How to grant permission to change xsengine trace level.

Hi Folks

I have question regarding granting permission to a user to let him change trace level in the xs_engine traces.

When he tries that in Web IDE, he gets

10:22:26 >> Error reading Trace File: insufficient privilege: Not authorized

10:24:14 >> Error reading Trace File: insufficient privilege: Not authorized

Looks like the user needs permission to execute the following

exec 'ALTER SYSTEM ALTER CONFIGURATION(''xsengine.ini'', ''SYSTEM'') SET (''trace'', ''xsa:sap.mobsec.monsoon'') = ''debug'' with reconfigure';

What permissions should I grant the user so that he can do this successfully.

Hana Version I am using:

HDB version info:

  version:             1.00.85.00.397590

  branch:              NewDB100_REL

  git hash:            not set

  git merge time:      not set

  weekstone:           0000.00.0

  compile date:        2014-11-12 12:39:22

Appreciate your time.

Thanks
