ServiceNow get record last updated fields - GLOBAL scope

(for scoped app version see this article )

see https://www.servicenow.com/community/developer-forum/where-does-the-glidescriptrecordutil-come-from/m-p/1441264 

and http://snamigos.blogspot.com/2017/11/how-to-get-changed-or-modified-fields.html

notes:
- may not work in scoped applications

copy below into an after business rule on incident update for example:

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

    gs.addInfoMessage('test br');

    gs.include('j2js');

    var gru = GlideScriptRecordUtil.get(current);

    var sChgFields = gru.getChangedFields();

    //var sChgFieldsNames = gru.getChangedFieldNames();

    //var sChg= gru.getChanges();

    gs.addInfoMessage(sChgFields);

    //gs.addInfoMessage(sChgFieldsNames);

    //gs.addInfoMessage(sChg);

})(current, previous);

script include version - additional features:

   

  this.si.getIncidentLastUpdatedFields(current);

 

getIncidentLastUpdatedFields: function (incGR) {

         

        try {

 

gs.include('j2js'); 

            var gru = GlideScriptRecordUtil.get(incGR);

             

             var changedFields = gru.getChangedFields(); //Returns an arrayList of changed field elements with friendly names

 var changedFieldNames = gru.getChangedFieldNames(); //Returns an arrayList of changed field elements with database names

 var changeds = gru.getChanges(); //Returns an arrayList of all change values from changed fields

gs.info("changedFields: " + changedFields.toString());

    gs.info("changedFieldNames: " + changedFieldNames.toString());

    gs.info("changeds: " + changeds.toString());

           

   var changedFieldsF = j2js(changedFields);

   var changedFieldNamesF = j2js(changedFieldNames);

   var changedsF = j2js(changeds);

    gs.info("Changed Fields: " + JSON.stringify(changedFieldsF));

    gs.info("Changed Field Names: " + JSON.stringify(changedFieldNamesF));

    gs.info("Changes: " + JSON.stringify(changedsF));

   

        } catch (ex) {

            gs.info('ERROR'+ex.toString());

        }

    }
