RSA Experts, I was wondering if we can run collection (IDC or ADC) for a specific user - just to get update for a User or account. So basically can filters be applied? Also what does full refresh do - how is it different from a normal collection for IGL Data perspective.
No, there is no provision to filter the IDCs or ADCs for a subset of user population. If you do so within the query or filter, then the uncollected users will be marked Deleted/Terminated.
If you have a business requirement that you need to take action between collection then you might want to look at "User Attribute Change Web Service" but this needs a middleware (custom) that can detect a change and invoke the web service call.
