CRM Leads

Hi ,

We need to create the CRM Leads from an other System , find and assign the correct Contact Business Partner based on the e-mail address we do receive from the other System .

Do SAP CRM lead functionality has the capability to do a contact match and assign the correct contact BP ( the customer BP will be the one linked to the contact BP) . And to create a new Contact Business Partner if no match was found ?

Any help is welcome , thank you .
