CIG integration for Sourcing Request (QuoteRequest) - how manage Access Control

[S0022095933]

Hello

we configured standard integration from S4Hana to Ariba Sourcing Suite of RFQ --> Sourcing Request (QuoteRequest process in CIG). however, the Sourcing Request created from that integration from S4Hana is "open to everyone" since the default taken from the Sourcing Request Template (standard) is Access Control = Private to Sourcing Pro users

since manuals do not help on this, we would need your expertise to understand what is possible to configure with Access Control. Please consider that requirement from Client is to restrict the visibility to a specific cluster of users INSIDE the Sourcing Pro Users list.

We have also another requirement: be able to configure 2 Sourcing Request Templates used in the integration: in this way 2 Clusters of buyers (let's say Buyer List A and Buyer List B) are not able to see the other cluster list of Sourcing Request created from integration. Not sure if that kind of requirement is solvable with 2 Sourcing Request Template used in QuoteRequest integration (and how to make integration choose 1 on the two when sendind) or with some other way on the Standard OOB Sourcing Request Template itself.
