• What is the cause and solution for SAP error message SCWN852 - Cannot deimplement note &1 (no backup of transport-based instruction &2) ?

  The SAP error message SCWN852 indicates that there is an issue with deimplementing a support package or a note in the SAP system. Specifically, it means that the system cannot deimplement the specified note because there is no backup of the transport-based instruction associated with it.
  
  Cause:
  
  Missing Backup: The primary cause of this error is that there is no backup of the transport request that was used to implement the note. When a note is implemented, a transport request is created, and if there is no backup of this request, the system cannot reverse the changes made by the note.
  Manual Changes: If manual changes were made to the objects affected by the note after its implementation, this could also lead to issues when trying to deimplement it.
  Transport Request Deletion: If the transport request was deleted or not properly recorded in the system, it would lead to this error.
  
  
  Solution:
  
  Check Transport Request: Verify
