Modifying xvbpa

Question:
I am working on an user exit. I have to modify the partner functions ZH and ZE in xvpba depending on entries in a Ztable. Now if I modify the kunnr value in xvbpa the other fields like adrnr, land1 , name1 etc also ought to be changed. How do I know which fields in xvbpa should be filled when partner function is ZH? All suggestions are welcome.
