In 14.2 prior to upgrading to 14.3
Create a custom object; this in turn creates a custom lookup.
After upgrading to 14.3 log into PPM.
From Admin tool go to lookups .
Navigate to custom lookup that needs to be modified.
Expected Result: You can modify the lookup
Actual Result: There is no way to modify the lookup as it is noted to be system restricted.
The system should not change the lookup to restricted.
Currently Still In Progress.
From CA PPM 14.3 to CA PPM 15.1.
Create a new Custom lookup.
