How can you add the parent number to a brand new Customer or Supplier not currently set up in Addres

<Q>How can you add the parent number to a brand new Customer or Supplier not currently set up in Address Book at the time of entry in the Supplier Master/Customer Master on release A91 and above?

Basically if its a brand new address book record you are entering through the customer or supplier master you can add the parent number at the time of entry but just not on the supplier master screen, when you hit enter the window P01AB will pop up and up will enter the address book information like mailing/alpha name, street address and etc.. plus the parent number if you wish.
