How can I have a Business Rule call a Script Include?

smorri · ‎09-20-2018

I have a Business Rule that takes part of the short description (a location), and puts it in our location field. This works from an email with subject Button Press - Laptop Laptop - UH07311. The Business Rule works. Further below is a script include that handles all of our routing for different Desktop Technicians depending on location, contract, etc... The script include is called by client scripts. Is there away to call it on the server side as well?

(function executeRule(current, previous /*null when async*/) {
var str = current.getValue('short_description');
var loc = str.substr(30);
if(str.indexOf("Button Press - Laptop Laptop -") == 0)
{
current.location.setDisplayValue(loc.trim());
current.cmdb_ci.setDisplayValue('Desktop MW');
current.u_incident_type.setDisplayValue('Fault/Failure');
current.u_issue.setDisplayValue('Other');

}

})(current, previous);

Script Include below:

Your Script Include is a client-callable SI. It doesn't work the same when called server-side, if I'm not mistaken. Try making a non-client-callable version, and have the client-callable one invoke it for GlideAjax.

function onAfter(current, previous) {
       var scriptInclude = new nameOfScriptInclude();

       scriptInclude.scriptIncludeFunctionName();
}

Its absolutely possible to call a script include from a Business rule.

If you are making a call from the server side then parameter passing is different than GlideAjax.

So change the starting part of your script include to the below lines of code

incidentRouting : function(ci,location,issue,unit,contract,workarea){
		//couldn't get the object to pass in, so rebuilding object to keep flow.
		
		var json = new JSON();
		
		var routingInfo = {};
// This way you use GlideAjax from Client side and Call this function from Server side too
			routingInfo.ci = ci || this.getParameter('sysparm_ci');
			routingInfo.location = location || this.getParameter('sysparm_location');
			routingInfo.issue = issue || this.getParameter('sysparm_issue');
			routingInfo.unit = unit || this.getParameter('sysparm_unit');
			routingInfo.contract = contract || this.getParameter('sysparm_contract');
			routingInfo.workarea = workarea || this.getParameter('sysparm_workarea');

The way you will call this function from a Business Rule would be

var obj = new utsw_AJAXAssignmentRouting();

obj.incidentRouting(your parameters);

Hi Aman,

I made the changes to the script include and added a second business rule as below, but the second business rule below is not firing off. What am I missing?

When - after insert/update

Business Rule

(function onAfter(current, previous /*null when async*/) {
var obj = new utsw_AJAXAssignmentRouting();
obj.incidentRouting('sysparm_location');

})(current, previous);

Okay. I should have been more specific about the function call. Below is the mistake you are doing

Correct: var obj = new utsw_AJAXAssignmentRouting();
Wrong : obj.incidentRouting('sysparm_location');

The function in the script include expects 6 parameters to be passed in an order as described below

incidentRouting : function(ci,location,issue,unit,contract,workarea){

You should change your script to something below to pass the parameters (this is just an example and the below script will not work)

(function onAfter(current, previous /*null when async*/) {
 var obj = new utsw_AJAXAssignmentRouting();
//Pass your parameters in an order as your scriptinclude function expects them. 
//I made up the colun names, please replace them with the correct names.
//Also, if a field is a reference field, current.u_coulmn will give you the sys_id, use dotwalking if you need to get into specific values of the referenced field 
 obj.incidentRouting(current.cmdb_ci,current.location,current.u_issue,current.u_unit,current.u_contract,current.u_workarea);
 
})(current, previous);
