Example of 'Finite capacity' on Resources in AX 2012

In this post the we will look at behavior of 'Finite capacity' check box on 'Resources' form. We will create two new resources one with finite capacity and another without it. We will then assign these resources to the route operations one for each resource, and assign run time to them. We will create production orders and schedule them to see the effect on the resources' capacity reservations.

1. Create two new resources.

1. Resource: #0001, Finite capacity: Unchecked

2. Resource: #0002, Finite capacity: Checked

2. Create a route with two operations assigning run time of 8 hours and 4 hours respectively.

3. Assign first resource to first operation and second resource to the second operation in the resource requirements section.

4. Assign the route to a production item.

5. Now create two production orders, run 'Estimate' and then run 'Schedule jobs' for each of them. Make sure it is run on same date (E.g. today's date)

6. For both resources click 'Capacity load' button.

For first resource having finite capacity unchecked note that the scheduling engine has reserved the 8 hours run time  for both the production orders (operation 10) on the same date and hence overbooked the 8 hour capacity of one day which is defined in the standard calendar assigned to the resources.

For the second resource having finite capacity checked note that the scheduling engine hasn't overbooked the capacity, rather it has reserved the next available 8 hours (next day in this case) because of the finite capacity.
