Hi Ninad,
are there any errormessages in the server log?
Maybe you will have to adjust some ACL Settings to be allowerd to delete DocTypes.
You can try to run the following Build-In-Services with the correct inputs:
wm.tn.doctype:delete
See TNs Build-In-Services-Guide for further information about this service.
Additionally it might be helpful to open a support incident to verify with SAG why deletion of TN DocTypes is not possible via Designer´s Delete option.
Regards,
Holger
