TDS certificate form 'J_1IEWT_CERT'

Hi Experts,

I need to add 'street 4' and 'street 5' field in vendor master to be printed in the TDS certificate which has form name 'J_1IEWT_CERT'. But these fields are not present in the table vendor master table 'LFA1'.

In which table i can get these fields and be added to the sap-script form.

Thanx

RR
