  SAP Error Message:
  WZRE_ALE_MONITOR2017 Definition of segments differ: &1 (&2 <-> &3 ). No comparison possible.
  
  Meaning / 
  Cause:
  This error occurs during ALE (Application Link Enabling) monitoring or IDoc processing when the system tries to compare the segment definitions of an IDoc type between two systems (e.g., sender and receiver) or between two versions, but finds that the segment definitions differ.
  
  &1 = Segment name
  &2 = Segment definition in one system (or version)
  &3 = Segment definition in the other system (or version)
  
  The system cannot perform a proper comparison because the segment structures are not identical. This usually happens when:
  
  The IDoc segment structure has been changed in one system but not in the other.
  Different versions of the IDoc or segment are active in the sender and receiver systems.
  Custom segments or modifications have been made inconsistently.
  The segment definitions in the Data Dictionary (DDIC) differ between systems.
