Bill to party should be pulled from ship to party.

Question

Hi
I have scenario in which I want to pull bill to party from ship to party and not from sold to party in sales order. Business requirement have one sold to party say A . This sold to party has 4 ship to party say B,C,D,E.  Every ship to party has one Bill to party respectively say L,M,N,O.  This scenario is only for one customer and not for all. When ship to is entered in the sales order it should give options to select the bill to party .
I want to know the config steps alongwith the name of the user exit (if it is required for)
Thanks in advance.
James.

Before answering this question, I would like to thank Lakshmipathi for his compliment and James for this interesting scenario.
Lets say your new ship to parties are 90 & 91.
Lets say your new bill to parties are 110 & 111.
So your new requirement is when you enter ship to party 90 or 91, bill to party 110 or 111 has to be determined from sold to party.
Am I correct? That's how I understood your question(If this is not you are not looking for, please advise).
In case yes, you  could do the following.
In your sold to party record, partners Tab, enter the details of your new ship to parties and bill to parties.
In sales order, enter ship to party and system would pop a box listing bill to parties. You can select one of the bill to parties.
Once selected, system would populate sold to party record field.
This is happening because when you enter ship to party record in sales order, system accesses sold to party from ship to party. Once it accesses sold to party, it lists bill to parties available in this sold to party record.
