How the SUS suppliers will access the SRM server for bidding in MM-SUS ?

Dear Experts,

We are configuring the MM-SUS scenario in our SRM 7.01 scenario.

Initially, we replicated the SUS vendors from the SRM server by checking the 'portal vendor' tick in the SRM system. The system creates SUS vendors who has access to the both SUS system and SRM system.

However, we need to replicate the vendors from MM system only using BD14 to SUS. It will generate the SUS vendors with access details for SUS system. But, we are configuring  our online bidding/auction only in the SRM system. How will the SUS vendors get access to the SRM server to take part in the online bidding activity?

Could you please guide me with your experience?

Thanks and regards,

Ranjan
