Dear all,

sorry about noob question. 

My 2 cents knowledge point me out that I can find action for button. but I cannot find in sales order.

here is my problem:

1. when I create SO, i need to add "Add a product" button to see the "Create Order Lines" pop up form.

2.  the pop up form is appeared and I would like to know how to find the "Save & Close" action in this pop up form. can experts guide me where and how to find it?

I used odoo v12 enterprise version.

BR,

Joozer
