Assignment of number scheme to category hierarchy

Hi,

I maintained the number scheme in the path Cross APP component->SAP Product->Product Category->Define Category Numbering Schemes.

Now as said in the related document in this IMG

*After creating a numbering scheme, you can assign it to a category hierarchy, where you can define whether the IDs are assigned automatically or manually.*

I want to assign the created number scheme to category hierarchy but not getting the path in IMG.

Please let me know where it can be done.

Regards,

Rahul
