So I have dug through every schema and sap delivery unit installed on our on-premise appliance (SPS09) as well as scouring the SCN forums but I have found no further information on this...
I have seen the different API's HANA offers (fie, job,etc) and the different stored procedure that the system uses but I have not found any clues on how I would go about creating an XS application that could achieve my goal.
Ideally the XS application would be able to allow a user to login (with necessary roles, etc) and execute the HALM functions that you normally have to do through the SAP life cycle manager interface on studio or the XS/LM interface (view open/approve/release/transport changelists) .
