SAP Leave Request Team Calendar error

We upgraded to EHP7 from EHP5.

When we launch leave request screen in approval mode in POWL and try to view Team Calendar, we are getting error message "No team setup for user, Please contact administratior". This is working perfectly fine for same user in EHP5. We found a related old note 1501310 which talks about same issue but not applicable to us.

But if user clicks Select Team Member's button and select all employees, he is able to view team calendar. By default, we would like to display all team members when the user clicks Team Calendar tab.

Thanks,

Baba
