Answer 1

Can you provide me some more detail about your self register functionalty.
Self-register functinalty is B2C standard functinality as user register him self through register form and create his account in backend.
For B2B you have to create customer first then contact person and then link it to Su01 user through reference. Now you give this su01 user id to your B2B customer to login to B2B ISA.
As per my knowledge B2B does not provide this kind of Self Registeration functionalty. For B2B you have to create customer first then you can link that customer with SU01 user id through Contact person.
You can create custom form to collect information which your client require to open a B2B account for existing customer. When your client receive this form data in email they can create the B2B isa ccount. for Already existing customer.
Note:- For B2B, customer must exist in the Backend then you can create Internet user.
Thanks and Regards.
