• What is the cause and solution for SAP error message DMC_MDS_MAINT_EVENT135 - There are already trkorrs from buffer & mapped ?

  The SAP error message DMC_MDS_MAINT_EVENT135 typically indicates that there are already transport requests (TRKORRs) in the buffer that are mapped to the same object or data that you are trying to modify or transport. This can occur in various scenarios, particularly when working with the Data Migration Cockpit (DMC) or during data maintenance activities.
  Cause:
  
  Existing Transport Requests: The error suggests that there are existing transport requests that have not been released or are still in the buffer for the same objects you are trying to work with.
  Concurrent Modifications: Another user or process may be trying to modify the same data or object simultaneously, leading to conflicts.
  System Configuration Issues: There may be issues with the configuration of the transport management system or the way the DMC is set up.
  
  Solution:
  
  
  Check Existing Transport Requests:
  
  Use transaction code SE09 or SE10 to check for existing transport requests that are related to the objects you are trying to modify. If you find any, you may need to release or delete them if they are no longer needed.
  
  
  
  Release Transport Requests:
  
  If you have identified transport requests that are blocking your operation, consider releasing them if they are ready to be moved to the next system.
  
  
  
  Clear Buffer:
  
  If you suspect that the buffer is holding onto old transport requests, you can try to clear the buffer. This can sometimes be done by restarting the transport management system or using specific SAP commands.
  
  
  
  Check for Concurrent Users:
  
  Ensure that no other users are trying to modify the same data or objects at the same time. Coordination among team members can help avoid such conflicts.
