It’s very common for orchestrations to access databases or executing stored procedures. Whether this access is done by SQL Adapter, WCF-SQL adapter or through C # code if we are not careful to set the user permissions properly in the database, we can get one of these errors:
Cannot open database ‘…’ requested by the login. The login failed
or:
The EXECUTE permission was denied on the object ‘…’, database ‘…’, schema ‘dbo’
CAUSE
This problem occurs because the user account that you used to access database or that tries to execute stored procedure does not have sufficient permissions.
SOLUTION
You need to grant permission to the user to access database and/or to execute stored procedure.
Normally orchestrations are running under BizTalk Application Users group but you have to check the windows group configured on the host instance that runs the orchestrations which want to access the database.
