I added enum field in all customers(CustTable) form and sales order(Sales Table). In sales order enum field value should come from customer master for the associated customer for the sales order

Create a enum field named as "ABC code" and create enum value as below and Add this enum field in the customer master in general tab -

a) None b) A C) B D) C

Add ABC code in the sales order and this value should come from customer master for the associated customer for the Sales order.

Can you please help me
