Variant Class and Material Linkage table

Hello All,

Please point me to the correct one if so. I am looking for the SAP TABLE where the VARIANT CLASS and MATERIAL linkage is available.

I see table KSSK that has the required linkage details. But this is not holding VARIANT CLASS related informaiton. It has other CLASS Type linkage to materials.

Is there any other table separately for VARIANT CLASS and MATERIAL linkage?

Thanks, Ravi
