PO from SRM to supplier via PI 7.1

Hello Experts,

I have a scenario where I need to send PO request from SRM to PI 7.1 via proxy and then from PI 7.1 to third party supplier via HTTP port.

I have imported all the ESR objects from market place and are available in my ESR. Many scenarios are there with many Integration process, actions and all.

Now I am confused which one to use from the above available scenarios during the creation of integration scenario in ID. Since my scenario only needs to send PO create, change and cancellation request.

Please suggest,

if I have use Service_Procurement_SupplierEnablement from ESR

or I have create manually the configuration with only oubound interface Send_PurchaseOrder_out.

I appreciate your help.

Thanks,
