• What is the cause and solution for SAP error message MDC_IMPORT015 - Start import failed; reference object does not exist. ?

  The SAP error message MDC_IMPORT015 ("Start import failed; reference object does not exist") typically occurs during the import of a transport request in the SAP system, particularly in the context of Multi-Dimensional Container (MDC) or when dealing with SAP HANA database objects. This error indicates that the system is unable to find a reference object that is required for the import process.
  Causes:
  
  Missing Objects: The transport request may reference objects (like tables, views, or other database objects) that do not exist in the target system.
  Incorrect Transport Sequence: The transport request may be dependent on other transport requests that have not been imported yet.
  Inconsistent System State: The target system may be in an inconsistent state due to previous failed imports or manual changes.
  Version Mismatch: The source and target systems may be on different versions or have different configurations, leading to missing dependencies.
  
  Solutions:
  
  Check Dependencies: Review the transport request and ensure that all dependent transport requests have been imported into the target system. You can use transaction code SE01 or SE09 to check the transport logs and dependencies.
  Verify Object Existence: Manually check if the referenced objects exist in the target system. You can use transaction codes like SE11 (Data Dictionary) or SE14 (Database Utility) to verify the existence of database objects.
  Import Missing Objects: If you find that certain objects are missing, you may need to import the relevant transport requests that contain those objects.
  Check Transport Directory: Ensure that the transport directory is correctly set up and that there are no issues with the transport files.
  Review Logs: Check the transport logs for more detailed error messages that can provide additional context on what is missing or causing the failure.
  Consult Documentation: Refer to SAP Notes or documentation related to the specific version of SAP you are using, as there may be known issues or patches available.
