Here is the explanation.
1.Line number 3 checks if there is an asset property in target record
2.Line number 4 create a variable a and initialises it with a Glide record object referring to alm_hardware table
3. Line number 5 fetches the hardware asset record.
4. Line number 7 create a variable l and initialises it with a Glide record object referring to cmn_location table
5 Line number 8 gets the cmn_location record where u_site_number is same as u_room_number property of the source record.
6. Liner number 10 assigns the value of cmn_location sys_id to the location property of variable created in step number 2.
7. Line number updates the glide record variable a.
Also, you can update the code as follows to map the location correctly.
(function runTransformScript(source, map, log, target) {
if (target.asset) {
var a = new GlideRecord('alm_hardware');
if (a.get(target.asset)) {
var l = new GlideRecord('cmn_location');
if (l.get('u_site_number', source.u_site_number)) {
a.location = l.getValue('sys_id');
a.update();
}
}
}
})(source, map, log, target);
