I have set up the module but I am unable to assign Category as "Data" because this option is not available in the "functional Area" tabl under "category". So I ventured to set up a new category but was unable to do so. Could you please help with how to set up a new category. Anapedia help says I need to get into Administration. This page seems to be unavailable to me.
If this is what you mean then my dear friend, you can not add or delete these categories. These are by default, although there are ideas shared on this in idea exchange forum to let model builders create categories to group functional areas.
