Hi Naga,
You can use the PropertyAcessService to read these information.
http://<host>:<port>/XMII/Illuminator?service=PropertyAccessService&mode=list&content-type=text/json
This will give a list of all the properties that can be read.
To read individual properties you could use the mode=retrieve and pass the propertyname as shown below:
http://<host>:<port>/XMII/Illuminator?service=PropertyAccessService&mode=retrieve&content-type=text/json&PropName=IllumLoginName
If you are already using UI5 objects like i5Chart, you could directly access the helper methods.
For e.g to read IllumLoginName you could use i5ChartObj.getUserName() and to read the roles you could use i5ChartObj.getUtilityObject().getLoggedInUserRoles()
Hope this helps.
Thanks and Best Regards,
Ria
