Create characteristic values combination without having a value for every characteristic

Dear all,

When I use tcode /SAPAPO/MC62 I can create characteristic values combination. We have 6 characteristics and for some combinations we want to fill let's say only 5 characteristics with a special value. One characteristic should not be filled. It should stay default and could have any value which is possible for this cahracteristic.

Is it possible to leave one characteristic blanc in this transaction? Or must I assign a value to all characteristics?

Thank you very much and kindest regards,

Eva
