This is how you create maintenance dialog for ztable.

Use tcode SE11, enter the table name click change. In the next screen, click Utitlies-->table maintenance generator.

Enter &NC& as the auth group.
Enter the function group to use (ex. Z_TABMAINT)

click One Step, enter '1' as the screen number. Click the create button.

Once generated, you can use it by going to SM30, enter table name and click maintain.
