  Cause:
  
  
  Field Mapping Issues: The error often arises when there is an attempt to maintain or modify a field that is not allowed for the specified receiver (target) field. This could be due to:
  
  The field being read-only in the target system.
  The field not being part of the data model for the target entity.

  Solution:
  
  
  Check Field Mapping: Review the field mapping in your data migration project. Ensure that the source fields are correctly mapped to the appropriate target fields. If the target field is not meant to be maintained, remove it from the mapping.

  Check Authorizations: Ensure that the user executing the migration has the necessary authorizations to maintain the specified field. You may need to consult with your SAP security team to verify this.
  
  
  Consult Documentation: Refer to the SAP documentation for the Data Migration Cockpit or the specific migration tool you are using. There may be specific guidelines or limitations regarding the fields you are trying to maintain.
