Maintenace Table to be deactivated delete button

Hello Frds,

For client requirement we have created one maintenance table and converted to Tcode,in this tcode we need to deactivated the delete button.

Deactivation of deletion button can be control through authorization object with Basis? or Abaper can do the same?

If basis has to create authorization object how can we create with our customize table authorization object.Anyone can suggest how can we proceed for the same.

I appriciate your valuable inputs.

Regards,

Nivas.
