Hi Fatih,
as I wrote the BAdIs BADI_IDENTITY_SU01_CREATE or BADI_IDENTITY_UPDATE do not exist in releases 7.02 and less.
In these old releases we do not have a possibility to prefill user attributes (like parameters) for creating.
In older releases you may use the old exits e.g. the Z_USERS_TRANSFER which you have to put as ID into table SSM_CUST and as PATH you need to put your own function module name.
As example for your function module you may use the function module PRGN_EXIT_USERS_TRANSFER but not need to check for the list of roles in your special case.
But, you need to know that these old exists will not have effect after release 7.02 (if you plan an upgrade) and you need to take care with your implementation not to damage our transaction.
Best Regards,
Holger
