Hallo,

here is what i want to do:

in sale order there is a field which contains a discount percent value.
if i add a new line to the order the default value of the discount field of sale.order.line should be the value of the discount percent field of the sale order.
I know i have to inherit the sale.order.line class and add _defaults {discount: but i don't know how get the value of the field in sale.order, becaus sale.order.line.order_id isn't filled out yet.

any ideas?

Thank you.

aw

Defaults could work but it would be really messy and user unfriendly IMO. Having to save parent, then sale order line to populate default.

You should use an onchange method instead which can access unsaved values. A lot like a sale order line uses the unsaved parent pricelist when calculating price.

You are absolutely right.

I shouldn't do such things on friday afternoons...

I'll try it that way.

Thank you so far.

works fine.

Thank you.
