Trying to process the cube but getting the error at impersonation information

Question

I have built a cube in Business Development Intelligent Studio(BIDS) using some database with the name 'Test_cube' which consists of Products dimension table, customers dimension table and orders fact table.
The products table attributes :prodID-primary key,prodname,prodtype,prodcost
The customers table attributes :custID-primary key,custname,custloc
The orders table attributes :orderID,prodID,custID,quantity,unitprice,totalprice-calculated query column where primary key was set to orderID,prodID,custID

But I got some errors while trying to deploy the cube like

Internal error : The operation terminated unsuccessfully.
The datasource,'Test_cube', contains an ImpersonationMode that is not supported for processing operations.
Errors in the high-level relational engine.A connection could not be made to the datasource with the DataSourceID of 'Test_cube',Name of 'Test_cube'.
Errors in the OLAP Storage engine: An error occurred while the dimension, with the ID of 'products',Name of the 'products' was being processed.
Errors in the OLAP storage engine: An error occurred while the 'prodID' attribute of the 'products' dimension from the 'Test_cube' database was being processed.

Try this

Double Click on your data source under solution explorer -> Navigate to Impersonation Information tab -> Choose inherit
