Calculation of Order finish date in MRP

69 Views

Hi,

I can't understand the calculation of the Order finish date for Purch. Req. and Plnd. Order for the External procurment materials.

In MD04 I see that from the date of the requirement it subtracts the "float before production" (set up in the SMK of the finish good) and the GR time (set up in the Master data of the material).

But I always see that the Order finish date of the Purch. Req. and Plnd Order (the delivery date) are always anticipated also by other about two dates, before the requirement.

Why?
