Multiple BP for same vendor in SAP SRM

Hello SRM experts,

We have an issue in our SRM 7 system where in during the replication of vendor from backend, the system has generated two BP numbers for one vendor in the backend. We are not sure of how and why this was generated.

Ex:

BP no     Vendor no

XXX23       XXX464

XXX24      XXX464

Thanks,

Vipra.
