This error indicates that there are implicit merges occurring in the account mapping, which can lead to inconsistencies or data integrity issues.
  Cause:
  The error is often caused by:
  
  Implicit Merges: This occurs when multiple accounts are being mapped to a single target account without proper handling, leading to potential data loss or misrepresentation.
  Inconsistent Mapping: If the mapping rules are not clearly defined or if there are overlaps in the source accounts that are being mapped to the same target account, it can trigger this error.

  Solution:
  To resolve the CNV_20100531 error, consider the following steps:

  Data Cleansing: Perform data cleansing on the source data to eliminate duplicates or inconsistencies that could lead to implicit merges. Ensure that the data is accurate and conforms to the expected formats.
  
  
  Testing: After making adjustments, conduct thorough testing of the mapping process to ensure that the changes resolve the error and that the data integrity is maintained.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion process you are using. There may be specific guidelines or best practices that can help in resolving this error.
