• What is the cause and solution for SAP error message DMC_TRANSPORT134 - Foreign key relationships were adapted ?

  The SAP error message DMC_TRANSPORT134 typically indicates that there are issues related to foreign key relationships in the context of data transport or data migration processes, particularly when using the Data Migration Cockpit (DMC) or similar tools. This error suggests that the foreign key relationships in the target system have been adapted or modified, which can lead to inconsistencies or integrity issues in the data.
  Cause:
  
  
  Foreign Key Constraints: The error may arise when the data being transported or migrated violates foreign key constraints in the target system. This can happen if the data being imported does not have corresponding entries in the referenced tables.
  
  
  Data Model Changes: Changes in the data model (e.g., changes in table structures, relationships, or keys) between the source and target systems can lead to this error.
  
  
  Incorrect Mapping: If the mapping of fields between the source and target systems is incorrect, it can lead to foreign key violations.
  
  
  Data Integrity Issues: If the data in the source system is not clean or does not adhere to the expected relationships, it can cause issues during transport.
  
  
  Solution:
  
  
  Check Foreign Key Relationships: Review the foreign key relationships in both the source and target systems. Ensure that all necessary parent records exist in the target system before importing child records.
  
  
  Data Validation: Validate the data in the source system to ensure that it adheres to the foreign key constraints. This may involve cleaning the data or ensuring that all necessary records are present.
  
  
  Adjust Mapping: If you are using a data migration tool, double-check the mapping of fields to ensure that they are correctly aligned with the target system's data model.
  
  
  Transport Order: Ensure that the transport order of the data is correct. Parent records should be transported before child records to maintain referential integrity.
  
  
  Review Logs: Check the logs for more detailed error messages that can provide insights into which specific foreign key relationships are causing the issue.
  
  
  Consult Documentation: Refer to SAP documentation or support resources for specific guidance related to the DMC and the error message.
