• What is the cause and solution for SAP error message WSUBST108 - Differences determined upon goods receipt for purchase order &1 ?

  Certainly! Here's a detailed explanation for the SAP error message WSUBST108: Differences determined upon goods receipt for purchase order &1:
  
  Error Message
  WSUBST108: Differences determined upon goods receipt for purchase order &1
  
  Cause
  This message occurs during the goods receipt (GR) process for a purchase order (PO) when the system detects differences between the expected and actual quantities or values. These differences can be related to:
  
  Quantity differences: The quantity received is different from the quantity ordered or expected.
  Price differences: The price on the PO differs from the invoice or the valuation price.
  Valuation differences: The value of the goods received differs from the expected value due to price changes or exchange rate differences.
  Tolerance limits exceeded: The differences exceed the predefined tolerance limits set in the system for GR/IR (Goods Receipt / Invoice Receipt) account postings.
  
  
  Explanation
  When you post a goods receipt against a PO, SAP compares the received quantity and value with the PO data. If differences are found, SAP checks if these differences are within the allowed tolerance limits. If the differences exceed these limits, the system issues this message to alert the user.
  
  Solution / How to Resolve
  
  
  Check the Differences:
  
  Review the quantity and value differences in the goods receipt document.
  Use transaction MB03 (Display Material Document) or MIGO to check the details of the GR.
  Compare the PO data (ME23N) with the goods receipt data.
  
  
  
  Check Tolerance Limits:
  
  Tolerance limits for GR/IR differences are maintained in transaction OMR6.
  These limits include:
  
  Quantity tolerance (%)
  Price tolerance (%)
  Value tolerance (absolute amount)
  
  
  If the differences are within tolerance, the system allows posting without error.
  If the differences exceed tolerance, you need to either adjust the tolerance or correct the data.
  
  
  
  Adjust Tolerance Limits (if appropriate):
  
  If business processes allow, increase the tolerance limits in OMR6.
  Be cautious: increasing tolerance limits too much can lead to accounting discrepancies.
  
  
  
  Correct the Purchase Order or Goods Receipt:
  
  If the differences are due to incorrect data entry, correct the PO or the GR.
  For example, if the quantity received is wrong, post a reversal and re-post the correct quantity.
  If the price is incorrect, check with purchasing or vendor to correct the PO or invoice.
  
  
  
  Post Invoice Correctly:
  
  Sometimes differences arise because the invoice price differs from the PO price.
  Ensure that the invoice is posted correctly and matches the PO or GR data.
  
  
  
  Consult Accounting / Purchasing:
  
  If differences are legitimate (e.g., price changes, partial deliveries), coordinate with accounting and purchasing departments to handle the differences properly.
