SSRS 2008R2 Excel File as DataSource

I prepared a report which binds from Excel file. This file is in my local computer. When I deploy it into the report manager then the users in the company cannot open the report it gives the error below.

An error has occurred during report processing. (rsProcessingAborted)
Cannot create a connection to data source 'DataSource1'. (rsErrorOpeningConnection)
For more information about this error navigate to the report server on the local server machine, or enable remote errors

Where I have to put this excel file to be opened without problem?
