@Bibek Shrestha It looks like you'll need to access the contacts as a sublist on the customer. Generally, I'd recommend using a search with the opportunity. But it does work like this if you have the customer loaded:

var myContact = CustomerRecord.getSublistValue({ sublistId: 'contactroles', fieldId: 'contact', line: 0 });

Wouldn’t this give me contacts related to the customer and not the opportunity?

It would. You could take the same approach on the Opportunity record though. You can use .getSublistValue to get a value from the sublist rather than .getSublist

I already tried

.getSublistValue

,

.getSublist

,

.getLineCount

None of them work Strangely

.getSublists

lists

contacts

as one of the sublists

Hmmm. I'm seeing the same. Is the list of Contacts on your Opportunity different than the list of Contacts on the Customer Record?

yup

So is there any reason you couldn't get the list of contacts from the Customer record and not from the Opp?

as I said.. they are different

My apologizes, I read your response wrong

no worries on that

In the example I looked at on my end, there was no difference between the contact list on the customer versus the opportunity. For a search, I like to try to get the search to work in the User Interface, and then export it using this extension: https://chrome.google.com/webstore/detail/netsuite-saved-search-exp/cbpefhoehnbljgflflncaejfmkmofoje?hl=en-US

Thanks for the plugin..

Glad to hear it!
