The project primary contact is the individual who owns project completion and is indicated as such in the project metadata. Users must be designated as a primary contact candidate before they can be assigned that role at the project level.
You must be a Super Admin or have access to the Organization Settings in order to set the project primary content.
Go to Organization Settings > Users > Manage Users and then click the user name.
Under Attributes select Project Primary Contact.
Click Save. Each user assigned as a Project Primary Contact will now be accessible on the project metadata.
The project primary contact attribute for a Super Admin is locked (grayed out/disabled) in the individual profile view because it is set at the point of role assignment. However, a Super Admin can update their own project primary contact attribute by using the Bulk Update feature:
Note: This action must be performed by the Super Admin user themselves — it cannot be done on their behalf by another Admin.
Go to Organization Settings > Users > Manage Users.
Check the box next to your own user account.
Click Bulk Update Users from the top navigation header.
Update the Project Primary Contact attribute and click Update.
