How we can set assembly items because its components are also maintained properly.
Pl. help

Hi,
How to manage items under sub-categories.
Since, there is only categories for Items. But if I want to manage items under sub-categories
Like:
Products > 1)Components 2) Assembly 3) Raw Materials
Non Products > 2) Tools 2) Lubricants 3) Utility

Products and Non-Products are two main categories.
And others are their sub-categories.
