Hi, 

 

I have an issue with the creation of purchase requisitions. Some requisitions are automatically created with “latest order date” in the past. 

 

It seems like it sabstracts the Supplier Manufacturing Lead Time as weekdays (5) and not calendar days (7).

For a part #7513, the supplier manufacturing lead time is 10 days. 

For this supplier, the external transport, the transport, the internal transport and safety lead times are 0. 

 

So the “latest order date” should be equal to : Wanted receipt date - Supplier Manufacturing Lead time. 

 

But, a purchase requisition line was created with “wanted receipt date = 08/04/2026” and “latest order date = 20/03/2026”

 

Am I missing something ?

This is the ‘help’ description.  I think the Calendar against your site/company are relevant in determining what are working days and what are not.

Thank you for your answer, but my understanding was that the “Manufacturing lead time from the supplier” was not expressed in working days as there is no calendar for supplier ?

As I understand it definition of Supplier Manufacturing Leadtime is 

The supplier manufacturing lead time is measured in supplier calendar days, which only includes workdays. If no supplier calendar is defined, manufacturing lead time is measured in calendar days, which includes weekends and holidays. The information is retrieved from the combination of supplier and purchase part.

If you wish you, it is possible to define a supplier calendar. But I would have though it is an admin heavy data setup.

This might explain some of the gap in dates. I have a defined calendar for the supplier, which might turn the Supplier Manufacturing Lead time into working days. 

If I am not wrong, the wanted receipt date is calculated with the purchase lead time which is in calendar days ? 

 

Which would mean that it adds the purchase lead time in calendar days and then substract the same amount of days but in working days.
