Order entry app - guidance around checkout and availability check

Content

Hi All,

I am designing a small order entry application in VBCS which allow the users to search for the items and create orders.

I have created a landing page will allow the users to search for the items either by item number, description or long description. All the items which match this criterial will be shown in the results table.

My requirement is to 

1. show the available quantity and the tentative deliver dates for that item ( which can be in a different table / system ) with in the results table.

2. allow the user the add all the selected items to the cart and provide them an option to check out once the user is done with selecting items.
