Hi Babalo,
So when you try to use the objects only from the derived table, you do not get data in Webi.
When you copy this SQL (generated from objects only from derived table) and run against database, do you get data? I think no.
The code of the derived table should be checked as it is not giving data. You need to check the conditions and joins used in it and check why it is not giving data.
Share the code of derived table so that we could look into it.
