  SAP Error Message: WG355
  Message Text:
  
  Supplier service level &3 % for supplier &1, plant &2 greater than &4 %
  
  Meaning / Cause
  This message occurs when the supplier service level maintained in the system for a particular supplier and plant combination exceeds a predefined maximum threshold.
  
  Supplier service level is a percentage value that indicates the reliability or performance level of a supplier.
  The system has a configured maximum allowed service level percentage.
  If the entered or calculated service level for a supplier at a specific plant exceeds this maximum allowed value, the system issues this warning or error message.
  
  This is typically a control mechanism to avoid unrealistic or incorrect service level values being maintained in the system.
  
  Where It Occurs
  
  In Purchasing or Supplier Evaluation related transactions.
  When maintaining or updating supplier master data or supplier evaluation data.
  During automatic calculations or updates of supplier service levels.
  
  
  Cause Details
  
  The service level value for the supplier &1 at plant &2 is &3 %.
  The maximum allowed service level configured in the system is &4 %.
  Since &3 % > &4 %, the system flags this as an error or warning.
  
  
  Solution / How to Fix
  
  
  Check the configured maximum service level:
  
  The maximum allowed service level is usually set in customizing.
  Path (example):
  
  SPRO -> Materials Management -> Purchasing -> Supplier Evaluation -> Define Service Level Limits
  Verify the maximum allowed service level percentage.
  
  
  
  Verify the supplier service level data:
  
  Check the supplier service level maintained for the supplier &1 and plant &2.
  Transaction codes like ME61 (Maintain Vendor Evaluation), ME6H (Vendor Evaluation: Display), or supplier master data transactions may be used.
  
  
  
  Adjust the service level:
  
  If the service level is incorrectly high, correct it to a realistic value within the allowed range.
  If the service level is correct and should be higher than the current maximum, consider increasing the maximum allowed service level in customizing.
  
  
  
  Recalculate or update supplier evaluation:
  
  After correction, recalculate supplier evaluation if necessary.
  
  
  
  
  Additional Information
  
  Supplier Service Level is a key metric in supplier evaluation and procurement performance.
  Maintaining realistic and accurate service levels helps in better supplier management and procurement planning.
  The maximum allowed service level is a system control to prevent data entry errors or unrealistic values.
  If you frequently encounter this message, review the business process and thresholds for supplier evaluation.
