how I can calculate tax !

35 Views

Hi !

I wonder how I can calculate tax !

Now, I'm investigating if i can make MM-Invoice with batch-input,

and i got 1 question.

In making MM-Invoice, I have to decide total invoice amount with tax before going batch-input.

While I could find total amount ( by deal × per amount), I couldn't find how to get amount of tax.

Is there any function module or tables that have tax-rate?
