Limit programmatically the timeframe of stored procedure execution

Hello,

I'm calling a stored procedure from XS Java script code.

I want to limit programmatically the execution by setting timeout so when this timeout will over, rollback will be executed and
the stored procedure will return appropriate value (handle timeout event).

I'm using HANA SP06 v.1.0.60

I found this related post http://scn.sap.com/message/10880763#10880763

but is from 2011 and "SYS"."M_CONNECTIONS" doesn’t live here anymore.

Any advice will be much appreciated.

Best Regards,
