  The SAP error message M2023, which states "Table pool not in DDIC or not active," typically occurs when there is an issue with a table pool in the Data Dictionary (DDIC) of the SAP system. This error can arise due to several reasons, and here are the potential causes, solutions, and related information:
  Causes:
  
  Inactive Table Pool: The table pool may not be activated in the Data Dictionary. This can happen if the table pool was recently created or modified and has not been activated yet.
  Missing Table Pool: The table pool may not exist in the DDIC, possibly due to deletion or an incomplete transport.
