Hi, 

I need close a child case with all included assignments through an activity.

I use this activity in a service that's not necessary be authenticated.

I've trying use pxForceCaseClose but doesn't works. I also save this activity and all activity inside than that needs authentication to run and I unmarked the option to require the authentication . but don't works. 

Scenario: 

PaternCase create a lot of child cases, the service update the child case and the father case and close the child case.

There is have more possibilities to close a case using an activity?
