• What is the cause and solution for SAP error message CNV_20345_CHECK016 - No source provided for target &1; mapping is not complete ?

  The SAP error message CNV_20345_CHECK016 indicates that there is an issue with the data mapping in a conversion or migration process. Specifically, it means that there is no source data provided for a target mapping, which suggests that the mapping configuration is incomplete.
  Cause:
  
  Incomplete Mapping Configuration: The mapping between the source and target data structures is not fully defined. This could happen if the source fields are not correctly assigned to the target fields.
  Missing Source Data: The source data that is supposed to be mapped to the target structure is either missing or not correctly identified in the configuration.
  Incorrect Configuration: There may be errors in the configuration settings or parameters that define how the data should be mapped from the source to the target.
  
  Solution:
  
  
  Check Mapping Configuration:

  Ensure that there are no missing entries in the mapping table.
  
  
  
  Review Source Data:
  
  Ensure that the source data is available and correctly loaded into the system. If the source data is missing, you will need to load it before proceeding with the mapping.
  
  
  
  Validate Data Structures:
  
  Check the data structures of both the source and target to ensure they are compatible and that all required fields are present.
  
  
  
  Consult Documentation:
