Could you please be more specific if you are looking for report of Assigned Roles,Groups,Users etc i have come across this , but if you are looking for View Report (Provision Report) then i need to do some work to come out for it if you manage to come across with a solution on this post happy to see implementing in our project as well.!!!
I dont see any utility or way to reach out to report automation, as a workaround i can provide you with below query which can give the provision information which would be simlar to Provision Report.
Run the below query on Shared Services Schema.
select p.application_id,p.createdtimestamp,c1.name,o.name,o.locale from
css_provisioning_info p,css_groups c1,css_role_locales o
where p.member_identity in c1.identity_id and p.role_identity in o.identity_id and
o.locale='en_US' and p.application_id like '%XXXXXX%'
order by c1.name
and You can automate this to get a report pulled at our desired timings.
