Do you need a git Blame! feature for your sys_update_version?

[Igor Kozlov]

I some of your changes are not scoped or you need to find creator of some old old you will step on the problem: Created By field is actually showing the user who applied the update set, not one who modified the script.

My suggestion is no add a calculated Blame! field to your sys_update_version  and  sys_update_xml tables.

The code it pretty simple:

(function calculatedFieldValue(current) {

	return findLastUpdater(current);

})(current);

//current - sys_update_version or remote update
function findLastUpdater (current){

var xmlString = current.getValue('payload');

var xmlDoc = new XMLDocument2();
xmlDoc.parseXML(xmlString);
var userName = xmlDoc.getNodeText('//sys_updated_by');

if(!userName) return ""; //reasonable on upgrade and some  edge cases

//modify if you would like to use String, email, etc instead of reference
var gr = new GlideRecord('sys_user');
gr.get('user_name', userName );

return gr.getUniqueValue();
};

See result at screenshot - script was always changed by same person, even Created by show 3 different users
