Logi behind the calculation of Purchase Lead Time and Latest Order Date
When the lead times are set as follow: How the “Purchase Lead Time” is calculated? How the “Latest Order Date” is calucated in Purchase Requisition Line (Distribution calendar is 5-days per week, assuming no exceptions) Supplier Manufacturing Lead Time External Transport Lead Time Transport Lead Time Internal Delivery Lead Time Inspection Lead Time 280 0 0 4 20 Purchase Lead Time = Supplier Manufacturing Lead Time + External Transport Lead Time + Transport Lead Time + Internal Delivery Lead Time + Inspection Lead. Time When calcualting the Lead Time, the calendar is not relevant therefore the Purcahse Lead Time is 304 days in this scenario. Then when a Purchase Requisition Line is created for this part with “Wanted Receipt Date” as 2024-10-04, the “Latest Order Date” is calculated as 2023-11-27. The number of calendar days between 2023-11-27 and 2024-10-04 is 312 days not 304 days. There is a difference due to the used calendars. First 280 days are calculated considering 7 working days
