Company code mapping values result in implicit merges. Adjust your
mapping values accordingly. You must also add company codes as source

CNVA_20290_CHECK202 - Details

• The SAP error message CNVA_20290_CHECK202 indicates that there are implicit merges occurring due to the mapping of company codes during a data migration or system conversion process. This typically arises in scenarios such as SAP S/4HANA migrations or data transfers where company codes are being consolidated or mapped incorrectly.
  
  Cause:
  
  Company Code Mapping Issues: The error suggests that multiple company codes are being mapped to a single target company code, which leads to implicit merges. This can happen if the mapping configuration is not set up correctly or if there are overlaps in the source data.
  Data Overlap: If the source company codes have overlapping data (e.g., customers, vendors, or financial transactions), the system may not know how to handle these overlaps during the migration.
  Configuration Errors: Incorrect settings in the migration cockpit or data transfer tools can lead to this error.
  
  
  Solution:
  
  Review Mapping Configuration: Check the mapping of company codes in the migration cockpit
