• What is the cause and solution for SAP error message E0123 - Last IDoc number could not be determined (number range) ?

  The SAP error message E0123, which states "Last IDoc number could not be determined (number range)," typically occurs when the system is unable to retrieve the last used IDoc number from the number range object associated with IDocs. This can happen for several reasons, including issues with the number range configuration or the number range being exhausted.
  Causes:
  
  Number Range Configuration Issues: The number range for IDocs may not be properly configured or may not exist.
  Exhausted Number Range: The defined number range for IDocs may have been exhausted, meaning that all available IDoc numbers have been used.
  Authorization Issues: The user may not have the necessary authorizations to access or modify the number range.
  System Configuration Errors: There may be inconsistencies or errors in the system configuration related to IDocs.
  
  Solutions:
  
  
  Check Number Range Configuration:
  
  Go to transaction code SNRO (Number Range Objects).
  Look for the number range object related to IDocs, typically IDOC or IDOCNUM.
  Ensure that the number range is defined correctly and is active.
  
  
  
  Adjust Number Range:
  
  If the number range is exhausted, you can extend it by going to the same transaction (SNRO) and adjusting the upper limit of the number range.
  You can also create a new number range if necessary.
  
  
  
  Check Authorizations:
  
  Ensure that the user has the necessary authorizations to access and modify the number range. This can be checked in transaction SU53 or by consulting with your security team.
  
  
  
  Check for System Errors:
  
  Review system logs for any errors that might indicate issues with the IDoc processing or number range management. You can use transaction SLG1 to check application logs.
  
  
  
  Restart IDoc Processing:
  
  Sometimes, simply restarting the IDoc processing can resolve temporary issues. You can do this by reprocessing the IDocs in transaction WE19 (Test tool for IDocs).
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that might address this specific error. There may be patches or updates that resolve known issues.
