Multi-level Categorization is a kind of hierarchical categories which can be used in the business transaction for 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.
Multilevel categorization is available in varying scopes for the following applications:
- Service orders
- Service order templates
- In-house repair orders
- Case management
- Interaction record
In some cases if we need to know which level in the category is filled , then we need to calculate the node level which is filled and based on that we can determine whether the node level which we have to look for is filled or not. For e.g. in defect there are L1->L2->L3->L4->L5 , then if we need to find out if L5 is filled or not and if only level L3 is filled then the output that we would get is level 3 and we sure that L5 is not filled. In some business scenario we need to determine if a particular level is filled ( Level has to be filled mandatorily in the transaction). If the level is not filled we need to raise an error message. So the blog below would help to calcuate the level in a category. Using the APIs in the code below , you can twist and tweak as per your requirement.

The lv_sel_level would give you the level details. Based on business sceanrio , we can add validations .
