  SAP Error Message WG116
  Message Text:
  
  No external supply source determined for requirement no. &, mat. no. &
  
  Meaning / Cause
  This error occurs during the availability check or requirements planning process in SAP when the system tries to find an external procurement source (like a purchase order or planned order from an external vendor) for a particular requirement but fails to find any.
  In other words, for the given requirement number and material number, the system cannot determine any external supply source to fulfill the demand.
  Common causes include:
  
  No purchase requisition, purchase order, or planned order exists for the material to cover the requirement.
  The material master is not maintained correctly for external procurement.
  The procurement type in the material master is not set to allow external procurement.
  The source list or info records are missing or not maintained properly.
  The requirement is created but no corresponding supply elements (like purchase orders or planned orders) are available or linked.
  The MRP run did not generate procurement proposals for the requirement.
  The availability check settings or scope of check do not consider external procurement sources.
  
  
  Where It Occurs
  
  During availability check (e.g., in sales order processing, production order creation).
  During MRP run or requirements planning.
  When confirming or processing requirements that need to be fulfilled externally.
  
  
  Solution / How to Fix
  
  
  Check Material Master Procurement Settings:
  
  Go to transaction MM03 ? Purchasing view.
  Verify that the Procurement Type is set to allow external procurement (e.g., 'F' for external procurement).
  Check if the MRP type and other relevant fields are correctly maintained.
  
  
  
  Check Source List and Info Records:
  
  Use transaction ME01 / ME03 to check if a valid source of supply exists for the material.
  Ensure that the source list is valid for the plant and the procurement type.
  
  
  
  Check Purchase Requisitions / Purchase Orders:
  
  Verify if there are any open purchase requisitions or purchase orders for the material that can cover the requirement.
  If none exist, create purchase requisitions or planned orders to cover the demand.
  
  
  
  Run MRP:
  
  Execute MRP (transaction MD01, MD02, or MD03) for the material and plant.
  Check if MRP generates procurement proposals (planned orders or purchase requisitions).
  If MRP does not generate proposals, check MRP parameters and lot sizing.
  
  
  
  Check Availability Check Settings:
  
  Review the scope of check in the availability check configuration (transaction OVZ9).
  Ensure that external procurement sources are included in the availability check.
  
  
  
  Check Requirement and Supply Elements:
  
  Analyze the requirement number and material number mentioned in the error.
  Use transaction MD04 (Stock/Requirements List) to see the current stock, requirements, and procurement proposals.
  Confirm that there are supply elements to cover the requirement.
  
  
  
  If using subcontracting or special procurement types:
  
  Verify that the special procurement keys and related settings are correctly maintained.
