Using calendars in Microsoft Dynamics AX for purchasing

November 14 2016

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.

Hi Evert, Great article as always :) Your contributions are really valuable for any production and distribution functional consultant out there. Technically speaking calendar is not a mandatory field on neither resource nor resource group. But that is, of course, will make them unusable during job scheduling of production orders (with finite capacity option either on or off). I would compare this situation to assigning resource group to a resource: the assignment is not required when resource is created but the system would not be able to find a resource when operation or job scheduling is executed.

Привет! Я был в Львове 2 года назад. Очень понравился город. Я голландский. У меня от молодости сильная тяга к славианским културам. Я часто бываю в Польше, в Украине и в России.
