Variable and Fixed Overhead Absorption in Microsoft Dynamics NAV

ArcherPoint How-To Blog: Step-by-step instructions on how to perform specific tasks in Microsoft Dynamics NAV

There are Dynamics NAV clients that would like to separate Variable and Fixed Overhead.

If we look at a Dynamics NAV Work Center Card, we see that we can put in a Direct Unit Cost and an Indirect Cost % or Overhead Rate. However, there is no place to indicate if this cost is Variable or Fixed.

To accommodate a Fixed Cost Component to the Cost of Production, we start by creating a new Work Center that I have named “FIXED OVERHEAD”.

We have set the Direct Unit Cost to 10.00 and the Unit cost Calculation to “Units”.

We created a new General Product Posting Group called FIXED OH and pointed the Direct Cost Applied Account to a new General Ledger Account that we also called FIXED OH.

We then added a Parallel Operation to the Routing Lines using the new FIXED OVERHEAD Work Center.

To test it, we created a Released Production Order that calls for the routing to which I added the parallel step.

After we have changed the Production Order to the finished status, we can see in the General Ledger that it reflects the appropriate Debit to the WIP account and to the Fixed Overhead Absorbed account.
