Handling HANA input parameter in SAP BO Design Studio

Dear all,

           I have an input parameter defined at my HANA view. I am consuming the same view in Design Studio.

          For eg: User Id is assumed here as the input parameter.

          I have got the solution how to set an input to the placeholder with the user id .

VAR A=(APPLICATION.setVariableValueExt(input parameter name,DS_1.getinfo  ().user))

          But I am not able to find out how can I filter my chart with the same data source  with this input parameter being set .

       In web intelligence,we can easily handle this by creating a derived table.

         It will be very helpful if anybody can help me regarding the filtering part?

Regards
