Project Billing: Project for customer with multiple Ship to Sites

 Hi Guru's

We have problem here; we would like to associate one project to different ship to sites for the same customer. The billing address will be same for all the customer definations only ship to address will be different.

In this particular scenario since the customer is same the system does not allow me to create more than one record against customer on the project. it gives me Unique name constraint error this is crazy it is very much possible in real life scenario.

Any Idea's???

Gautam
