Dynamic attributes are created through the attribute group they are associated with. The first step in creating dynamic attributes is locating the attribute group.
If the dynamic attribute you are adding will be associated with an existing attribute group, follow the steps in section Locating an Existing Attribute Group.
If a new attribute group is needed for the new dynamic attribute, follow the steps in section Creating an Attribute Group.
Once you have located your attribute group, continue on to section Adding a Dynamic Atttribute to An Attribute Group.
