Adjust the customer invoice amount and tax amount

(0) ShareShare
ReportReport
Posted on by

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

    Hi Jianrui,

    The sales tax is working when you set the Quantity paramter to 'All' instead of 'Packing slip'. When you have partial deliveries the Sales tax correction on the sales order is ignored. When the parameter is not set to all, AX can't assume the Sales tax is still valid.

    Hi Andre, i have just verified, the tax amount is still not correct if i choose "All", and the only one packing slip is posted and it post all amount in the order.

    Hi Jianrui,

    Have you hit the button 'Apply' on the Tax adjustment form? If not, the changes are ignored.

    Seems the only way to change the invoice amount and the tax amount is changing the price in the sales order. sales tax also can be changed before you post the invoice.
