I created 2 SSRS reports - the first report had the embedded Datasource and Dataset exclusive for this report and the second report had a shared dataset and datasource. After deploying to SharePoint 2013, the first report ran fine but when i'm trying to execute the second report, i saw the following error.
The current action cannot be completed. The user data source credentials do not meet the requirements to run this report or shared dataset. Either the user data source credentials are not stored in the report server database, or the user data source is configured not to require credentials but the unattended execution account is not specified. ---> Microsoft.ReportingServices.Diagnostics.Utilities. InvalidDataSourceCredentialSettingException: The current action cannot be completed. The user data source credentials do not meet the requirements to run this report or shared dataset. Either the user data source credentials are not stored in the report server database, or the user data source is configured not to require credentials but the unattended execution account is not specified.
Any thoughts?
