I need to add a qualifier for my setup in the qualifer

create a price list

go to qualifier

add customer group

the group channel is not there I need to add the group channel

How can I do that I mean I need to add in the list of value of the qualifier context and attribute another value like channel group

I went to add from the advance pricing responsibility

context and attributes and not able to do that

How can I do it?

do you have a white paper?
