Sales Order creation with Ship to not assigned to Sold to

Hi There,

I have an issue that I am able to create an order with a Ship to which is not assigned to Sold to. i.e, The sold to accepts any ship to and not giving any error. I am giving both Sold to and Ship to together while order creation. Is it because of this? Should I enter sold to and then press enter for the list of Ship to's assigned to that? I dont find any issues in the Partner determination.

Can you help?

Thanks in advance,

Renjith
