• What is the cause and solution for SAP error message WP600 - No open PO for GR found, material &, plant & ?

  The SAP error message:
  WP600 No open PO for GR found, material & , plant &
  typically occurs during the Goods Receipt (GR) process in SAP MM (Materials Management) when the system cannot find an open Purchase Order (PO) for the specified material and plant.
  
  Cause:
  
  No open PO exists for the material and plant combination entered during the GR.
  The PO might be already fully delivered or closed.
  The PO might be created for a different plant or material.
  The PO might be blocked or not released.
  The GR is being attempted for a material that was not ordered via PO (e.g., direct consumption or stock transfer).
  The user might have entered incorrect material or plant data during the GR.
  
  
  Solution:
  
  
  Check the Purchase Order:
  
  Verify that there is an open PO for the material and plant.
  Use transaction ME23N to display the PO and check:
  
  PO status (should be released and not blocked).
  Quantity ordered vs. quantity already delivered.
  Plant and material number correctness.
  
  
  
  
  
  Check the Delivery Schedule:
  
  Confirm that the PO has open quantities for GR.
  If the PO is fully delivered, no further GR is possible.
  
  
  
  Verify the GR Process:
  
  Ensure you are using the correct PO number during the GR.
  Confirm the material and plant entered during GR match the PO.
  
  
  
  If no PO exists:
  
  Create a PO for the material and plant.
  Or, if the material is to be received without PO (e.g., stock transfer), use the appropriate transaction or process.
  
  
  
  Check for Blocked or Incomplete POs:
  
  Release or unblock the PO if necessary.
  
  
  
  Consult with Purchasing Department:
  
  Confirm if the PO was created and is valid for the GR.
