BDC Access Denied problem

Hi,

I configured External Content Types in SharePoint Designer 2013 and then created a list using it. My SQL database is on a separate server. When I try to open the list in SharePoint 2013 it gives me an error:

Access denied by Business Data Connectivity.

Correlation ID:b715139c-8e60-90c3-8e65-956bdb1db2c4

I am using domain Administrator user name when I login to SharePoint. I added it to BDC Service Applications permissions (Set Metadata Store Permissions) and gave it full rights. I also gave Administrator user name read/write permissions on SQL database.

I still get "Access Denied by BDC" error.

I can't figure out what the problem is.

Help would be much appreciated.

Thank you.
