Do you need to group your A/R Aged Trial Balance report by Salesperson, Account Set or National Account? Perhaps you have an optional field associated with each A/R transaction that you want to group by.
The A/R Aging By report will generate an accurate A/R Aged Trial Balance and will group the results by the field that you specify.
The Sage Accpac ERP report does allow you to group the A/R Aged Trial Balance report by other fields but it does not take into account that you might change those fields on each transaction.
The A/R Aging By report uses the field values of each transaction giving you the report that you want.
