I've seen the problem occur, usually Manual Check Entry, where the system thinks the Starting Check Number is 000000. You then change the check number to the correct one (10000) and process, but the system recalls you started with check 000000, and so Voids checks 00000 to 10000. The utility removes all the Void check records within the range you selected. If there are actual voids within that check number range, they will be deleted also. Beth is correct, Reversals are unaffected. But, you do have the ability to purge Void checks withing a selected range for the specific Bank Code, so that should help.
