For the information to be sent correctly, the "service code" informed in the supplier's invoice must be the same as that related to the item, however this information we only have when the supplier issues the invoice and this is after the entire purchasing process, opening of Purchase Requisitions, approval flow and formalization of purchases.

The service code could not be linked to the item.

Our suggestion to solve this problem would be to exclude the Service Code column from the items part and include it as a mandatory field within the Contract and Purchase Order, being able to change it according to the invoice.

Ideally, it would be possible to include a field for a service code in the supplier contract (Purchasing > Purchase contracts > Purchase contracts).
