Material Group

Dear All,

My client want to bifurcate material groups in sub groups.

Is there any option for such kind pf requirement?

Can I use other fields from material master basic data 1 like External material group,basic data in baisc data 2 screen.

I have already used product hierarchy for some other purpose.

Client dont want sub grouping in product hierarchy.

Thanks in advance.

Regards

Gitesh
