  SAP Error Message:
  
  WZRE_ALE_MONITOR018 Number of deviations (Control record &; segments &)  
  
  Cause:
  This error message typically appears in the context of ALE (Application Link Enabling) monitoring and indicates that there are deviations or inconsistencies detected between the control record and the segments of an IDoc (Intermediate Document). Specifically, the number of deviations found in the control record and the segments does not match the expected values or thresholds.
  Common causes include:  
  
  Incomplete or corrupted IDoc data during transmission.  
  Mismatches between the control record and segment data due to data inconsistencies.  
  Errors in the ALE distribution model or partner profiles.  
  Network or communication issues causing partial or incorrect IDoc delivery.  
  Incorrect or missing configuration in the ALE setup.
  
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Check the IDoc in WE02/WE05:  
  
  Use transaction WE02 or WE05 to display the IDoc and analyze the control record and segment data.  
  Look for inconsistencies or missing segments.
  
  
  
  Verify Partner Profiles (WE20):  
  
  Ensure that the partner profiles are correctly configured for the message type and process code.  
  Check that the inbound and outbound parameters are consistent.
  
  
  
  Check Distribution Model (BD64):  
  
  Verify that the distribution model is correctly maintained and activated.  
  Ensure that the message types and filters are properly set.
  
  
  
  Reprocess or Re-send the IDoc:  
  
  If the IDoc is incomplete or corrupted, try to reprocess it or resend the data from the sending system.
  
  
  
  Check ALE Configuration:  
  
  Review ALE settings and ensure that the logical systems are correctly defined and assigned.  
  Check for any recent changes in configuration that might have caused the issue.
  
  
  
  Monitor Network and Communication:  
  
  Ensure stable network communication between systems involved in ALE.  
  Check for any errors in the communication layer (SM58, SMQ1/SMQ2 for queues).
  
  
  
  Apply SAP Notes:  
  
  Search for relevant SAP Notes using the message number or keywords.  
  Apply any recommended patches or corrections.
