• What is the cause and solution for SAP error message WY168 - Enter a numerical partner number ?

  SAP Error Message:
  
  WY168 - Enter a numerical partner number
  
  Cause:
  This error occurs when a partner number field in a partner function assignment or partner determination procedure expects a numerical value, but the input provided is either non-numeric (contains letters or special characters) or empty.
  In SAP, partner numbers are often defined as numeric fields in customer/vendor master data or partner determination procedures. If the system expects a numeric partner number and the user enters an alphanumeric or blank value, the system throws this error.
  
  When does it typically occur?
  
  During sales document processing (e.g., sales order, delivery, billing) when assigning partners.
  When maintaining partner functions in customer/vendor master or in partner determination procedures.
  When entering partner numbers manually or via data upload where the partner number field is expected to be numeric.
  
  
  Solution:
  
  
  Check the Partner Number Input:
  
  Ensure that the partner number entered is strictly numeric.
  Remove any alphabetic characters, spaces, or special characters.
  
  
  
  Verify Partner Number Field Definition:
  
  Confirm that the partner number field in the relevant configuration or master data is defined as numeric.
  If alphanumeric partner numbers are required, the field definition or partner determination procedure might need adjustment.
  
  
  
  Data Correction:
  
  Correct the partner number in the master data or transactional document.
  If data is uploaded via interfaces or batch jobs, validate the source data to ensure numeric partner numbers.
  
  
  
  Check Partner Determination Procedure:
  
  Review the partner determination procedure configuration to ensure it aligns with the expected partner number format.
  
  
  
  Consult SAP Notes / Documentation:
  
  Sometimes, specific SAP Notes address partner number format issues in certain modules or versions.
