  Error Message:
  VP445 - Partner function & is not defined at item level
  
  Cause:
  This error occurs during sales document processing (e.g., sales order, delivery, billing) when the system expects a partner function to be assigned at the item level, but it is missing or not maintained.
  
  In SAP SD (Sales and Distribution), partner functions define the roles of business partners involved in a sales document (e.g., Sold-to party, Ship-to party, Payer, Bill-to party).
  Partner functions can be maintained either at the header level or item level.
  Some partner functions are mandatory at the item level depending on the sales document type, item category, or business process.
  If the system configuration or business rules require a partner function at the item level and it is not maintained, the system throws this error.
  
  
  When does it typically occur?
  
  Creating or changing a sales document (sales order, delivery, billing document).
  Partner determination procedure expects a partner function at item level.
  Customizing or master data setup requires partner function at item level but it is missing.
  Partner determination procedure is incorrectly configured.
  
  
  Solution:
  
  
  Check Partner Determination Procedure:
  
  Go to transaction VOPA (Partner Determination).
  Check the partner determination procedure assigned to the sales document type and item category.
  Verify which partner functions are set as mandatory at the item level.
  If a partner function is mandatory at item level, ensure it is maintained in the sales document.
  
  
  
  Maintain Partner Functions at Item Level:
  
  When creating or changing the sales document, manually add the required partner function at the item level.

  Adjust Partner Determination Procedure (if applicable):

  SPRO ? Sales and Distribution ? Basic Functions ? Partner Determination ? Set Up Partner Determination Procedures
