not equal the reduced purchase order quantity.
In the purchase order &V3&, item &V4&, the order unit was changed. This
may mean that the quantity to be allcoated does not equal the quantity
ordered.

• What is the cause and solution for SAP error message WRF_AT104 - Alloc. table &1, item &2; order-optimized qty not equal to reduced PO qty ?

  Certainly! Here's a detailed explanation of the SAP error message:
  
  SAP Error Message:
  WRF_AT104 Alloc. table &1, item &2; order-optimized qty not equal to reduced PO qty
  
  Meaning / Cause:
  This error occurs during the allocation or confirmation process in SAP, typically in the context of production order confirmations or goods movements related to purchase orders (POs). The system detects a mismatch between:
  
  The order-optimized quantity (the quantity planned or optimized for the production order or process order), and  
  The reduced PO quantity (the quantity reduced or confirmed against the purchase order).
  
  In other words, the quantity that the system expects to confirm or allocate based on the production order does not match the quantity that has been reduced or confirmed on the purchase order side.
  This inconsistency can arise due to:
  
  Partial confirmations or goods receipts that do not align with the planned order quantities.  
  Manual changes or adjustments in quantities either in the production order or purchase order.  
  Incorrect or incomplete data transfer between production order and purchase order during confirmation or goods receipt.  
  System rounding differences or unit of measure inconsistencies.  
  Allocation table entries (&1 = allocation table name, &2 = item number) that are out of sync or corrupted.
  
  
  Where it occurs:
  
  During production order confirmations (e.g., in CO11N or similar transactions).  
  During goods receipt postings against purchase orders linked to production orders.  
  In processes involving order-related procurement or subcontracting scenarios.
  
  
  Solution / How to fix:
  
  
  Check the quantities:
  
  Verify the quantities on the production order and the purchase order item.  
  Ensure that the confirmed or received quantities match the planned or optimized quantities.
  
  
  
  Review allocation tables:
  
  The error references an allocation table (&1) and item (&2). Check the allocation entries for inconsistencies or incorrect data.  
  Use transaction codes like CO03 (Display Production Order) or ME23N (Display Purchase Order) to review details.
  
  
  
  Adjust quantities if necessary:
  
  If there are discrepancies, adjust the quantities in the production order or purchase order to align them.  
  This might involve reversing incorrect confirmations or goods receipts and reposting with correct quantities.
  
  
  
  Check unit of measure (UoM):
  
  Confirm that the units of measure are consistent between the production order and purchase order.  
  Conversion errors can cause quantity mismatches.
  
  
  
  Check for rounding differences:
  
  Sometimes rounding differences in quantity calculations can cause this error.  
  Adjust tolerances or rounding settings if applicable.
  
  
  
  Re-run confirmation or goods receipt:
  
  After corrections, try to re-run the confirmation or goods receipt process.
  
  
  
  Consult SAP Notes:
  
  Search for SAP Notes related to WRF_AT104 for any known bugs or patches.
  
  
  
  
  Additional Information:
  
  Allocation tables in SAP are used to manage the relationship between production orders and purchase orders, especially in subcontracting or external procurement scenarios.  
  This error is a consistency check to prevent incorrect postings that could lead to inventory or financial discrepancies.  
  Always ensure that master data (material master, BOM, routing) and transactional data are consistent.
