SAPUI5 oData services and ABAP

Hi All,

I have been practicing and trying to learn the SAP mobile concepts. I have started with SAP CRM Sales App which uses SUP.

I read quite few details about DOE, and enhancement techniques. Then i started learning about SAP FIORI, and concepts of oData.

I practiced few hands on for oData and started learning to develop SAPUI5 UI5 interfaces using eclipse.

Currently I thinking, what does a core ABAP programmer can do with these tools?

Can any one help me to understand which area we should focus for this new Mobile concepts?

Please share your thought.

Thanks,

Praveen
