Run-time Global Variables from Run_Batch_Job are not passed to JOB.

We are upgrading to SAP Business Objects Data Services from 12.2.1.2 to 14.1.1.210. We are invoking a Job/Data Flow via web services Run_Batch_Job method. It works fine in 12.2 but it 14.1 the global variables are not passed to job and we are getting the below error

(14.1) 03-04-14 22:54:32 (E) (3804:0884) FIL-080131: |Data flow JOB_NAME_1

The variable <$OUTPUTFILE> of the file loader is empty. Initialize the variable to a valid value.

(14.1) 03-04-14 22:54:32 (E) (2584:3648) FIL-080131: |Data flow JOB_NAME_1

The variable <$OUTPUTFILE> of the file loader is empty. Initialize the variable to a valid value.

I am thinking it might be a setting we missed. Can some one point me to solution for this problem?
