Supplier self registration in SRM 7.01 EHP1 SP5

Hi SRM Gurus,

We are trying to configure Supplier registration in 7.01.Do we require separate client for supplier registration?

  It is understood that webdynpro ABAP application is used for supplier registration from 7.01 EHP1.

We are able to get the supplier self registration screen. And once clicking on SEND button, the following error mssg:

u201COrganizational unit 00000000 does not exist; check your entries,

Error while creating organizational unit; inform system admin.

Error occurred while locking organizational unit 00000000.

We have configured both vendor organization structure as well business organization structure. We are following the SAP document: SAP SRM 7.0 EHP1 Supplier Qualification. Document describes about setting up supplier registration with customizing switch and the other is without customizing switch.

Are we missing configurations anywhere in supplier registration client or EBP client?

Thanks,

Babu
