Activated variable 0cmonth from business content

Hello,

I have activated variable 0cmonth from business content but I do not see it as a characteristic value variable option in BEx query builder under 0calmonth2.

Do I need to reactivate the infocube that contains ocalmonth2, reactivate the infoobject 0calmonth2, or is there another way to link variable 0cmonth to 0calmonth2?

(BW 3.1 release 3)

Thanks,

Mark
