• What is the cause and solution for SAP error message CNV_20000154 - Ledger groups not present in the system ?

  The SAP error message CNV_20000154: Ledger groups not present in the system typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that the system is unable to find the specified ledger groups that are required for the migration process.
  Cause:
  
  Missing Ledger Groups: The ledger groups that are referenced in the migration data do not exist in the target system. This can happen if the ledger groups were not created or if there was a mismatch in the configuration between the source and target systems.
  Incorrect Configuration: The configuration settings in the target system may not align with the source system, leading to discrepancies in the ledger groups.
  Data Mapping Issues: The mapping of data from the source system to the target system may not have been set up correctly, resulting in references to non-existent ledger groups.
  
  Solution:
  
  
  Check Ledger Group Configuration:
  
  Go to the SAP GUI and check the configuration of ledger groups in the target system. You can do this by navigating to SPRO > Financial Accounting > General Ledger > Master Data > Ledger > Define Ledger Groups.
  Ensure that the required ledger groups are defined and active.
  
  
  
  Create Missing Ledger Groups:
  
  If the required ledger groups are missing, you may need to create them manually in the target system. Ensure that they match the configuration from the source system.
  
  
  
  Review Migration Data:
  
  Check the migration data for any references to ledger groups. Ensure that the data being migrated is correctly mapped to the existing ledger groups in the target system.
  
  
  
  Adjust Mapping Settings:
  
  If you are using a migration tool, review the mapping settings to ensure that they correctly reference the existing ledger groups in the target system.
