Hi all,

i have created two models. One advance and another advance lines. This imports the SO lines From selected sales orders. I have a form that is similar to the SO form so I can add info to the lines. I have created a function that totals certain fields according to the product categories. What I want is a way to display these totals on the form. I am guessing I need another o2m field somewhere but I’m not sure if it should be a separate model or if there is a way to add another one to the advance line model. 

What I hope is I can have two tabs. One displays the advance lines that came from the so and another tab that displays the category totals.
