• What is the cause and solution for SAP error message CNV_PE537 - Link field &1 is assigned to more than one data field ?

  The SAP error message CNV_PE537 indicates that a link field is assigned to more than one data field in the context of data migration or conversion processes, typically when using the SAP Data Migration Workbench or similar tools. This error can occur during the mapping of fields in a data migration project, where the system detects that a single link field is being incorrectly associated with multiple target fields.
  Cause:
  
  Incorrect Mapping: The most common cause is that the mapping configuration has been set up incorrectly, where a single link field is mapped to multiple data fields.
  Duplicate Entries: There may be duplicate entries in the mapping configuration that lead to confusion in the data migration process.

  Solution:
  
  
  Review Mapping Configuration: Check the mapping configuration for the data migration project. Ensure that each link field is only assigned to one data field. If a link field needs to be associated with multiple data fields, consider creating separate link fields for each association.
  
  
  Remove Duplicates: If there are duplicate mappings, remove or consolidate them to ensure that each link field is uniquely assigned.
  
  
  Consult Documentation: Refer to the SAP documentation or guidelines for the specific data migration tool you are using. This can provide insights into the correct configuration and best practices.
  
  
  Test Changes: After making adjustments to the mapping, run a test migration to ensure that the error is resolved and that the data is being migrated correctly.
