Hello Jian,
Thank you - using condition exclusion groups is a good idea. But the "fix value" of condition B depends on the scale values of condition A - and we have thousands of those master data scale values - so I don't think setting up parallel fix values in condition B is so good.
Meanwhile, we have solved the problem by using a combination of scale-value formulas (condition type customizing) in combination with base-value formulaes (pricing procedure customizgin)
Kind regards,
Klemens
