Create Relationships in CRM 3.0 programmatically

Ever have the need to programmatically create a relationship between contacts or between a contact and an account?

I stumbled on this problem when a client requested that I import relationships from the legacy ACT! 6 database.
The field where [Lead source] and [referred by].

The relationship entity schema name is "customerrelationship".
The entity has the following important attributes:

Attribute	Description
customerroledescription/partnerroledescription	The description for the relationship
customerid/partnerid	The Lookup for the customer and partner respectively
customerroleid/partnerroleid	The lookup for the relationship role (This can be configured in the Settings section of CRM)

It is that simple, create your class than call the service.create method of the CRM 3.0 to create the relationship.

Have a great day.
