Audit Trail for User-Role assignment history
in Portal (EP6 & EP7) - is there any functionality by which we can get history of role assignment been done? I mean - I need an audit trail for which role is assigned or deassigned from a particular user at which time. And from role side which users are assigned and deassigned to it. We are having problem in tracing the role assignment as we are unaware of this kind of functionality. We have both EP6 and EP7 in our landscape - so need solution for both of them if possible. If there is no in-built functionality - any idea how we can write a custom component here to achieve the same? In that case it would be really helpful to get some guidance on which table to access to create a report on this requirement.
Thanks to all for your time.
