• What is the cause and solution for SAP error message CNV_20335_CHECK012 - No target provided for source &1. Mapping is not complete ?

  The SAP error message CNV_20335_CHECK012 indicates that there is an issue with the mapping of source and target fields during a data migration or conversion process. Specifically, the error states that no target has been provided for a given source field, which means that the mapping is incomplete.
  Cause:
  
  Incomplete Mapping: The primary cause of this error is that the source field (indicated by &1) does not have a corresponding target field defined in the mapping configuration.
  Configuration Issues: There may be issues in the configuration settings of the data migration tool or the specific mapping rules that have not been set up correctly.
  Data Model Changes: Changes in the data model (e.g., changes in the source or target structures) that have not been reflected in the mapping configuration can lead to this error.
  Missing Entries: The mapping table may be missing entries for certain source fields, leading to the absence of a target field.
  
  Solution:
  
  
  Check Mapping Configuration:
  
  Go to the mapping configuration in the data migration tool (e.g., SAP S/4HANA Migration Cockpit, LTMC, or other tools).
  Verify that all source fields have corresponding target fields defined. If any source field is missing a target, you need to create or update the mapping.
  
  
  
  Update Mapping Rules:
  
  If the mapping rules are not complete, update them to ensure that every source field has a defined target field.
  Ensure that the mapping is consistent with the current data model.
  
  
  
  Review Data Model Changes:
  
  If there have been recent changes to the data model, review those changes and update the mapping accordingly.
  Ensure that any new fields in the target structure are accounted for in the mapping.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or guides related to the specific data migration tool you are using for any additional configuration steps or requirements.
  
  
  
  Testing:
  
  After making the necessary changes, perform a test run of the migration process to ensure that the error is resolved and that the mapping works as expected.
  
  
  
  Related Information:
  
  Transaction Codes: Depending on the tool you are using, you may need to use specific transaction codes to access the mapping configuration (e.g., LTMC for Migration Cockpit).
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on mapping issues.
  Community Forums: Consider searching or posting in SAP community forums for insights from other users who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the CNV_20335_CHECK012 error and complete the mapping process successfully.
