Hi Ken,
The reason you can't search on the detail amounts is that there is no inquiry into this file (it has no "key").
The fastest way to get the information you're looking for is to use Quik Reports and link to the Posted Transaction File and Chart of Account (if you need the account description). Lay out the report the way you want, with whatever subtotals or page breaks make sense, then add the selection rule
You need the absolute value function to get both debit and credit entries.
