For guidance with adding SAS users, see [SAS Documentation](http://support.sas.com/documentation/cdl/en/mcsecug/69854/HTML/default/viewer.htm#n05epzfefjyh3dn1xdw2lkaxwyrz.htm).
In order to surface a table to a new group, simply add a record to the `DATACTRL.MPE_SECURITY` table. The `library.dataset` value should go in the `BASE_TABLE` field, the level of access (either _EDIT_ or _APPROVE_) should go in the `ACCESS_LEVEL` field, and the exact name of the relevant metadata group should go in the `SAS_GROUP` field. The change should then be submitted, and approved, at which point the new security setting will be applied.
