• What is the cause and solution for SAP error message RMPS_TRF152 - Import stack already exists ?

  The SAP error message RMPS_TRF152, which states "Import stack already exists," typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when there is an attempt to import a stack that has already been imported or is currently in the process of being imported.
  Cause:
  
  Duplicate Import Attempt: The most common cause of this error is that the import stack you are trying to import has already been imported into the system.
  Incomplete Previous Import: If a previous import was interrupted or did not complete successfully, it might leave remnants in the system that prevent a new import.
  System Lock: The system might be locked due to another ongoing import process, leading to this error when trying to initiate a new import.
  
  Solution:
  
  Check Existing Imports: Verify if the import stack you are trying to import is already present in the system. You can do this by checking the import history in the SAP system.
  Remove Duplicate Stack: If the stack is indeed present and you want to replace it, you may need to remove the existing stack before attempting the import again. This can usually be done through the SAP PI/PO administration interface.
  Check for Ongoing Processes: Ensure that no other import processes are currently running. You can check the status of ongoing processes in the SAP system.
  Clear Incomplete Imports: If a previous import was interrupted, you may need to clear any incomplete imports. This might involve using transaction codes like SXMB_MONI or SXI_MONI to monitor and manage integration processes.
  Restart the Import Process: After ensuring that there are no existing imports or locks, try to restart the import process.
  
  Related Information:
