  SAP Error Message: WY104 - Partner function & defined for hierarchies
  
  
  Cause:
  The error message WY104 occurs when you try to assign or use a partner function that is not defined or not allowed for the specific hierarchy type in the SAP system.
  In SAP, partner functions are used to define roles of business partners in a business transaction (e.g., sold-to party, ship-to party, payer, etc.). When hierarchies are involved (such as customer hierarchies or vendor hierarchies), only certain partner functions are allowed or defined for those hierarchies.
  This error typically arises in scenarios involving:
  
  Customer or vendor hierarchies in Sales and Distribution (SD) or Financial Accounting (FI).
  Assigning a partner function to a hierarchy node where that partner function is not configured.
  Master data maintenance or transaction processing where the system checks partner function validity against hierarchy definitions.
