Setting up a fixed material overhead per part in Costing

Hi,

We’re trying to set up a material overhead with a fixed cost per part in the structure - the idea is that each issue shall generate a posting with that cost, and that there should be a fixed cost per part rolled up to the next level. E g if the overhead is 100, and there are two parts in the structure of the manufactured part, the cost would be 200.

Our overhead generates correctly when the material is issued on the shop order. But we cannot get it to show in the Part Cost. The documentation seems to indicate that it should be possible, but we have tried several combinations with no success so far. Is this possible, and how should the overhead be set up in such a case?

Tested in 25.2.3

Hejsan Kenneth,

This is a bug, it has worked in the past. You should raise a support ticket.

And by the way, when testing in the page below I got it to work, but that is a separate cost rollup.

On one of my immediate components for the top part T470S I have fixed Material OH cost defined.

Anyway, please enter a support ticket, and we will have it fixed.

Best Regards,

Mats

Hi @KennethP the material overhead cost bucket must be in the cost template for the parts for which their OH will roll-up to the parent when issued. This overhead bucket is visible in the Cost Bucket details of the parent, not at the component level.

Component MW-MFG-400 uses template AGG01.

Template AGG01 contains a 20% material OH cost bucket. Note above how this cost bucket is not displayed in the Cost Bucket Detail of the component itself.

At the parent part level, using the standard cost template M-110, this overhead bucket is displayed, as this is the level at which the cost is applied.

Hi Matt,

And thanks for your effort, with pictures and all :-)

If I set up an overhead with a factor (a percentage of the cost) as it looks like you did, that works for me too. The key here though is that the user wants a fixed overhead that would be paid once for each material in the structure, not based on its cost. So my cost bucket and element for the overhead looks like below. It’s also included in the cost template of the purchased part.

It does not roll up to its parent as the percentage overhead does. I’ve tried one based on 501 part specific overhead too, but that does not roll up either. So I’m a bit puzzled - is it a true limitation, a bug or have I just missed some detail that would make it work? It generates postings at transaction time, but it does not show up in part costing.

Our community AI indicates that it would in fact be possible, mainly supported by the documentation I guess. I also tried looking into some code and it really looks like there is support for fixed material overheads. But it did not help me finding out how. Next step would be a thorough debugging/tracing session but that’s heavy artillery.
