Generating BW DSO is removing Analytic Privilege from HANA

Hi,

We are using BW on HANA. In BW Devlopment system, we go to tcode RSA1, select the DSO (Info Provider) and have selected the check box

for "External HANA View for Reporting" for our DSOs. Activating this DSO for first time, is creating an analytical privilege and HANA role in HANA dev system. This is working properly.

So now the DSO is already activated in BW and in HANA we have the corresponding Analytical Privilege. The problem is, later if we activate this DSO in BW, the analytical privilege disappears from HANA. We have to activate the DSO once again and then only the privilege is re-appearing in HANA.

Shouldn't the analytic privilege be available in HANA after each activation of Info Provider (DSO) in BW? Do you know why the analytical privilege is appearing only after activating DSO twice? Is this how it works or is there something wrong in BW system?

Its working in same way in sandbox system also.

Thanks
