Prerequisites
A table can only be deleted in the ABAP Dictionary when it is no longer used in any other objects (for example views or programs).
Procedure
With the where-used list , check if the table is still used in programs or other objects of the ABAP Dictionary.
A dialog box appears in which you are asked to confirm the deletion request. This dialog box tells you if the table still contains data.
Result
