> When creating an order with a promotion the tax value is wrong after updating the order if a promotion is involved.
> Order --> Edit Items --> update selected items
> Example:
> *initial:*
> item1 $200
> Promo -$10 (simple promotion -5%)
> Tax 20%: $38.00
> Tax adj: -$2
> --> $ 218.00
> *update:*
> item1 $200
> Promo -$20 (changed promotion to -10%)
> Tax 20%: $38.00
> *{color:#d04437}Tax adj: -$2{color}*
> --> $ 218.00
> Attached a patch to fix it:
> 1) Calc promotion before tax
> 2) enable existing skipEmptyAddresses flag on calcAndAddTax
> 3) use skipEmptyAddresses flag in calcAndAddTax
> Result:
> item1 $200
> Promo -$20 (changed promotion to -10%)
> Tax 20%: $36.00
> {color:#14892c}*Tax adj: -$4*{color}
> --> $ 216.00
> Right know the person working on the order has to manually calulate the order tax and add/subtract it from the initial calculated value. So when updating an order the values have to be checked manually as the promotion is recalculated and may have changed - but the tax is not.
> The proposal is to recalculate the automatic calculated tax values when the order was created. Adding additional tax can still be done by adding a tax value manually.
