After an upgrade, the Project Manager field in the Project Create view no longer auto-suggests values while typing. However, it still does in the Edit view.
After reviewing the Project Manager related lookup, all auto-suggest settings seems correct. All add-ins (clarityContent, csk) are fully installed.
Release : 15.9
Component : CA PPM SAAS STUDIO
Remove and re-add the attribute from the create view.
After re-adding, flush Clarity caches, and if this still does not make the auto-suggest work, add the attribute in a different column and set it back to the original position.
