In GP2015 or later, a feature was added to warn a user if a PO exists for a vendor that a payables transaction has been entered for. If you click the Go To button, the transaction you were working on gets deleted and the PO Navigation window is opened to view PO's for this vendor. The message does not appear until the save button or the post button is activated. If the transaction had multiple distributions added this information will be lost and the user would have to start over again if there was no PO and the transaction should be entered in the Payables Transaction Entry window. I suggest that the Go To button minimize the window and then bring up the PO Navigation window for the vendor instead of deleting the transaction.
