  SAP Error Message:
  W0138 - Own logical system cannot be used as the original system
  
  
  Cause:
  This warning message occurs in the context of ALE (Application Link Enabling) or IDoc processing when the logical system name of the current SAP system (the "own logical system") is mistakenly used as the "original system" in an IDoc or distribution model.
  
  The own logical system is the identifier of the current SAP system.
  The original system is supposed to be the system where the data originated.
  Using the same logical system for both means the system is trying to treat itself as the source of data, which is logically incorrect in scenarios like inbound IDoc processing or distribution.
  
  This usually happens if:
  
  The logical system name is incorrectly maintained in the partner profiles.
  The IDoc header contains the same logical system as both sender and receiver.
  The distribution model or partner profiles are incorrectly configured.
  
  
  When does it occur?
  
  During inbound IDoc processing.
  When distributing data
