Invoice rejection interface

[neoandr]

Hi,
I need to reject an invoice interface if the invoice amount mismatches with the original shipment amount. This rejection should be acknowledged with an interface to the client with the invoice details.

I have list of OTM interface but wanted to know if this possible in OTM
I know that it can be done through Agent email notification. But is it possible thru interface

Appreciate your help.

Thanks!
