Query in DAL Return 0 result for a non admin rigth user

Hello again friend!

We create a DAL Query that work as expect when we run a form from UserApp portal with the uaadmin or a Admin Rigth user, but when we use other normal user the query return 0. 

I was check a lot information in forum and in documentation, buy no get a clue what we need, look like normal user have no privilage to search over the Access sub-trre.

Please any Idea?

Thanks!
