• What is the cause and solution for SAP error message STC_SC_TASKS165 - Select only lock TMS queues or only unlock TMS queues ?

  The SAP error message STC_SC_TASKS165 indicates that there is a conflict in the selection of TMS (Transport Management System) queues in the context of a transport request. This error typically arises when you attempt to perform an operation that involves both locking and unlocking TMS queues simultaneously, which is not allowed.
  Cause:
  The error occurs when:
  
  You are trying to select both lock and unlock operations for TMS queues in a single action.
  The system is configured to only allow one type of operation (either lock or unlock) at a time for TMS queues.
  
  Solution:
  To resolve this error, you should:
  
  Review Your Selection: Ensure that you are only selecting either lock or unlock operations for the TMS queues, not both.
  Separate Operations: If you need to perform both operations, do them in separate actions. First, execute the lock operation, and once it is completed, you can then proceed with the unlock operation.
  Check for Active Processes: Make sure there are no other active processes that might be locking the TMS queues, which could prevent your operation from completing successfully.
  Consult Documentation: Refer to the SAP documentation or help resources for more detailed guidance on managing TMS queues and understanding the implications of locking and unlocking.
  
  Related Information:
  
  TMS (Transport Management System): TMS is used in SAP environments to manage the transport of objects between different systems (e.g., development, quality assurance, production).
  Locking Mechanism: Locking TMS queues is a way to prevent changes to transport requests while they are being processed, ensuring data integrity.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as STMS (Transport Management System) and SE01 (Transport Organizer) for managing transport requests and queues.
