After you have entered all transactions in a batch, you should print the batch listing and compare it to your source documents to be sure all transactions were entered correctly.
If you find mistakes, edit the batch to correct them, then reprint the batch listing and check it before you post the batch.
Tip: To make sure listings are printed for each batch before you post it, select the Force Listing Of All Batches option on the A/R Options screen. The option also prevents you from posting batches you edited but did not relist.
