Assigning custom roles after vendor registration

Hi Experts,

We have implemented SRM 7.0 Ehp3 with SUS. We are developing the Vendor self registration functionality. After the vendor registration is approved system normally assigns pre-defined standard roles.

Now we have created custom roles by copying the standard ones and have re-generated the authentication profiles.

But now when the vendor registration is approved none of the custom roles are getting assigned to the vendor user.

Could you please help on how to get the custom roles assigned to the vendor instead of the standard ones.

Regards,
