For CRM 7.0 in shopadmin settings > In Transaction tab > we have a field called RFERENCE CUSTOMER. This field is mandatory and we need to maintain some BP number, otherwise it does not allow me to create shop.
Why should any client restrict their business for one SOLD-TO only?
(Till CRM 2007, this reference customer field was not there. Becuase of this we able to create orders for as many customers as we want.)
