I would like to inform you that we cannot proceed processing the Tetra Pak invoices because upon checking, PO 8000176827 was created with a single service item. We cannot post an invoice with this set-up. There is a need for alteration shopping cart to create a separate line item 20 and this sub service line will be transferred to it. However, if there are multiple invoices intended to this PO, it would be better to indicate on the internal note of the alteration shopping cart that line item to be created is a limit type to avoid future blocked items.
