NW version dependencies between the backend and the Front End Server for Fiori

Hello Experts,

We are in the process of planning for a FES for Fiori (Hub deployment) in our landscape. While our backend ERP Systems are on SAP NW 7.4 SPS 14, we wanted to decide the right NW version for the FES. While we plan to run the dependency check in SolMan, are there any known dependencies or rather compatibilities published?

We are looking for specific guidance on this combination - Backend ERP Systems on SAP NW 7.4 SPS 14 and FES on SAP NW 7.5 SPS 01 / 02. Please advise.

Thanks in advance

Regards

Ramesh
