The issule I meet is that:
1 Whatever dismode( N,E,A ) I use,it can not popup the first screen (select the bussiness partner),only popup at the first time.At the second time,it will not popup,only get the bussiness partner same as the first time.
2 It can not process the ok_code of click 'BACK' button in the top toolbar and can not display the save ok_code in A dismode.
3 I want to run the bdc with a internal table loop,but at the second time,it stops,not run continuely.

Hi,
Sorry but i have demo program for this Bapi.
But you can try to make a small to test it,
put business partner as parameter;
Then first call Bapi 'BAPI_BUPA_ADDRESS_GETDETAIL' that will retrieve all informations
Then after you can call 'BAPI_BUPA_ADDRESS_CHANGE' to change one field
    if you look at the tables you BAPIADSMTP and BAPIADSMTX for email adresses,
                                             BAPIADTEL and BAPIADTELX for phones ......
   in  BAPIADSMTP you fill the values, in BAPIADSMTPX you have a field called UPDATEFLAG (I for insert, U for update , D for deletion) and for other fields you flag it if you to take them into account.
If necessary (it's different depending on Bapi ) you must call Bapi 'BAPI_TRANSACTION_COMMIT' if the commit is not done in  'BAPI_BUPA_ADDRESS_CHANGE' .
I hope it will help you.
