SSRS Reports - AX 2012 - Issue asking for credentials

If you found yourself in the situation where every time you want to run a report in AX 2012 and you get a prompt in the report design for credentials (user and password) then this means that you have a problem with the reports' datasource; meaning it has forgotten it's settings that should be A custom data source with Microsoft Dynamics AX report provider / Windows integrated security and instead it has now  A shared data source / Credentials supplied by the user running the report.


So, just reselect the required settings mentioned above or if the problem presents itself in all the reports just deleted the entire content of the DynamicsAX folder and redeploy the reports.
