Use
The Delete function is permitted for all objects.
You use the function to remove an object from the tree structure.
If you delete an object from the tree structure, you also remove all objects below it in the hierarchy.

You also want to create a database object with the type Export-Import File (PCL2).
The accompanying cluster objects, table objects, and field objects are also deleted.
Integration
If you delete objects from the tree structure of the Interface Toolbox , the
change validation objects derived from these objects will also be deleted.This means that the relationship between the object in the interface format and in change validation is always consistent.

For example, if you delete the field object (LGART) from the table object (RT), this field object will also be deleted from the change validation tree structure.
