I used the PowerCenter Metadata Exchange to query.
There is a view REP_ALL_SOURCES who can provides a list of the latest version of sources defined in each folder of a repository.
But when i used this view, i find that it shows the sources deleted too. I did't find the field who can filter the object deleted. so for REP_ALL_MAPPINGS, REP_LOAD_SESSIONS are the same.
Anyone can please tell me how to show the object only exist?
