Forum Post: RE: For a condition how I Assign Unit Price:=0 in Sales Order's Line

Write the below two line of code at the very end of the No. Field's OnValidate trigger and test you might see what you were looking for by crossing 1 level. There is a function call at the same trigger "UpdateUnitPrice(FIELDNO("No."));" just debug it and add your conditional assignment "Order Status" check then assign the values. "Unit Price":=0; Quantity:=15;
