What roles need to use JAVA System configuration

Hi all,

I need to create a new user for reading configuration parameters in my Java stack with 7.30 version. I can't use visual admin, so i'm using NWA.

What roles i  have to give him?

I tried to create a new role and assign tc~lm~itsam~ui~cfg_props~wd action, but it didn't help me.

You can JAVA system configuration here:

Go to ip:port/nwa -> Configuration -> Infrastruture -> Java System properties

or just use this url: ip:port/webdynpro/resources/sap.com/tc~lm~itsam~ui~mainframe~wd/FloorPlanApp?applicationID=com.sap.itsam.cfg.java.systemproperties&applicationViewID=systemproperties

Please, help me
