With D365 v9.0 the data structure for business process flows (BPF) has changed. For each BPF exists an own entity.
Together with the Unified User Interface (UUI) and the corresponding app designer the steps for enabling a PBF have changed a bit.

1. Create a new solution
2. Open the standard BPF “Opportunity Sales process”, save it as “My custom Opportunity Sales process” and activate the process.
7. Save, Validate and Publish the app
