Object dependency syntax in superbom

[#1]

Hi experts,

I have a problem with dependency syntax in superbom, when creating configurable material.

I have one class (variant-300) with 8 characteristics and very big superbom.

When I want to order KMAT, I want to select in characteristic #2 option "B" and in characteristic #8 option "D".

But in superbom I want to have dependency for material (p.0150): 

-select this meterial when I choose characteristic #2 and option "B" 

and

-do NOT select when I choose characteristic #8 and option "D".

Example:

CHAR_2 = 'B' AND

NOT(CHAR_8 = 'D')

But this kind of syntax does not work. Would appreciate some help.

Thanks in advance.

What about something like this?

CHAR_2 = 'B' AND CHAR_8 <> 'D'

It works, thank you.
