  Certainly! Here's a detailed explanation for the SAP error message WP851:
  
  SAP Error Message: WP851
  Text: Several open purchase orders, no suitable item, material & plant &
  
  Cause:
  This error occurs during the creation or processing of a goods receipt or invoice verification when the system tries to find a suitable purchase order item for the given material and plant but fails to find one. However, there are multiple open purchase orders for the same material and plant, but none matches the criteria exactly (e.g., quantity, delivery date, or other item details).
  In other words, the system detects that there are open purchase orders for the material and plant combination, but none of the items in those POs can be assigned to the current document (e.g., goods receipt or invoice).
  
  When does it occur?
  
  During Goods Receipt (GR) against a Purchase Order (PO).
  During Invoice Verification when matching an invoice to a PO.
  When the system tries to automatically assign a PO item but cannot find a unique or suitable item.
  
  
  Typical Reasons:
  
  Multiple open POs exist for the same material and plant, but none matches the quantity or delivery date.
  The PO items are already fully delivered or invoiced.
  The material or plant data in the document does not exactly match the PO.
  The document is trying to post a quantity that exceeds the open quantity on the PO items.
  The PO items are blocked or deleted.
  The document is missing or has incorrect reference data.
  
  
  Solution:
  
  
  Check Open Purchase Orders:
  
  Use transaction ME2M or ME2L to list open purchase orders for the material and plant.
  Verify the status of these POs and their items (open quantity, delivery schedule, etc.).
  
  
  
  Verify Material and Plant Data:
  
  Ensure that the material and plant in the goods receipt or invoice document exactly match those in the PO.
  
  
  
  Check Quantities:
  
  Confirm that the quantity you are trying to post does not exceed the open quantity on the PO item.
  
  
  
  Select the Correct PO Item Manually:
  
  If the system cannot find a suitable PO item automatically, try to manually select the correct PO item during the posting.
  
  
  
  Check for PO Item Block or Deletion:
  
  Verify that the PO items are not blocked or deleted.
  
  
  
  Adjust Document Data:
  
  If the document data (material, plant, quantity) is incorrect, correct it to match the PO.
  
  
  
  Use the Correct Movement Type:
  
  Ensure the movement type used in the goods receipt is appropriate for the PO.
  
  
  
  Consult with Purchasing Department:
  
  If no suitable PO exists, coordinate with purchasing to create or modify a PO that matches the requirement.
  
  
  
  
  Additional Information:
  
  This error is related to the automatic assignment logic in SAP MM when posting goods receipts or invoice verifications.
  The system tries to find a unique PO item based on material, plant, and quantity.
  If multiple POs exist and none fits exactly, the system cannot decide which PO item to assign, hence the error.
  Sometimes, customizing or user exits can influence the assignment logic.
