Data integrity errors shows for General Ledger:
"Incorrect procedure. Rollup Account ____ must have at least one member"
A Rollup Account lets you consolidate or "roll up" two or more account balances to give a summary balance. These rolled up amounts are predominantly used for reporting, but may also be used for classification and budgeting.
In GL Accounts / Accounts, the Rollup option is seen on the Detail tab. Once an acount has been selected as a Rollup account, a new tab called Rollup appears. It is on this tab that members of the rollup account must be designated. An account cannot be a rollup account if no member accounts are assigned. Note that it is possible for an account to be a rollup account and have members, and also to be a member of other rollup accounts. It is possible, then, for an account to be duplicated on a report due to the rollup / member status.
