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cannot be created because the credentials used to run the report are not stored, or if a linked report, the link is no longer valid.

Very often when you are trying to subscribe for a SSRS Report, you may end up with the error saying "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cannot be created because the credentials used to run the report are not stored, or if a linked report, the link is no longer valid.". Sample screenshot as shown below.

There might be quite few reasons for this. One of the reason I found out is that, the report you are trying to suibscribe is using a Shared Data Source.

To have this resolved, below are step by step Instructions.

1. Click on the arrow Mark on the Right most corner or report menu as below and click Manage.

2. Now click on Data Source as shown below and select the Radio Button "A Custom Data Source". Under Custom Data Source, select the Type and enter the Data Source and Click Apply.

3. Now go ahead and subscribe for the report. You will be able to successfully create a Subscription for the report.
