• What is the cause and solution for SAP error message GTCN_MESSAGE121 - Quantity of supplied documents must be equal to the release quantity ?

  The SAP error message GTCN_MESSAGE121 indicates that there is a mismatch between the quantity of documents supplied and the release quantity in a transaction. This error typically occurs in the context of logistics, procurement, or inventory management processes, particularly when dealing with goods receipts, deliveries, or similar transactions.
  Cause:
  
  
  Mismatch in Quantities: The most common cause is that the quantity of documents (e.g., delivery notes, invoices) being processed does not match the expected release quantity. For example, if you are trying to process a goods receipt for 100 units but only have documentation for 80 units, this error will occur.
  
  
  Incorrect Document Entry: There may be an error in the data entry where the quantities were incorrectly entered or recorded.
  
  
  Incomplete Documentation: The necessary documentation for the full quantity may not have been provided or may be missing.
  
  
  System Configuration Issues: In some cases, the configuration settings in SAP may not align with the business processes, leading to discrepancies in expected quantities.
  
  
  Solution:
  
  
  Verify Quantities: Check the quantities in the documents you are trying to process. Ensure that the total quantity of supplied documents matches the release quantity.
  
  
  Adjust Document Entries: If there is an error in the quantity entered, correct it to match the expected release quantity.
  
  
  Complete Documentation: Ensure that all necessary documentation is available and correctly reflects the quantities being processed.
  
  
  Consult with Stakeholders: If there are discrepancies, consult with relevant stakeholders (e.g., warehouse, procurement) to clarify the correct quantities and resolve any issues.
  
  
  Review Configuration: If the issue persists, review the system configuration settings related to the transaction to ensure they are set up correctly.
  
  
  Use Transaction Codes: Utilize relevant transaction codes (e.g., MIGO for goods movements) to check the status of the documents and quantities involved.
  
  
  Related Information:
  
  
  Transaction Codes: Familiarize yourself with transaction codes like MIGO (Goods Movement), MIRO (Invoice Verification), and VL01N (Create Outbound Delivery) as they are often involved in processes that may trigger this error.
  
  
  SAP Notes: Check SAP Notes and documentation for any known issues or patches related to this error message.
  
  
  User Training: Ensure that users involved in the process are adequately trained on how to enter and manage quantities in SAP to minimize errors.
