  The SAP error message CNVA_20400_CHECK026 indicates that there is an issue with the implicit merging of cost centers due to a mapping problem in the controlling area. This typically occurs during data migration or when integrating different controlling areas in SAP.
  Cause:
  The error arises when the system detects that cost centers from different controlling areas are being merged implicitly, which is not allowed. This can happen due to:

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Cost Center Mapping:
