COPA datasource for BW4HANA with S4 as source

Hi guys,

Just wanted to check what datasource or how do you create the datasource for COPA in BW4HANA with S4HANA as source?

Do you still use the KEB0? Do you use CDS view-based datasource? If it is the latter, what CDS views did you use? Or how do you do it?

Thanks.
