In order to find all the Items where Embed view is used, create a View with the user defined criteria
(obj_description like ‘%FILTER_%’)
Use the same View for all Items
In addition, if you want to filter the Items in which the Embed View/Filter does not have the current Project version than add the Condition (obj_version <> [QMV]) to the above criteria
So, the Complete user-defined criteria for such case:
(obj_description like ‘%FILTER_%’) and (obj_version <> [QMV])
