North star: Have InvenTree manage files and their usage within the system in a way that different PDM, VCS and file sharing systems can be integrated.

This means:

• Pull data from external systems
• Push data to external systems
• Diff state between systems and InvenTree
• Map / extract data from systems to InvenTree
• Map / convert data from InvenTree for systems

This needs flushing out and could be a candidate for a new epic.

Original Request for PDM integration

Which system are you using?
We are currently using Solidworks Vault for PDM. We are also reviewing PLMs (and some ERPs) that can help support revision control. Honestly, I think a future version of Inventree could do what we want but the lack of state control is one the biggest issues we have with the current version.

Examples:

1. if someone changes a part (revision, name, BOM, etc.), it's not easy / possible to stop or track the difference within inventree.
2. revisions - we are constantly making new revisions for build orders. However, we cannot easily look at a Sales Order from the past and know what revision was shipped with out an external database linking revisions to dates.

Would you code the integration or is this something we should do

I could see this going either way, but I do think it may be be best as a plugin. I think the MVP of this effort is some sort of background worker that identifies differences (revision mismatch, missing parts, etc) between the two systems. It would be nice if the PDM could link to the part file in inventree to push any changes - even if it is a manual process. Even something as simple as a plugin that highlights changes in the previous 24 hours (possibly a report?).

Which system is the leading one (ie in a conflict which is the source of truth)

This is always a difficult internal discussion - we end up using PDM as source of truth because it's a controlled source (you can lock out files from being edited and require review to "revise"). However, I think we would lean on Inventree if this could be done in the tool itself as a majority of our team interacts with inventree and only a view have access to PDM (due to cost/training).

What would you like to sync and would this be a static selection or do you require dynamic controls like depending on parameters, responsible groups, weighted rules

I think it would be nice, but not required anytime soon. Personally, I think there is value in users comparing the two databases for mismatch as there's a lot of stuff to review and not just a straight forward comparison. In addition, our PDM only covers mechanical stuff and we have to identify a solution for our other platforms - software and PCBAs.

Do you see PDM integration as part of this effort or a separate one

I think it should be considered as a way shaping future versions on inventree, but I assume it will be best to be seperate them as there are so many flavors of PDM/PLM.
