Hi,
I think we need more detail info
You only have one Tax or multiple Tax, depending on type of sale or market?
You want to calculate in all quote lines or only on total amount?
You can use different approaches: Business rules; calculated fields; PA (in more complex scenarios)
In my organization we have a complex scenario with different taxes accordance with the market, exemptions...and we have the calculation in every line of order (We assumed that in OPTY and Quote we don´t need this information)
We have a PA
1.Trigger: create/update - salesorder lines
2.Will see the type of sale and market on the salesorder (two custom fields - option sets)
3.update the field Tax with the crrect value of VAT
4.update a field tax value (€)
5. update total amount of the line
In this way you will have in the body of the salesorder the correct ammount:
Salesorder value Before tax
and
Salesorder totalamount
See if its help
