Rate Only
For a Subcontracting Procurement Order Line with the Line Type field set to Rate Only, you must specify only the Procurement Rate, expressed in order currency per rate unit. You cannot specify the Quantity or the Order Amount.
You can also select the Call-Off check box and define the call-off schedule with call-off quantities and start and end dates. When a call-off schedule exists for an order line, the Application for Payment or the Certificate of Payment related process is executed from the Subcontracting Procurement Order Line Call-Off (tdpur6603m000) session level. On the call-off line, an amount can be calculated, based on the order line rate and the call-off line quantity.
The call-off quantity of the call-off lines are cumulated for the Subcontracting Procurement Order Line. Consequently, the value in the Quantity field is updated and you cannot modify this value.
