• What is the cause and solution for SAP error message RSENQ002 - Lock NOT set for: & ?

  The SAP error message RSENQ002 indicates that a lock could not be set for a specific object, which is typically related to the enqueue mechanism in SAP. This error often occurs in the context of background jobs, data processing, or when multiple users or processes attempt to access the same resource simultaneously.
  Cause:
  
  Lock Already Held: The most common cause is that another process or user is already holding a lock on the object you are trying to access.
