These are the steps I did under the local administrator:
I go to central admin -> application management -> manage service applications
I click on New-> Business Data Connectivity Service
I enter/select the required fields like name, application pool, application pool identity and click on OK. After a while I see some text that my BDC is created succesfully.
No I see the list with all service applications. When I click on my created BDC service application I got this error:
Error An error occurred. Administrators, see the server log for more information.

In the event viewer I see this error:
The BDC Service application BDC is not accessible. The full exception text is: Access is denied.
Why I get this error? The user which I am logged in is the local administrator and is the site collection owner. BUT I have selected another user account for the application pool for this BDC.
