• What is the cause and solution for SAP error message PU452 - Request &1 is assigned to Support Package request; linking not possible ?

  The SAP error message PU452 indicates that a specific request (denoted by &1) is assigned to a Support Package request, and therefore, linking or performing certain operations with that request is not possible. This typically occurs in the context of transport management and change requests within the SAP system.
  Cause:
  
  Request Assignment: The request you are trying to link or modify is already assigned to a Support Package request. Support Package requests are special types of transport requests that are used to apply updates and patches to the SAP system.
  Transport Management System (TMS) Restrictions: The Transport Management System has restrictions in place to prevent changes to requests that are part of a Support Package to maintain system integrity and avoid conflicts.
  
  Solution:
  
  Check Request Assignment: Verify the assignment of the request in question. You can do this by using transaction code SE01 (Transport Organizer) or SE09 (Workbench Organizer) to see the details of the request and its current status.
  Release the Request: If the request is not needed as part of the Support Package, you may need to release it from the Support Package request. This can typically be done by:
  
  Going to the Support Package request in SE01 or SE09.
  Removing the request from the Support Package.
  
  
  Create a New Request: If the request is indeed needed for the Support Package, consider creating a new transport request for the changes you want to make, rather than trying to link to the existing one.
  Consult with Basis Team: If you are unsure about the implications of modifying transport requests or Support Package requests, it is advisable to consult with your SAP Basis team or system administrator. They can provide guidance on best practices and ensure that system integrity is maintained.
