  SAP Error Message: WY075
  Text: Partner function & not assigned to schema &
  
  Cause:
  This error occurs when the system tries to process a partner function in a business transaction (such as sales order, delivery, billing, etc.) but cannot find the partner function assigned to the specified partner determination procedure (also called partner schema).
  In other words, the partner function you are trying to use is not maintained or assigned in the partner determination procedure/schema that is active for the document or process.
  
  Explanation:
  
  Partner function: Defines the role of a business partner in a transaction (e.g., Sold-to party, Ship-to party, Payer, Bill-to party).
  Partner determination procedure/schema: A configuration that controls which partner functions are relevant and how they are determined for a particular business object (sales order, delivery, billing document, etc.).
  
  If the partner function is missing in the partner determination procedure, the system cannot assign or find the partner, leading to this error.
  
  Where it typically occurs:
  
  Sales and Distribution (SD) module during sales order creation or processing.
  Delivery processing.
  Billing document creation.
  Any process involving partner determination.
  
  
  How to find the relevant partner determination procedure:
  
  For sales orders: Check the sales document type and sales area.
  For deliveries: Check the delivery type.
  For billing: Check the billing type.
  
  
  Solution:
  
  
  Check the partner determination procedure/schema:
  
  Go to the customizing transaction for partner determination:
  
  For sales orders: SPRO ? Sales and Distribution ? Basic Functions ? Partner Determination ? Set Up Partner Determination.
  For deliveries: Similar path under Delivery.
  For billing documents: Under Billing.
  
  
  
  
  
  Verify the partner determination procedure assigned to the document type:
  
  For sales orders: Check the sales document type configuration to see which partner determination procedure is assigned.
  
  
  
  Check if the partner function is assigned to the partner determination procedure:
  
  In the partner determination procedure, verify that the partner function (e.g., SH for Ship-to party, PY for Payer) is included.
  If missing, add the required partner function to the procedure.
  
  
  
  Maintain partner function details:
  
  Ensure that the partner function is properly maintained with the correct partner number in the master data or document.
  
  
  
  Test the transaction again:
  
  After making the necessary configuration changes, retry the transaction to confirm the error is resolved.
  
  
  
  
  Additional Notes:
  
  Sometimes, this error can also occur if a custom partner function was introduced but not properly assigned to the partner determination procedure.
  Partner determination procedures are client-specific and must be maintained carefully to reflect business requirements.
  Always transport changes from development to quality and production systems following your change management process.
