Dear Mr. Solaiappan,
If you have not received challan only(document), you can take another copy and send it to jobworker. the jobworker fill the necessary field and return to you with their delivery challan. That the case you can not reverse the duty.
Otherwise, you have not received the material from job wroker within 180 days from challan date, you have to reverse the cenvat duty of input material, which was taken at the time of inward.
