The PO is consigned,but the system allows to bill in Oracle.

Dear Team,

I can reproduce it only test instance but it is issue on Prod. I use NO_AP_SUPERVISOR responsibility. Enty=> Invoices submenu.

I write he PO number to the PO Number field and I fill the Invoice Date, Invoice Num and Invoice Amount after go to the Match option, find the PO. This form I ticked the Match field and I click the Match button. I got the following Note: "APP-SQLAP-10074: This purchase order line is closed. You may want to review the purchase order before continuing with this match." 

I clicked the OK. Follwing sreen I go to the Calculate Tax option, I change the Invoice Amount on header and Actions...1 button , Validate, OK.
