“There are no plans to release this in a CU for Project Server 2013 or Project Server 2016. For now, it will remain an online feature.”
“Neither. It was a limitation imposed by us supporting multiple PWA sites in a single database. We have since increased the limits by adding additional tables to SQL to support the additional custom fields.”
“Yes! As a PWA admin you can add the Project ID field to a project details page and make the field editable. You can also update the field programmatically using CSOM.”
“Awesome! Great to hear Project IDs will help!”
“Great to hear you are excited about these three new improvements!
Q1: The Project team is just wrapping up the Project Server 2016 release and unfortunately Project ID functionality will not be shipping with Project Server 2016.
Q2: Having complex formulas on lots of custom fields can impact performance. I would recommend for formula custom fields that are not required to be in line with the schedule edit experiences to rely on reporting tools to calculate the required values.”
