Well, yes thats posible but i think that you will need to call odata services to do the actions in SAP and i think odata services can be linked to BAPI execution or query to get data.
I need to start testing thinks like that but my client is still using classic SAP/R3 versión.
In any case, if you want to learn more about that, you can check the OPEN SAP courses. There are a lot of trainings related to HANA
