Query related S/4 HANA

Hi,

I am having more than 15 yeas of IT experience with 13 years of experience into SAP-ABAP/BI. I want to switch to S/4 HANA to upgrade my existing skill. But I am not interested to be in technical side. I would like to go into a business modules which is more of design kind of role.

Can you please specify which area of S/4 HANA, I should concentrate which would have great demand.

Thanks!

Winston
