Authorization for browse data from infoprovider in Bex Analyzer

Dear Experts,

Currently there is some users that can select infoproviders in Bex analyzer (infoprovider tab when you open a new query) and then execute it (not a query, just the infoprovider), but some others users can´t do this.

Can anybody help me in order to know which authorization object can be use to restrict this ?

Thanks in advance!!!
