• What is the cause and solution for SAP error message WZRE_ALE_MONITOR2004 - Number of selected IDocs (&1) deviates from expected value (&2) ?

  SAP Error Message:
  
  WZRE_ALE_MONITOR2004
  
  Text: Number of selected IDocs (&1) deviates from expected value (&2)
  
  Cause:
  This error occurs in the ALE (Application Link Enabling) monitoring or processing when the number of IDocs selected for processing does not match the expected number. Typically, this happens during IDoc monitoring or batch processing when the system expects a certain count of IDocs but finds a different number.
  Possible reasons include:  
  
  IDocs have been deleted or archived after selection but before processing.  
  IDocs are filtered or selected incorrectly due to selection criteria mismatch.  
  Parallel processing or background jobs have already processed some IDocs, reducing the count.  
  Inconsistent or outdated data in the IDoc control tables (e.g., EDIDC, EDIDS).  
  Transport or system inconsistencies in ALE configuration or partner profiles.
  
  
  Solution:
  
  
  Check the selection criteria:
  
  Verify the selection parameters used for IDoc processing or monitoring. Ensure they correctly reflect the intended IDocs.
  
  
  Verify IDoc status and existence:
  
  Use transaction WE02 or WE05 to check the status and number of IDocs currently available for processing. Confirm that the IDocs expected are still present and not already processed or deleted.
  
  
  Check for parallel processing:
  
  Ensure no other jobs or processes are simultaneously processing the same IDocs, which could reduce the number available.
  
  
  Review ALE configuration:
  
  Check partner profiles (transaction WE20) and distribution model (transaction BD64) for correctness.
  
  
  Re-run or adjust the process:
  
  If the discrepancy is due to timing or transient issues, re-run the process or adjust the expected number accordingly.
  
  
  Check for system inconsistencies:
  
  Run consistency checks on IDoc tables or ALE configuration if needed.

  Summary:
  
  The error indicates a mismatch between the number of IDocs expected and those actually selected for processing. Investigate selection criteria, IDoc status, and concurrent processing to resolve the issue.
