If this is a new group on the Receipt Entry Detail window, you can use the drop-down list in the Group Num column to enter receipts into a group or batch that has not been posted yet (Status of U nposted or S uspended). Also, It is helpful to remember the Group Number for the receipts that you generate so that they will be easy to find when you are ready to post them from the Transactions Group window.
