User access to PBCS from Ad hoc Grid in EPRCS

Content

Hi all, 

Our customer has the old subscription license, PBCS and EPRCS, but not the same amount of users in both. So the questions is,  maybe silly question, but ..Can an EPRCS's user access to a PBCS cube set in the Data Source eprcs connectios?  or it has to have an PBCS license subscription?

Hope you guys understand the question.

Thanks
