• What is the cause and solution for SAP error message WG011 - PO with no. & created ?

  SAP Error Message:
  
  WG011 – PO with no. & created
  
  Meaning / Cause:
  The message WG011 typically appears during the creation of a Purchase Order (PO) in SAP. It indicates that the PO number has already been created or assigned. This can happen in scenarios such as:
  
  The PO number you are trying to create already exists in the system.
  There is a number range issue where the system tries to assign a PO number that is already used.
  A background process or user has already created the PO with the same number.
  The system is trying to create a PO with a manually entered PO number that conflicts with an existing one.
  
  
  When does it occur?
  
  During manual PO creation when entering a PO number that already exists.
  During automatic PO creation (e.g., via message processing or batch jobs) when the number range is not properly maintained or overlapping.
  When number range objects are not properly configured or synchronized.
  
  
  Solution / How to fix:
  
  
  Check if the PO number already exists:
  
  Use transaction ME23N or ME22N to check if the PO number mentioned in the message already exists.
  If it exists, you cannot create another PO with the same number.
  
  
  
  Use automatic number assignment:
  
  Avoid manually entering PO numbers unless necessary.
  Let the system assign the PO number automatically to prevent conflicts.
  
  
  
  Check and adjust number ranges:
  
  Use transaction SNRO or SNUM to check the number range object for Purchase Orders (usually EINKBELEG or similar).
  Ensure that the number range intervals do not overlap and that the current number is not already assigned.
  If the number range is exhausted or corrupted, create a new interval or reset the number range appropriately.
  
  
  
  Check for duplicate creation attempts:
  
  If the PO is created via an interface or batch job, verify that the process is not trying to create the same PO multiple times.
  Check logs and error queues for duplicate processing.
  
  
  
  Consult SAP Notes:
  
  Sometimes, specific SAP Notes address known issues related to PO number assignment and message WG011.
  Search the SAP Support Portal with the message number and system version.
