). This can happen if fields are added, removed, or modified in the M version.
  
  
  Inconsistent Activation: If the M version has not been activated properly, or if there are pending changes that have not been activated, this can lead to discrepancies between the two versions.
  
  
  Transport Issues: If changes were transported from one system to another (e.g., from development to production) and the transport did not include all necessary objects or was not executed correctly, this can also lead to structural mismatches.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Activate the M Version: 
  
  Go to the relevant InfoObject or InfoProvider in the SAP BW system.
  Check if the M version is activated. If not, activate it. This can usually be done in the Data Warehousing Workbench (transaction RSA1) or the relevant modeling tool.
  
  
  
  Check for Structural Changes:
  
  Compare the structures of the A version and M version. You can do this by checking the fields, data types, and attributes in both versions.
  If there are discrepancies, you may need to adjust the M version to match the A version or vice versa, depending on your requirements.
  
  
  
  Re-activate the A Version:
  
  If the M version is already activated and you still encounter the error, try reactivating the A version. This can sometimes resolve inconsistencies.
  
  
  
  Check Transport Logs:
  
  If the issue arose after a transport, check the transport logs for any errors or warnings that might indicate what went wrong during the transport process.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to this error message for any specific guidance or updates that may apply to your version of SAP BW.
  
  
  
  Seek Help from SAP Support:
  
  If the issue persists after trying the above steps, consider reaching out to SAP support for further assistance.
