To display on the contact details We need to get the login details from the code and we can pass that value to the live order or we can check that with the custom field.
create a custom field in the sales order and add that to a configuration record.

Then set that variable to a love order model then it will set the value to the sales order ,i have done this with the help of a saved search.
