I have created a new database on MS SQL SERVER SHAREPOINT instace that contains two simple tables.
Then I tried to link values defined in these tables by implementing External Content Types using Sharepoint Designer.
The process seems to worked without any errors but now, when I try to access the External List based on this contents I receive the error:
Cannot connect to the LobSystem (External System)
I check all permissions on new database, Business Data Connectivity Service, etc. but I didn't found a solution to this.
Do you have any suggestions what could I be missing?
