• What is the cause and solution for SAP error message VMP_MSG309 - Source validity is mandatory ?

  SAP Error Message:
  VMP_MSG309 Source validity is mandatory
  
  
  Cause:
  This error occurs in SAP when a source validity period is missing or not maintained for a source of supply in the Vendor Management Process (VMP) or related procurement scenarios. The system requires a validity period to determine the timeframe during which the source (e.g., vendor, contract, info record) is valid and can be used for procurement or planning.
  In other words, the system expects a validity start and end date for the source of supply, and if these dates are not maintained or are incomplete, it triggers this error.
  
  When does it typically occur?
  
  When creating or changing a source of supply (e.g., info record, outline agreement, quota arrangement) without specifying validity dates.
  During procurement planning or source determination where the system checks for valid sources.
  In Vendor Managed Inventory (VMI) or Vendor Managed Procurement (VMP) scenarios where source validity is critical.
