Forum Post: RE: I added same field in all customers form and sales order . In sales order form field value should come from customer form.

I'm trying for same requirement in vendtable(all vendors) and pruchtable (all purchase orders) but I'm getting error while creating new purchase order "object reference is not set to an instance of an object". Here in this requirement I need to change the code or some other process. Can you give an idea for this Kind regards
