  VPD029 - Select a partner
  
  Cause:
  The error message VPD029 - Select a partner typically occurs in SAP when a required partner function has not been assigned or selected in a business transaction or master data record. This is common in processes involving partner determination, such as sales orders, deliveries, billing documents, or customer/vendor master data, where the system expects a partner (e.g., sold-to party, ship-to party, payer) to be specified but none has been entered.
  
  When does it occur?
  
  During sales order creation or processing, if a mandatory partner function is missing.
  In partner determination procedures where the system expects a partner but none is assigned.
  In master data maintenance (e.g., customer or vendor master) when partner roles are incomplete.
  In delivery or billing documents where partner roles are required.
  
  
  Solution:
  
  
  Check Partner Determination Procedure:
  
  Verify the partner determination procedure assigned to the transaction (e.g., sales document type).
  Ensure that the mandatory partner functions are correctly defined and assigned.
  
  
  
  Assign the Required Partner:

  For example, in a sales order, ensure that the Sold-to party, Ship-to party, Payer, and Bill-to party are correctly assigned.
  
  
  
  Maintain Partner Functions in Master Data:
  
  Check the customer or vendor master data to ensure that the necessary partner functions are maintained.
  Use transaction codes like VD03 (Display Customer), VD02 (Change Customer), or XK03 (Display Vendor) to verify partner assignments.
