Associated an iStore User to an existing Account Number

If you are looking to link an iStore user to an existing Account number, you may wonder what is the big deal about it - entering the Party Id (which is equivalent to customer_id in the fnd_user table) in the Security –> Users form should suffice. If only that was the case.
There is one key table that requires to be populated and I reluctantly mention it here, that a simple insert into this table will do the magic for you.
CustAcctRole.assignAccount(conn, partyId, accountId, “A”);
