Question about Sub Accounts

Hi All, We currently only have the Detail Accounts setup without any Sub Accounts. e.g our accounts are setup as 01700 01701 etc We would now like to add some sub accounts so for e.g 01700 - 001 01700 - 002 As far as i can ascertain these seem to be created as New Detail accounts and also seem to be coming up as separate entries in the GL291 (instead of 1 entry for the main 01700 account)? Is there a report which i can run to see the combined posting of the account (i.e 01700,01700-001,01700-002....) as i can in the GL95 screen? Thanks Saurabh
