e-manage|ONE acknowledgements are to confirm vendor orders. Create multiple acknowledgements for a PO if there are multiple ship dates. This helps you better track what actually shipped so you can receive the items in the receiving module, deliver/install what was received, apply the vendor invoice to the acknowledgement for the shipped items and invoice.
All vendor invoices associated are applied to the acknowledgement. By doing this e-manage|ONE automatically tracks PO’s that have not been fully acknowledged by your vendor and Vendor invoices you have not received from your vendor. These features help to ensure that you are not missing anything from your order and that you have not been invoiced for the items yet.
