  SAP Error Message: WY159
  Text: Partner functions for VSR &1 and plant &2 already created
  
  
  Cause:
  This error occurs when you try to create or assign partner functions for a Vendor Service Request (VSR) and plant combination that already has partner functions assigned. In other words, the system detects that partner functions for the specified VSR number and plant already exist, and it does not allow duplicate partner function entries for the same combination.
  This typically happens during the creation or update of vendor service requests or related master data where partner functions are maintained.
  
  Explanation:
  
  VSR (Vendor Service Request): A document or master data entity related to vendor services.
  Partner Functions: Roles assigned to business partners in a document or master data (e.g., ordering address, invoicing party).
  Plant: Organizational unit in logistics representing a manufacturing location or warehouse.
