Unable to add Outbound Interface to Businenss System in PI 7.1 Int.Dir

Hello,

Usually when you display the Business System in Integration Directory, there you have the buttons to insert Inboud or Outboud Interfaces using Receiver or Sender tabs.

These buttons are not present, when I display the Business System. I am using PI 7.1.

Is there any thing I have to perform or do something.

Thanks in advence for you help.

Thanks,

Namadev
