• What is the cause and solution for SAP error message WG334 - Supplier &1, plant &2, &3 percent supplier service level. No load built! ?

  The SAP error message:
  WG334 Supplier &1, plant &2, &3 percent supplier service level. No load built!
  Explanation / Cause:
  This message typically occurs in the context of SAP Supply Chain Management (SCM) or SAP Advanced Planning and Optimization (APO), specifically during the production planning or supply network planning (SNP) process.
  
  The message indicates that for the given supplier (&1) and plant (&2), the system has calculated a supplier service level of &3 percent.
  However, despite this service level, no procurement or production order (no load) has been created for this supplier and plant combination.
  This situation usually arises when the system tries to plan supply from a supplier but, due to constraints or settings, it does not generate any planned orders or purchase requisitions.
  The supplier service level percentage reflects the expected fulfillment rate from the supplier, but the system could not build any load (planned order or purchase requisition) to meet the demand.
  
  Common Causes:
  
  Planning parameters or constraints prevent the system from creating planned orders or purchase requisitions.
  Supplier or plant master data issues, such as missing or incorrect source list entries, quota arrangements, or vendor master data.
  Insufficient capacity or availability at the supplier or plant.
  Incorrect or missing procurement type or source determination settings.
  Planning horizon or lot size settings that prevent order creation.
  Service level targets set too high or conflicting with other planning parameters.
  
  Solution / How to Resolve:
  
  Check Source Determination:
  
  Verify that the supplier is correctly assigned as a source of supply for the material and plant.
  Check source list entries and quota arrangements.
  
  
  Review Planning Parameters:
  
  Check lot size, minimum order quantity, and procurement type settings.
  Adjust planning horizon or reorder point if applicable.
  
  
  Check Capacity and Availability:
  
  Ensure that the supplier or plant has sufficient capacity and stock to fulfill the demand.
  
  
  Adjust Service Level Settings:
  
  Review the service level targets and adjust if they are unrealistic.
  
  
  Check Master Data:
  
  Verify vendor master data, purchasing info records, and plant data.
  
  
  Run Planning Logs:
  
  Analyze the planning run logs to identify why no load was created.
  
  
  Consult SAP Notes:
  
  Look for SAP Notes related to message WG334 for any known issues or patches.
  
  
  
  Additional Information:
  
  This message is informational but indicates a potential planning issue that could lead to supply shortages.
  It is important to investigate and resolve the root cause to ensure that procurement or production orders are generated as expected.
  The message helps planners identify suppliers or plants where the expected service level is not translating into planned supply.
