Rate characteristic using ECM

Hi there,

we've got a special requirement for classification using ECM I have to approve and I need some help.

A class ZCL01 has several assigned characteristics, e.g. ZCHR01001, ZCHR01002 and ZCHR01003. Now it is required that for one characteristic, like ZCHR01002, that every rating must be changed using ECM and, at the same time, all other characteristics (ZCHR01001 and ZCHR01003) can still be rated without using ECM. Only ZCHR01002 shall demand ECM for new ratings.

How can I adjust the settings properly for a scenario like this?

Thanks in advance for your help.

Regards,

Ben
