Multi-level Categorization is a kind of hierarchical categories which can be used in the business transaction to classification purposes. For example, in the service order, we can categorize the defect, reason, solutions into many hierarchical categories. One or more than one can be selected easily from the hierarchical tree in the service order header or item.
We can take the multi-level categorization as an enhancement to the previous subject. In a subject profile, we can define Catalog, under the catalog we can define code group, and in the code group we can define code. That's all. The multi-level categorization is more powerful which can have as many levels as you want. The categorization is linked to the catalog/code group/code.
Multilevel categorization is available in varying scopes for the following applications:
