Hi,

I've seen this question has already been asked, but as it is still not resolved, I'm asking it again.

When I display a Quote, Sales Order or an Invoice, the product detail table is not correct. No problem with each line, I can apply tax,& discount on each and the total amount is OK.

But in the summary rows below, Sub_Total is the Total amount of each lin (Tax & Discount included), Tax always displays 0 so that Grand_Total is always equals to Sub_Total. That is very strange. Moreover, I can modify Discount (that is the only one), which is extremely curious (why can't I modify Sub_Total, Tax & Grand_Total ?).

What I expect is that :

 - Sub_Total is the sum of total amount of each line excluding Tax & Discount

 - Tax is the sum of taxes of each line

 - Discount is the sum of discounts of each line

 - Sub_Total is the sum of total amount of each line including Tax & Discount

As some people may have a different computation, a better way is that these values can be updateable (keeping actual default values if needed).

This bug (because for us, it's a bug, and it's unacceptable) is a blocking point for us.

Many thanks in advance for your help.

Regards.
