Dear Experts,
I have converted a .unv to .unx universe in IDT. Now I have to modify the universe and remove all the unnecessary tables in data foundation and their objects in business layer.
I have first deleted the objects from the business layer. Checked integrity of business layer : No error found.
Then I deleted some of the tables in the data foundation. and Checked integrity of business layer : Found error in check dependencies. See image beow

I checked local dependencies of the universe, it showed me no error both in dependent resource tab and referenced resource tab.
How can I resolve this error?
Regards,
Bassam Jamil
