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.
Create a new Custom lookup.
