When I use the Accept/Propose Change action on a PO Line sometimes the Accept button is greyed out and I cannot accept the order. I can only click Propose Changes or Hold what is going on?
It's possible that the order line is Late. The Accept/Confirm Action is only available on PO Lines where the Buyer has made or proposed a change. Accept is not available when an order line is Late. Remember order lines that are Late and have triggered the buyer's tabbed based notification (reminder emails) will also be in the Supplier's Updates tab. Late orders need to be updated with a new proposed date so Propose Change is an available action. Suppliers can also create an ASN with SourceDay by using the Shipped action.
