In my department, projects have one to many deliverables. Each deliverable has one to many SharePoint files and each file can relate to multiple deliverables - in a classic many to many relationship. Files are stored in a SharePoint document library. As far as I know, I can't create this join table in SharePoint. Is it possible to create this using PowerApps so that there is a place to match deliverables with SharePoint files in a many to many table? If no, is there another Microsoft online tool that can be used to accomplish this?
