Permissions Building

Bigglesuk

Were running Axapta 3.0

Im trying to backward engineer user permissions, basically I want to be able to sa:

"my table is InventTable, now... which users have access to this table"

Im trying to work out permisisons wise, where they are stored. Ive got users and which groups they are in from the tables:
SysUserInfo, UserGroupInfo, UserGroupList, UserInfo.

How can i find out what permissions each group has? i cant seem to find the link, there must be one as you can see it build the permissions it has if you click on a group and then permissions.

any help would be appreciated.

thanks,

Andrew
