getting error when integrating the user into org structure

Hi'

I have created a SU01 user record. using users_gen report and option "create users from SU01 record" ia m trying to integrate this user into a Org structure.

I am getting an error saying "Creation od object ID 00000000 is not allowed".

I have checked the consistency of the orgunit to which i am trying to integrate the SU01 user. i have checked this using bbp_check_consistency. Everything seems to be ok.

Whatever org id i select i am getting the same error.

can anybody help me out?/

Thanks in advance
