Hi Jim,
You're getting good advice from everyone, but the only thing I wanted to note was what the checkbox allowing documents to be deleted once printed stands for. It doesn't have anything to do with checks. Several releases ago GP created 'documents' that you could print representing PM and RM transactions. It came from customers wanting to get a piece of paper representing a Credit Memo. Instead of just doing that single document, they did them all. So now, if you are in the Transaction Entry window and type in a voucher (invoice, return, whatever), you can select the Print button and it will print a document representing that voucher. Once you print the document, GP presumes it has become part of the business cycle and does not allow you to delete it. Much the same way that you cannot delete a SOP document once it has been printed. Therefore, you would be forced to post the transaction and then void it if it is something you want to get rid of. With that checkbox marked, you are able to delete the unposted transaction even though you have printed it.
Kind regards,
Leslie
