From the GL Journal Entry Screen there is a Reverse button on the bottom.  Clicking on that will generate the question about which batch you want the reversing entry put into.  When you click Process, Sage will create the reversing entry in that batch but you will still need to post that batch.  (or you can edit before posting)
