HANA XS - $.trace - cannot find traces

Hi,

I have tried to use API $.trace inside my HANA XS project but cannot get any trace out of it.

I have followed documentation at Development Guide on how to configure and look for the traces files, but cannot get anything on xsengine trc file:

My HANA version is 102.3 and I’m using SYSTEM user.

I have debug and development_mode active on that server.

Debug works fine.

What can be missing?

Thanks,

Trinidad.
