• What is the cause and solution for SAP error message W_CB337 - Input of "reuse key" is allowed for reuse cases only ?

  SAP Error Message:
  
  W_CB337 – Input of "reuse key" is allowed for reuse cases only
  
  Cause:
  This warning message occurs when a user tries to enter a reuse key in a context where it is not allowed. The reuse key is a special identifier used in SAP Change and Transport System (CTS) or in Change Management scenarios to indicate that a particular object or change request is being reused from a previous change or transport.
  The system restricts the input of the reuse key only to reuse cases, i.e., when you are explicitly working on a change request or transport that is marked for reuse. If you try to enter a reuse key in a normal (non-reuse) change request or transport, the system issues this warning.
  
  When does this happen?
  
  When creating or modifying a change request or transport request.
  When trying to assign or input a reuse key in a request that is not flagged as a reuse case.
  In Change and Transport Organizer (CTO) or Change Management transactions where reuse keys are relevant.
  
  
  Solution:
  
  
  Check the type of change request or transport request:
  
  Ensure that the request you are working on is indeed a reuse case.
  If it is not a reuse case, do not enter a reuse key.
  
  
  
  If you intend to use reuse functionality:
  
  Make sure the change request or transport request is properly flagged or created as a reuse case.
  Follow the correct procedure to create a reuse request before entering the reuse key.
  
  
  
  Remove the reuse key input:
  
  If you mistakenly entered a reuse key in a non-reuse request, simply delete the reuse key field and proceed.
  
  
  
  Consult your Change Management or Transport Administrator:
  
  If unsure about reuse keys and their usage in your system, consult your SAP Basis or Change Management team for guidance.
  
  
  
  
  Related Information:

  Transactions involved:  
  
  SE01, SE09, SE10 (Transport Organizer)  
  Change Management transactions in Solution Manager or CTS  
  
  
  SAP Notes: Check SAP Notes related to reuse keys and change management for any system-specific corrections or updates.
  
  
  Summary:
  
  W_CB337 warns that reuse keys can only be entered in reuse cases.
  Verify the nature of your change request.
  Only enter reuse keys in requests flagged for reuse.
  Remove reuse key input if not applicable.
