• What is the cause and solution for SAP error message VMP_MSG159 - Non-visual qty of &1 for material &2 doesn't match total source qty of &3 ?

  The SAP error message VMP_MSG159 indicates a discrepancy between the non-visual quantity of a material and the total source quantity. This typically occurs in the context of inventory management or material handling processes, particularly when dealing with batch management or handling units.
  Cause:
  The error arises when the system detects that the non-visual quantity (the quantity that is not displayed visually in the system) for a specific material does not match the total source quantity that is expected. This can happen due to several reasons, including:
  
  Data Entry Errors: Incorrect quantities may have been entered during the creation or processing of a document.
  Batch Management Issues: If the material is batch-managed, discrepancies can occur if the batch quantities do not align with the expected totals.
  Handling Unit Issues: If handling units are involved, the quantities in the handling units may not match the expected quantities in the inventory.
  Inventory Adjustments: Manual adjustments to inventory levels that are not properly reflected in the system can lead to mismatches.
  Configuration Issues: Incorrect configuration in the material master or inventory management settings can also lead to this error.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  Verify Quantities: Check the quantities for the material in question. Ensure that the non-visual quantity matches the total source quantity.
  Review Document Flow: Look at the document flow related to the material movement. Ensure that all related documents (e.g., goods receipts, goods issues) are correctly processed.
  Check Batch and Handling Units: If the material is batch-managed or involves handling units, verify that the batch quantities and handling unit quantities are correct and consistent.
  Adjust Inventory: If discrepancies are found, you may need to perform inventory adjustments to correct the quantities in the system.
  Consult Configuration: If the issue persists, review the configuration settings for the material in the material master and inventory management to ensure they are set up correctly.
  Run Reports: Use inventory reports to identify any discrepancies in stock levels and investigate further.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like MB52 (List Warehouse Stocks on Hand) or MB5B (Stocks for Posting Date) to analyze stock levels.
  Batch Management: If applicable, familiarize yourself with batch management processes in SAP, including how to manage and track batches.
  Handling Units: Understand how handling units work in SAP and how they can affect inventory quantities.
  SAP Notes: Check for any relevant SAP Notes or documentation that may address specific issues related to this error message.
