Using Both Part Revisions and Templates

[asymworks]

I'm still learning how to work best with Inventree and am not seeing the obvious "right way" (if there is one) to mix Part Templates and Revisions. There's a specific case I just came up against that illustrates one limit, but I am interested in hearing other perspectives on how to use them both together.

For my particular case, say I have a PCB Assembly, part PCB-1, which I have set up in Inventree with the complete BOM underneath it. Unfortunately Revision A of PCB-1 was manufactured with shorted traces. I create Rev B of PCB-1, also with a full BOM, in Inventree with the fixed artwork. I could easily make an external Build Order to buy a new set of PCB-1 Rev B boards, but as it turns out I could take a Rev A board and simply cut a trace, making it equivalent to a PCB-1 Rev B board. Great - I can save some money and time! But - Inventree does not let me create a Build Order to make a Rev B board out of a Rev A, because the Rev B BOM still reflects the whole assembly and does not let me kit in a Rev A board instead.

The way I would imagine doing this in Inventree, is making PCB-1 Rev B a Template part, as a Revision of PCB-1 Rev A. There could be two variants - one with the complete BOM and which could be procured with an External Build Order, and a "PCB-1-B-MAKE-FROM-A" part which has a single Rev A part on its BOM. Then I could issue an internal Build Order for that "MAKE-FROM" part, consume Rev A boards, and create Rev B boards. But I don't think I can do this because Templates can't have Revisions per the documentation.

I could also set up "PCB-1-B-MAKE-FROM-A" as a standalone part, create the Build Order, and end up with PCB-1-B-MAKE-FROM-A parts in inventory. But from there I also don't see a way to re-identify those parts as normal PCB-1 Rev B parts within Inventree. It could be done manually by removing stock from the former and adding stock in the latter, but I lose traceability, which isn't a dealbreaker but I like having things clearly documented within the tool if possible.

Curious if anyone has encountered a similar problem, or just in general how others are combining Templates and Revisions in their workflows since I don't have a good vision for it.

I think you are making this more complex than it needs to be. Destroy the stock that you need to rework and add a note. Create stock for the new revision with a note.
Modeling a one-off action into your permanent BOM graph sounds like needless effort.

There is no built-in way to handle this in InvenTree. If you really want to trace this a custom plugin could probably do the required transformations and add stock tracking entries that note the action.
