Variable and Fixed Overhead Absorption 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, I start by creating a new Work Center that I have named “FIXED OVERHEAD”. I have set the Direct Unit Cost to 10.00 and the Unit cost Calculation to “Units”.

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

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

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

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