When I split a sales order that has a promotion (30% discount) the original order does not recalc the discount but the split off items do. Anyone know how to trigger a promotions recalc on or before record save?

what does the code look like

The code just copies the order (standard mode) and removes or closes items. What I'm looking for is a way to trigger recalculation of the promotions. For some reason the original order promotion keeps its value even though some item lines were closed.

sounds normal to me

Lines are also adjusted to $0, which changes the order total but the promotion does not update/change the % value.

need more code

The code is over 1k lines

you do not need 1000 lines to close a sales order line and set its amount

All I'm looking for is a way to force a recalc on the promotion. Doesn't seem possible in standard mode

its automatic

and yet it doesn't work.....

which is why you want to identify which code is not making it work
