I CAN SEE ALL SHIP TO LOCATIONS FOR THE CUSTOMER EVEN IF I SELECT ONE BILL

Question

Dear,
I CAN SEE ALL SHIP TO LOCATIONS FOR THE CUSTOMER EVEN IF I SELECT ONE BILL TO
Steps:
Create customer name "customer 1"
Under this customer, I create 2 new address
"Customer A " with tow business purpose
1-bill to –> customer A
2- ship to-> customer A after that I link ship to with bill to customer A , I CHECK THE PRIMARY SITE CHECK BOX
FOR THIS SITE
"Customer B" with tow business purpose
1-bill to –> customer B
2- ship to-> customer B after that I link ship to with bill to customer B
Now when I navigate to (N) Order management ->order organizer ->new order
I select the "customer 1" from customer field name I tab to other field bill to
location it is coming by default as primary site customer "customer A"
I OPEN THE LIST I SEE tow customer A AND B I SELECT 'B' AS bill to
When I tab to the other ship to field in also I can see the tow customer " A" and "B" but in real
setup I link the customer "B" WITH ONE SHIP TO ALSO CUSTOMER"B" WHY I CAN SEE
ALL LOCATION FOR THE CUSTOMER EVEN IF I SELECT THE ONE BILL TO .
WHAT THE BENIFIT FROM LINK CUSTOMER SHIP TO FIELD WITH BILL TO IF I CAN SEE ALL LISTS
FOR CUSTOMER SITE
Expected Behavior:
Once I link the ship to location with bill to location I must see when create sales order only the ship to location
link with the specific bill to already specified
Business impact:
This give the user entry ability to enter wrong data or give him the confusion any site I must enter
thanks

Answer 1

That is expected behavior.
You can see the all addresses of account in the list as long as the purpose condition is satisfied. Linking is only for defaulting and not for controlling. If you do not want to see you can create a different account for the B address.
