No able to exceute a ERP InfoSet with a BEx Query in the ERP system

Hi experts,

with the help of ERP transaction code SQBWPROP Maintenance of BW Settings of Classic InfoSets it´s possible to allow acces to a ERP InfoSet with the help of a BEx Query within the ERP System.

I have checked this setting for a example InfoSet and created a BEx Query based on this InfoSet.

But, if I execute the BEx Query with t/code RSRT the "No Authorization" message appears.

Check log per t/code RSUDO:

BEx Authorities in PFCG:

What are the prerequisites to use BEx Query based on a ERP InfoSet in a ERP system?

Many thanks in advance and best regards,

Michael
