• What is the cause and solution for SAP error message WRF_AT149 - System error: No supply source assigned to recipients (AT &1, &2) ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_AT149 System error: No supply source assigned to recipients (AT &1, &2)
  
  Cause:
  This error occurs in SAP when the system tries to determine a supply source for a recipient (such as a plant or location) during a supply chain or warehouse process (e.g., in Advanced Planning, Warehouse Management, or Transportation Management), but no supply source has been assigned or maintained for the recipient.
  
  &1 and &2 are placeholders for specific values, typically representing the recipient and the relevant object (e.g., plant, storage location, or transportation lane).
  The system cannot find a valid supply source (like a supplying plant, vendor, or warehouse) for the recipient in the master data or configuration.
  This often happens in scenarios involving stock transfer, replenishment, or distribution where the system needs to know from where the goods should be supplied.
  
  
  Typical Scenarios:
  
  In Transportation Management (TM), when determining the source of goods for a delivery or shipment.
  In Advanced Planning and Optimization (APO) or Supply Chain Management (SCM) during supply planning.
  In Warehouse Management (WM) or Extended Warehouse Management (EWM) when assigning supply sources for stock movements.
  When using stock transport orders or inter-plant stock transfers without proper supply source configuration.
  
  
  Solution:
  
  
  Check Supply Source Assignment:
  
  Verify that the recipient (plant, storage location, or customer) has a supply source assigned in the relevant customizing or master data.
  For example, in Transportation Management, check the Transportation Lane configuration (transaction /SCMTMS/TRANSP_LANE) to ensure that the supplying plant/vendor is assigned to the receiving plant/customer.
  
  
  
  Maintain Supply Source in Master Data:
  
  In Material Master or Plant Master, ensure that the supply source is maintained.
  In Vendor Master or Customer Master, check if the supply source relationships are properly defined.
  
  
  
  Check Configuration in Supply Chain Planning:
  
  In APO or SCM, check the Supply Network Planning settings.
  Ensure that the supply source is assigned to the recipient location in the supply network.
  
  
  
  Review Stock Transport Order or Delivery Document:
  
  If the error occurs during document processing, verify that the supplying plant is correctly specified.
  Check if the stock transport order or delivery document has the correct source and destination.
  
  
  
  Update or Create Supply Source:
  
  If missing, create the necessary supply source assignment.
  For example, in TM, create or adjust transportation lanes to include the correct supply source.
  
  
  
  Check User Exits or Enhancements:
  
  If custom logic is used to determine supply sources, verify that it correctly handles all cases.
