• What is the cause and solution for SAP error message CNV_20345_CHECK015 - No target provided for source &1; mapping is not complete ?

  The SAP error message CNV_20345_CHECK015 indicates that there is an issue with the data mapping in a conversion or migration process. Specifically, it means that for a given source field (denoted by &1), there is no corresponding target field defined, which results in an incomplete mapping.
  Cause:
  
  Incomplete Mapping Configuration: The mapping between source and target fields has not been fully defined. This can happen if the mapping was not set up correctly during the configuration of the data migration or conversion project.
  Missing Target Fields: The target structure may not have been properly defined or may be missing fields that correspond to the source fields.
  Data Model Changes: Changes in the data model (e.g., during an upgrade or system migration) may have led to discrepancies in the mapping configuration.
  
  Solution:
  
  
  Check Mapping Configuration:
  
  Go to the mapping configuration in the SAP system where the migration or conversion is set up.
  Verify that all source fields have corresponding target fields defined. If any are missing, add the necessary mappings.
  
  
  
  Review Data Structures:
  
  Ensure that the target structure is correctly defined and includes all necessary fields that correspond to the source fields.
  If there have been changes to the data model, update the mapping accordingly.
  
  
  
  Use Transaction Codes:
  
  Use relevant transaction codes (like LTMC for Migration Cockpit or SCC1 for client copy) to check the migration settings and mappings.
  You may also use transaction SE11 to check the data dictionary for the structures involved.
  
  
  
  Consult Documentation:
  
  Review any documentation related to the migration or conversion process to ensure that all steps have been followed correctly.
  
  
  
  Testing:
