Recently, I’d wanted to query one of my custom fields values from project server 2016 database but I couldn’t find MSP_EpmProject_UserView in my content database views!! After a few searches, I found March 2017 SharePoint update that has fixed this bug, but after installation of March 2017 CU, Project server views are still getting dropped out. Finally I found out if you have multiple PWA sites on the same content database, userviews won't be populated!!!! Now how can I query my custom fields values??
