You must configure the unattended report Processing Account

I am trying to automate my report procces and I am getting this error on one of my reports and not sure where or how to config this  

I get this under perview

An error Occurred during local report processing
an error has occurred during report processing
cannot creat a connection to data source "trulinx'
you have specified integrated security or credentials in the connection string forthe data source is configured to use a differeent credential type. to use values in the the connection string , you must config the unattenede report processing account for the report server.

You need to change the datasource proporties into "Credentials stored securely in the report server" and give it  User name and  Password.

That user & password should ONLY be a domain member with read only access to the databases you wish to query as well

Where is the datasource setup? is it a shared datasource thats located on the SSRS server or is it stored local on the RDL File?

if its on the RDL file you need to open in BIDS or Visual studio.  If its shared on the server, navigate to the reports server in IE and find the datasource, it would be under the Properties page of the datasource.

My vote's for a shared datasource, reason being is if for some reason i ever had to change that password, i only have one place to change it rather than N+1 reports that need to be modified

Gotti, yes you can easily change it to a shared DS< you just need to create one on the report server, then on the reports Properties page you can change the datasource.

In BIDS, if you click on the DATA tab, then the elipsis beside the datasource you can change the connection.  If you can't find it let me know and i'll take a screencap

First when you create your datasets for your rdl file use shared datasource and you data connections choose to specific  user name and password.
Once you deploy your report to report manager, make sure that it is not asking for user name and password. If it is asking for authonitcation go to proporties of the report and select datasource and point it to the datasource  in your datasource folder.
For the email it could be cerdential issue too.
Let us know if this is not solving your issue.

I tried all my users and passwords and nothing seems to work.   I tried going to data tab  edit dataset , datasoruce and used shared data soruce refrence is checked and credentials is all grayed out .. I can log on to the tables just fine now... there are like 3 set of credentials i should be using .. one for datasource  one for  depoly and one for subcriptions dont make sence
