Tds on reimbursement of conveyance expense payable to professional

Dear experts,

Our consultants charged Reimbursement of Conveyance expense in the same bill of consultancy fee by showing it as a separate part in the bill (Part A - Consultancy Fee, Part B-Reimbursement of Conveyance). They calculated service tax on total amount including the reimbursement. On which amount i have to deduct TDS under section 194 J, Consultancy fee+Conveyance or only on consultancy fee ?

Thanking You

Jerry
