Using calendars in Microsoft Dynamics AX for purchasing
You might call this an orphan topic for companies managing purchasing schedules with Microsoft Dynamics AX 2012 and Dynamics 365 for Operations (AX7), but it is nonetheless quite important. Miscalculating delivery dates on your purchases always is, particularly in make-to-order and just-in-time manufacturing and distribution.
Some unexpected behavior exists in Dynamics AX with calendars and purchase orders, which I discovered this at a recent engagement with a distributor.
When working with resource groups and resources in Dynamics AX, the calendar is a mandatory field. But in purchasing where calendars certainly have an impact, they don't seem to be mandatory anywhere.
It is time to find out how calendars work when working with (planned) purchase orders.
