You have set up a custom attribute - Dynamic lookup showing instances of an object. You are seeing some of the below behaviors:
How to configure the lookup so it filters the values? You need both Active and Inactive values to show saved in UI on the attribute, but once the users filter, they would like to see only Active Lookup values
All Supported Clarity Releases
The lookup code does not contain a BROWSE-ONLY clause or the construct is not correct
You have to use BROWSE-ONLY in the query for your dynamic lookup to allow for this functionality. This is valid for both Browse and Pull Down lookups
BROWSE-ONLY will make the condition apply only when selecting (browsing) new values, but not when displaying current existing values.
An example of using the BROWSE-ONLY construct:
SELECT ...
FROM ...
WHERE @FILTER@
@BROWSE-ONLY:
AND IS_ACTIVE = 1
:BROWSE-ONLY@
Note: You have to make sure you update the lookup when not in use or use XOG to apply the changes to the lookups
