How to Place D365 Purchase Orders Within Lead Time

In Dynamics 365 (D365), a new parameter was added to the master plan that controls whether it is possible or not to place D365 purchase orders within lead time.

D365 purchase orders

D365 purchase orders

The description of this new field is not precise. It is about the order date of the planned orders (for planned purchase) or the start date (for planned production). If I say no, the MRP will create planned orders with a start date set in the past.

If I say yes, all planned orders will have the start date set for today.

And this same field also controls the “ordering within lead time” that many companies want to be able to do. It used to be impossible. We did a customization to make this possible in AX2012. During firming, the system would apply the lead time of the item, and the Purchase order delivery date was today + lead time, no matter what the requirement date was.

With this parameter set to “No,” I can manually change the delivery date in the planned purchase order to be within lead time. When I then firm the planned Purchase order, my manually set delivery date will go to the PO.

When I change the Delivery date to an earlier date, the system will automatically change the order date. This order date can go into the past. That is precisely the point. I can order within lead time. (NOTE: the “start date” and “end date” are for planned production orders and have no meaning for planned purchase orders. However, they still move along with the delivery date and the order date.)

Please also note that you cannot change the delivery date to a date before today.

When this parameter is “yes,” I will not be able to change the delivery date on the planned purchase order to an earlier date.
