here is my client's requirement.in my customer invoice screen need to add button after analytic account field.if user click on that button then need to pop up a window and gives that parent and child (predefined) analytic fields separately for choose please help me to sort out this issue

thanks

user not like to create parent child hierachy in openerp way.he need to fill them in this type pop up window.

after he select those parent child mapping from pop up, then its should added to analytic account field like normal openerp standard.

(major difference is user's selection procedure.but all of the others are same )
