Need Help with a ServiceNow Business Rule

[Olga -Maria]

I have a ServiceNow business rule that is supposed to set the "warranty_expiration" field of a CMDB CI item based on the end date of a related contract. The script runs without errors, and I can see the log entries indicating that it should be updating the field.

However, the field is not being updated as expected.

I've double-checked the script, field and table names, permissions, and conditions, but I can't figure out why it's not working.

Could someone please help me troubleshoot this issue and provide suggestions on what might be going wrong? Thank you in advance!

Business rule runs on Insert and Update : 

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

current.ci_item.warranty_expiration = new GlideDateTime(current.contract.ends.getValue());

@Olga -Maria 

you cannot set dot walk field

you need to query and then update

var rec = new GlideRecord('cmdb_ci');
if(rec.get(current.ci_item)){
	rec.warranty_expiration = new GlideDateTime(current.contract.ends);
	rec.update();
}

If my response helped please mark it correct and close the thread so that it benefits future readers.

The Business Rule works on the Contract CI table, an m2m table for cmdb_ci and contracts. Does this make a difference? Because it does not work.
