Regarding Role Upload from BW system to Portal

Hi All,

We are using Upload Roles from backend functionality in Portal 7.4 and everything works fine.

My question is when there is a change in Backend role like adding or removing some transaction from the role, will the role gets synced automatically in the portal side or do we need to reimport the role to get it synced?

Is automatic sync option available in any of the previous portal versions?

Thanks,

Satish
