Hello,
So far the closest solution is in fact a mixture of the 2 previous posts:
- Condition rule is now G (with B I have the problem described in my first post, currency cannot be entered in VK11);
- Condition base value is now determined by formula 1 (Volume);
However this solution is far from being perfect - in fact, I cannot maintain KPEIN and KMEIN in VK11. That means that I can create a tax of 2 EUR but not 2 EUR / 1 Gallon. With this problem, the formula cannot determine the correct conversion because KPEIN and KMEIN simply do not exist in the condition record.
I'm starting to consider the following workaround: maintain KPEIN and KMEIN in the condition record text - not that I like it, of course, but so far it seems like the only way.
Regards,
João
