SAP MDG difference between Vendor UI and Supplier UI

Hi,

Does anybody know what is the difference between Vendor UI and Supplier UI in SAP MDG-S? Is there a blog/article that shows the difference in UI?

MDG-S config guide says this.

MDG-S offers two different groups of change request types that support either the supplier UI or the vendor UI. Only one of these groups should be used. If you intend to use the vendor UI as alternative to the supplier UI proceed as ...........

I would like to know what is the difference specially in UI screens, so we can go for the one what suits us better.

Thanks
