Can't select any item in vocabulary HRF 1.0 SP07

Dear Experts,

I installed SAP HANA Rules Framework 1.0 SP07 on HANA SP11 1.00.111.00.1454183496 (fa/newdb100_rel) used for GRC 10.1. I'm using Eclipse Mars Version: Mars.2 Release (4.5.2) Build id: 20160218-0600 with SAP HANA Tools 2.2.8 and necessary HRF 1.7.1.

I've created a project for HRF and added a vocabulary :

I'm connected as user SAPGRC which has theses roles, developper is also included.

and object privileges :

and package privileges :

But I can't select any item or column in any table I bring in Data Foundation.

I don't see what rights or privileges should I add to work, I've tried with several other users, even SYSTEM after adding the same right and privileges on schemas, packages, roles but I must be missing something.

Could you please help me on getting arround this issue?

Thank you in advance!

Christian
