Yeah, working for the government means almost all sites are blocked.
Anyway here are the results in the Details section:
First I got:
First Group Read Only
Read Only
Read Only
Second Group Read Only
Read Only
Read Only
First User Full Access
Full Access
Second User Full Access
Full Access
Full Access
And that result was because the report was showing the same access for each version of the document. So I put Suppress If Duplicated on the rights formula and got:
First Group Read Only
Second Group
First User Full Access
Second User
So I put "previous ({PEOPLE_1.FULL_NAME}) = {PEOPLE_1.FULL_NAME}" on the Suppress If Duplicated and got:
First Group Read Only
Second Group
First User Fulll Access
Second User Full Access
So then I put "previous ({PEOPLE_1.FULL_NAME}) = {PEOPLE_1.FULL_NAME} and
previous ({GROUPS.GROUP_NAME}) = {GROUPS.GROUP_NAME}" thniking I would now get the Second Group access but did not.
