Message text: &1 &2 Account &3 requires an assigned group account
This situation occurs when the <LS>Group Account Number</> indicator is
set for the financial reporting structure and the related validation
discovers that something is incomplete.
If this indicator is set, a group account must be assigned to each
account. The system checks all accounts that are assigned to a financial
statement item of the financial reporting structure.
The <LS>Group Account</> field of the Account entity can be entered only
if a group chart of accounts is assigned to the chart of accounts;
otherwise, this field is not ready for input.
The changes can be saved.
Either assign a group account to each account listed, or do not set the
<LS>Group Account Number</> indicator.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
