If a database table exists for an aspect data structure or if data is already contained in an aspect, you can only create additional fields in the existing structure.

You can delete an aspect as an entire unit. Using this function the data, data structure, database table, and environment are deleted.

When you delete an aspect, do not forget dependent objects such as calculated key figures or reports which are no longer useful without the aspect database table. You can, however, keep such objects for the purposes of setting up the aspect again.

You can transport an aspect and all ABAP Dictionary objects, which logically belong to it, into another system.

You can find more details on these operations in Customizing.
