Inbound Activity not getting created with Campaign Response

Dear Experts,

I am working in a scenario where we are using Campaign Automation for sending Email Survey to business partners.

Mails are reaching the BPs, survey response also coming to the survey tables, But the Inbound activity is not getting created in the system.

I am using standard Transaction type ''0000'' for inbound activity. . which is ''Appointment'' and Category type ''Date'',  direction  ''inbound''

The Action profile for this activity is Campaign_Automation_Activity. . .

I have done questionnaire determination is customizing too.. .

Am I missing a something??

Some linking of this Activity with Campaign element?

Please suggest!!
