A tree view of item groups consist of twenty horizontal levels. All the horizontal levels are independent and are not related to each other. Each horizontal level consist of five vertical groups. These vertical groups are further allocated with subgroups according to the requirements of the user. According to the type of the groups the items are allocated to them. The item allocated to one subgroup can't be allocated to the other subgroup with in the same level.

GST is allocated in Setup Item Groups to automatically allocate items to the groups.
