  The SAP error message SRT_WSP2455 indicates that an interface assignment in the SAP system is not locked and therefore cannot be changed. This typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when you are trying to modify an interface assignment that is currently in use or not properly locked for editing.
  Cause:

  Technical Issues: There may be a technical issue or inconsistency in the system that is preventing the locking mechanism from functioning correctly.
  
  Solution:
  
  Check for Active Sessions: Ensure that no other users or processes are currently using the interface assignment. You can check active sessions in transaction SM04 or SM12.
  Lock the Interface Assignment: If you have the necessary authorizations, try to manually lock the interface assignment before making changes. This can often be done in the relevant configuration transaction.
  Wait and Retry: If the interface assignment is being used by another user, you may need to wait until they have finished their work before attempting to make changes again.
  Check Authorizations: Ensure that your user account has the necessary authorizations to modify interface assignments. You may need to consult with your SAP security team.
  System Consistency Check: If you suspect a technical issue, you may need to perform a consistency check or consult with your SAP Basis team to resolve any underlying issues.
