  The SAP error message CNV_20900243 typically arises during the data migration process, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there are conflicts in the customizing settings between the old and new account groups. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Account Group Conflicts: The error usually occurs when there are discrepancies between the account groups defined in the legacy system and those in the target system. This can happen if:
  
  The same account group is defined differently in the old and new systems.
  There are missing or inactive account groups in the target system that are referenced in the source system.
  Customizations or configurations in the old system do not match those in the new system.
  
  
  
  Data Inconsistencies: If the data being migrated references account groups that do not exist or are not properly configured in the target system, this can lead to conflicts.
  
  
  Solution:
  
  
  Review Account Groups: 
  
  Check the account groups in both the source and target systems. Ensure that they are consistent and that any necessary account groups are created in the target system.
  Use transaction codes like OBD4 (for account groups) to review and compare the configurations.
  
  
  
  Adjust Customizing Settings:
  
  If there are differences in the customizing settings, you may need to adjust the settings in the target system to match those in the source system.
  Ensure that all necessary account groups are active and properly configured in the target system.
  
  
  
  Data Mapping:
  
  If the account groups have changed, you may need to create a mapping strategy to ensure that data from the old account groups is correctly assigned to the new account groups during migration.
  
  
  
  Consult Documentation:
  
  Review the migration documentation provided by SAP for any specific instructions or considerations related to account groups.
  
  
  
  Testing:
  
  After making adjustments, perform a test migration to ensure that the conflicts are resolved and that data is migrated correctly.
  
  
  
  Related Information:
