The first thing you need to do is to issue another statement. In some cases, the application has errors because bugs in the code. Issue another statement and compare the results. If you still encounter the same error, you will have to check every item and procedure applied to the statement because somewhere something is wrong in terms of money and value. The integrity checker won't show anything as long as the data doesn't have weird characters or large amounts of money. If you have the document opened, close it and then re-open it back.
