• What is the cause and solution for SAP error message WP633 - No open PO for GR found, material &, plant & ?

  The SAP error message:
  WP633 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:
  
  There is no open (i.e., not fully delivered or closed) Purchase Order available for the given material and plant combination.
  The PO might be already fully delivered, closed, or blocked.
  The material or plant data entered during the GR does not match any open PO line items.
  The PO might be created for a different plant or material.
  The PO might be created with a different item category or delivery schedule that does not allow GR.
  The user might be trying to post a GR without referencing a PO (if the process requires PO reference).
  
  
  Solution:
  
  
  Check the Purchase Order:
  
  Verify that there is an open PO for the material and plant in question.
  Use transaction ME23N to display the PO and check:
  
  The PO status (should not be closed or fully delivered).
  The delivery schedule and quantity (ensure there is still quantity left to be received).
  The plant assigned in the PO line item matches the plant in the GR.
  
  
  
  
  
  Check the Goods Receipt Posting:
  
  Ensure you are referencing the correct PO number during the GR.
  If you are doing a GR without PO, confirm that the process allows it (e.g., for direct goods receipt or stock transfer).
  
  
  
  If PO is missing or incorrect:
  
  Create a new PO for the material and plant.
  Or correct the plant/material in the GR to match the PO.
  
  
  
  Check for Blocked or Closed POs:
  
  Sometimes POs are blocked for GR or invoicing; check the PO status.
  If blocked, unblock or create a new PO.
  
  
  
  Check User Input:
  
  Verify that the material number and plant entered during GR are correct.
  Check for typos or wrong entries.
  
  
  
  If using special procurement types or special stock:
  
  Ensure the PO and GR process is aligned with the special stock or procurement type.

  SAP Notes:
  
  Check SAP OSS notes related to WP633 for any known bugs or patches.
  
  
  Configuration:
  
  Ensure that the material master data is correctly maintained for the plant.
  Check the movement type used in GR and its configuration.
  
  
  Process:
  
  The system expects a valid PO reference for GR if the process is PO-based.
  If GR is done without PO, use appropriate movement types (e.g., 561 for initial stock upload).
  
  
  
  
  Summary:
  The error WP633 means SAP cannot find an open PO for the material and plant during GR posting. Verify the existence and status of the PO, ensure correct data entry, and create or correct the PO if necessary.
