Johannes,

I will try to keep this in a function and see if it works. It would be something like:

myfunction();

function myfunction()

{

gs.log("running it");

var items = new GlideRecord('sc_req_item');

items.addQuery('number', 'RITM0011306');

items.query();

while (items.next()) {

  gs.log ("data found " + items.cat_item.name);

  gs.log ("data found " + items.variables.asset_name);

  items.variables.asset_name = 'No Asset';

  items.update();

}

}
