Hello Bindu,
As a different approach, if you are using PI interface between ERP and CLM for replicating vendor master data trough XML files, you can duplicate standart Vendor XML in PI and modify it for contact data format. By this way PI will drop two seperate files, one is vendor the other one will be contact (Assuming that contact will be dummy, in our case we mapped vendor number as contact name etc.)
This solution is very easy to be applied, I implemented in one customer and did not face any problem.
