• What is the cause and solution for SAP error message CNV_20100163 - &1 &2 is already contained in mapping for secondary cost elements ?

  The SAP error message CNV_20100163 indicates that there is a conflict in the mapping of secondary cost elements during a data migration or conversion process. This error typically arises when you are trying to map a secondary cost element that has already been mapped to another primary cost element or is already present in the mapping table.
  Cause:
  
  Duplicate Mapping: The secondary cost element you are trying to map is already associated with another primary cost element in the mapping table.
  Incorrect Data Entry: There may be an error in the data entry where the same secondary cost element is being referenced multiple times.
  Configuration Issues: There might be issues in the configuration of the mapping process or the migration tool being used.
  
  Solution:
  
  Review Mapping Entries: Check the mapping table for existing entries. Ensure that the secondary cost element is not already mapped to another primary cost element.
  Remove Duplicates: If you find that the secondary cost element is indeed duplicated, remove or correct the duplicate entry to ensure that each secondary cost element is uniquely mapped.
  Correct Data: If the error is due to incorrect data entry, correct the entries in the mapping table to reflect the intended mappings.
  Consult Documentation: Refer to the SAP documentation or migration tool guidelines for specific instructions on how to handle mapping conflicts.
  Testing: After making changes, test the mapping process again to ensure that the error does not reoccur.
