• What is the cause and solution for SAP error message CNV_20100362 - Temporary duplicates; CoA &1 is source CoA as well as target CoA ?

  The SAP error message CNV_20100362 indicates that there are temporary duplicates in the context of a conversion process, specifically related to the Chart of Accounts (CoA). This error typically arises during data migration or conversion activities, particularly when using SAP's Conversion Tools or during the implementation of SAP S/4HANA.
  Cause:
  The error occurs when the system detects that the same Chart of Accounts (CoA) is being used as both the source and target CoA in a conversion process. This can happen if:
  
  The mapping of the source and target CoA is incorrectly configured.
  There are duplicate entries in the CoA that are not being handled properly during the conversion.
  The conversion logic is attempting to map accounts in a way that leads to conflicts.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check CoA Configuration:
  
  Review the configuration of the source and target CoA in your migration settings. Ensure that they are correctly defined and that there are no overlaps.
  
  
  
  Review Mapping:
  
  Examine the mapping of accounts between the source and target CoA. Make sure that each account in the source CoA is mapped to a unique account in the target CoA.
  
  
  
  Eliminate Duplicates:
  
  If there are duplicate accounts in the source CoA, you may need to consolidate or eliminate these duplicates before proceeding with the conversion.
  
  
  
  Adjust Conversion Logic:
  
  If you are using custom conversion logic or scripts, review them to ensure they are not inadvertently causing the duplication.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific conversion tool you are using. There may be specific guidelines or patches available that address this issue.
  
  
  
  Testing:
  
  After making adjustments, perform a test run of the conversion process to ensure that the error does not reoccur.
