Hi there,
I have a sales order which has packing slip posted, For some reasons, we have to adjust the customer invoice mount and tax amount.
On the sales order form, i clicked the "Sales Tax" in "Tax" group of the "Sell" tab, then i adjust the amount and the tax amount over there.
Then i tried to create the invoice on the "invoice" tab of the sales order, on the invoice form as below:

i click the "Sales tax" button, but on the pop-up windows, i found the tax was not changed, even though i can change the amount and tax again on the invoice form, i'm still confused why the system allow me to change the sales tax on the "Sell" tab, does it only take effect before i post the packing slip or what ?
many thanks
