It has been mentioned on the Office365 roadmap, that Microsoft was planning on the release of a default “number generator” for Project Online customers. This functionality has been a standard request for almost all Project Online/Server customers as it ensures you can easily connect to e.g. the numbers used in the ERP system or elsewhere. The new feature is now enabled and ready for Project Online customers to use.
The approach to use it is simple.
Navigate to your PWA Server Settings and go to the Enterprise Project Types
Notice the area “Project Id”
This is where you configure how the number string should be generated. It can obviously be set differently for each of your EPTs “Enterprise Project Types”.
Add the new field to your Project Detail Page

Reporting on the ID using (…PWA path/_api/ProjectData/Projects)
Use the new Custom Field “ProjectIdentifier” found in the Projects OData feed:
