Hi @Lkowalski your BR should be on sc task table

share your updated script here to check

Hello @Lkowalski ,

Please make sure business rule is on sc_task table. And the when to run conditions are satisfied. 

If it is not working for you, please share the screenshot of your conditions and the script as well.

Regards

Siddhesh

SCRIPT:

(function executeRule(current, previous /*null when async*/ ) {

   var ritmGr = new GlideRecord('sc_req_item');
ritmGr.get(current.request_item);

switch(current.state.toString()) {       
case '1': //Pending
ritmGr.state = -5; //Pending  
break;
case '2': //Work in Progress
ritmGr.state = 2; //In Progress
break;
case '3': //Awaiting Customer
ritmGr.state = 6; //Awaiting Customer
break;
default:
ritmGr.state = current.state;
}

ritmGr.update();

})(current, previous);

Hello @Lkowalski ,

Looks like your issue is resolved. I will suggest add one more condition in your when to run as, "State changes". It will avoid the business rule to run unnecessarily. Let me know what you think.

Cheers,

Siddhesh
