Hi Atul,
Other than using the workflow type for checking the schedule or start conditions , you can also use the BADI based check.
In the last screen shot under "Action determination and action merging" you can set this in the box where you have setup "Workflow condition" .
Then you have to implement the badi : EVAL_SCHEDCOND_PPF with a filter value. Here you can right your own logic to evaluate whether the action should get scheduled or not.
