SSRS Subscriptions cannot be created

Applies to:
  • Microsoft Business Intelligence Development Studio 2008 (BIDS)
  • Microsoft SQL Server 2008 R2
What?
This article describes solutions to the error:
Subscriptions cannot be created because the credentials used to run the report are not stored, or if a linked report, the link is no longer valid.


How?
I'd like to say that the solution is far more complicated then this, but it isn't. This is one of those rare situations when the Microsoft error is describing the exact problem.

If you include linked images in the report (as in images not in the report itself but referring to other systems holding the images), then please refer to my article on SSRS External Images don't display.

The answer to this error is your report needs to use a datasource with the credentials stored, here are the details to our report
  • As developers, we connect to the datasource directly using our Windows Credentials.
  • For the SSRS server holding our report, we do NOT have an unattended service account.
  • The report uses a shared data source which stores the credentials, ie. A sql authenticated user with read-only privileges.
  • The report has 4 parameters, two of them use the default values (from and to date range) and two use specified values (setup in the subscription section).
  • The report being subscribed to is hidden in tile view.

Cases where this would NOT work
  • Reports where the connection string to the data source is held in the parameters (though, with more time, we could have tried changing the "connection string" parameter to "shared datasource" parameter where the user can select which "shared data source" to use).
  • You might be able to get this working with a shared data source but in our case the shared data source didn't have the correct database (initial catalog) specified despite looking at the correct server. We created a separate data source for this report.
