How to know if a field was modified in a form through a business rule?

[Mauricio Guzman]

Hello, I need a way to know through a business rule if a field was modified, this will be checked every time I save the form or send it

I tried to use the functions of this web page, but it seems that they no longer work at the moment

are you looking for any specific field or all fields?

In BR what happens if you use this?

I'm looking for all fields

you can try something like this?

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


   var gr = new GlideRecord('sys_dictionary');


   gr.addQuery('name=incident^ORname=task^element!=NULL'); // Replace 'incident' by the table that is relevant to you


   gr.query(); 


   while (gr.next()) { 


     if (current[gr.element] != previous[gr.element] ) {


         gs.addInfoMessage ('Field ' + gr['name'] + '.' + gr.element + ' has changed!' ); // Insert your here code to save log where you want


     }   


   }


})(current, previous);
