execution error in service

[anitha_s_kumar]

when executing service Rollup I receive the error attached in the image .

Looks like perhaps the context that is executing the RollUp service doesn't have visibility rights to this other service it is calling.

Thanks for the inputs .It helped me resolving the error . Yes I had to correct the visibility rights and also a small correction in the script as I was not using the demo version of Thingworx.

var sysServThingName = "PowerSystemServices" + "_" + username;

corrected the above  statement to 

var sysServThingName = "PowerSystemServices";

@anitha_s_kumar You can refer more information on visibility permissions here . If the issue is not resolved, can you share the script error log for more details?
