Inventory Structure

I am trying to make a simple inventory app.

I would like to make a list where you see just one “Job” and when you click on the Job you see all the Po’s associated with that Job and all the parts associated with that PO… Any suggestions?

Use the Inline list and add the filter.

Wouldn’t you want to show multiple jobs, and then when you click on one job, you see POs and Jobs associated with that job?

It should be company not jobs. So it should go
PO’s & Parts
Companies can have multiple PO’s and that PO can have dozens of parts. That make more sense? Thanks for looking and helping.
