Difference between Report and Update mode
The difference between Report and Update mode is that Report mode lets you review transaction data and Update mode sends transaction data directly to the general ledger. When you run a program in Report mode, you have the opportunity to review transactions for errors or incomplete data and then make corrections.
For example, you can run the Received, Not Invoiced report in Report mode to see orders that you have received but have not been invoiced for. You can then decide whether you want to correspond with the vendor to resolve the incomplete process, or proceed in Update mode and send this information to the general ledger.
