  Caution: partner determination procedure will change from &2 to &3 on &1
  
  1. Cause of the Message
  This message is a warning (caution) that appears during the processing of a business transaction (such as sales order, delivery, billing, etc.) when the system detects that the partner determination procedure assigned to the document or item is going to change.
  
  &1 = Document or item number (e.g., sales order number)
  &2 = Current partner determination procedure
  &3 = New partner determination procedure that will be assigned
  
  The partner determination procedure controls how business partners (sold-to party, ship-to party, payer, etc.) are determined and assigned in the document.
  Why does this happen?  
  
  The partner determination procedure is assigned based on certain criteria such as sales area, document type, customer master data, or material master data.
  If any of these criteria change or if the system finds a different procedure more appropriate during document processing, it will switch the procedure.
  This message warns the user that the partner determination procedure will be changed automatically by the system.
  
  
  2. When Does This Occur?
  
  During sales order creation or change.
  During delivery or billing document creation.
  When master data or customizing settings related to partner determination have been changed.
  When the system re-evaluates the partner determination procedure due to changes in document data or configuration.
  
  
  3. Implications
  
  The change in partner determination procedure may lead to different partners being assigned or partner functions being handled differently.
  It may affect partner-related processes such as shipping, billing, or communication.
  Usually, this is a caution message, not an error, so the document processing continues but with a changed partner determination procedure.
