Comment 1 for bug 1205348

Hi,

I just had a look again at the module and now I can describe the bug better:

There is a problem with the plus/minus signs.

Current state:

situation: We've got a refund of Euro 1000 net. Cost price was Euro 800 net.

If I only calculate the refunds (without invoices), I'll get the following results

net amount: -1000
total cost: -800
real margin: +1800

How it should be:

net amount: -1000
total cost: +800
real margin: -200

Would be really great if someone could have a look at this. Unfortunately I cannot fix this on my own. Thank you!

Kind regards

Christoph Uhl
