Bit of a fun one today, Essentially I'm having to rebuild a custom version of the inbound shipment transaction, so my questions would be, is there anyway in for us to create elements similar to it's "Add PO Items" selector, this seems to be some new ui functionality. If not, i'm going to need to build something similar, which I'm assuming is going to be suitelet only territory, what options do I have with dynamically sourcing data based on selections in other fields?
