• What is the cause and solution for SAP error message CNV_PE_CHECK_V2103 - Trans. opt. &1, step &2, par. &3: No field mapping allowed (link field) ?

  The SAP error message CNV_PE_CHECK_V2103 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there is an issue with field mapping in the context of a link field, which is a field that references another table or entity.
  Cause:
  The error message suggests that the system has encountered a situation where field mapping is not allowed for a specific link field. This can happen due to several reasons:
  
  Incorrect Mapping Configuration: The mapping configuration for the data migration might be incorrect, particularly for fields that are supposed to link to other tables.
  Link Field Restrictions: Certain fields in SAP are designated as link fields, and the system may not allow direct mapping to these fields.
  Data Structure Issues: The data structure being migrated may not align with the expected structure in the target system, leading to issues with how fields are linked.
  Missing Dependencies: The linked field may depend on other fields or entities that are not properly defined or are missing in the migration process.
  
  Solution:
  To resolve the CNV_PE_CHECK_V2103 error, you can take the following steps:
  
  
  Review Mapping Configuration:
  
  Check the mapping configuration for the specific transaction option, step, and parameter mentioned in the error message.
  Ensure that the mapping for link fields is correctly defined and that you are not trying to map a link field directly.
  
  
  
  Adjust Data Structure:
  
  Verify that the data structure you are migrating matches the expected structure in the target system.
  Make any necessary adjustments to the source data to ensure compatibility.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific migration tool you are using. There may be guidelines on how to handle link fields and their mappings.
  
  
  
  Use Alternative Mapping:
  
  If direct mapping is not allowed, consider using alternative methods to populate the link fields, such as using a reference table or pre-processing the data to ensure that the link fields are populated correctly.
  
  
  
  Check for Dependencies:
  
  Ensure that all dependencies for the link fields are satisfied. This may involve ensuring that related records exist in the target system before attempting to map the link fields.
  
  
  
  Testing:
  
  After making adjustments, perform a test migration to see if the error persists. This can help identify if further changes are needed.
