Group Accounts - LATCO using Agresso

We’re currently setting up a LATCO which will be 100% owned by the Council. We expect to producing group accounts for the Council with a full consolidation of the LATCO. We use Agresso for the Council’s system and will be setting the LATCO up within Agresso too.
Was wondering if anyone had experience of using Agresso for similar purposes and had any hints and tips on things to do / not to do?
Did you use the system to consolidate accounts or seperately using spreadsheets?
