Hello Viswanath,
during standard vendor replication from ECC to SRM, Bidder Business Partner role (BBP001) is created at the same time that the Vendor Business Partner role (BBP000).
Nevertheless, you need to create Bidder data (check /SAPSRM/CL_PDO_MO_BP_BIDDER class), then the Contact Person (check /SAPSRM/CL_PDO_MO_BP_CONT_PERS class given by Ivy).
Regards.
Laurent.
