Sage 100

I would like to customize the Summary Package Tracking panel but the right-click customization option is not available. I am trying to ensure the user enters tracking information into this panel before Accepting the shipment. Any suggestions are appreciated…

Is there a way to customize Item memo so if certain customers order that item a pop up will show up on the sales order. Possible by customer number or country code. We have some items that can not be sold in certain countries.

Would someone be able to tell how I would go about setting up a way to track lost sales? We are using Sage 100 Advanced ERP, Version 5.00.1.0...
