• What is the cause and solution for SAP error message DMC_GENERAL280 - Objects to be created already exist for specified tables of MT ID &1 ?

  The SAP error message DMC_GENERAL280 indicates that there are objects that you are trying to create in the Data Migration Cockpit (DMC) that already exist for the specified tables associated with the given Migration Template ID (MT ID). This typically occurs during data migration processes when you attempt to create or load data into tables that already have existing entries or structures.
  Cause:
  
  Existing Objects: The most common cause is that the objects (like data records, structures, or configurations) you are trying to create already exist in the target system.
  Duplicate Migration Attempts: If a migration process was previously executed and not properly cleaned up, it may lead to conflicts when trying to run the migration again.
  Incorrect Configuration: There may be a misconfiguration in the migration template or the mapping that leads to attempts to create objects that are already present.
  
  Solution:
  
  Check Existing Objects: Verify if the objects you are trying to create already exist in the target system. You can do this by querying the relevant tables or using transaction codes like SE11 or SE16.
  Delete or Update Existing Entries: If the existing objects are not needed, you can delete them. If they need to be updated, consider modifying the existing entries instead of creating new ones.
  Adjust Migration Template: Review the migration template and ensure that it is correctly configured to avoid conflicts with existing data.
  Run Cleanup Jobs: If applicable, run any cleanup jobs or processes that may remove or reset the existing data before attempting the migration again.
  Consult Logs: Check the logs for more detailed error messages or warnings that can provide additional context on what is causing the conflict.
