Is it possible to access the tracking url of a particular tracking number from the Package Tracking Number field in an Item Fulfillment's Package sublist?

I could be wrong, but I don’t believe that is stored anywhere in the database. I think it’s calculated automatically when you view the transaction in NetSuite. We build our own tracking links when we send emails based on the prefix of the tracking number.

thank you for response! could you share how you create your own tracking links?

After looking back at the code, I see that we’re not actually using the prefix in NetSuite. That must have been our old system. Now, we are use the carrier type and we use a little function like the one below to get the tracking URL and then just append the actual tracking number on the end.

function trackingURL(carrier) {
        var url;
        switch(carrier) {
            case "UPS":
                url = "<http://wwwapps.ups.com/etracking/tracking.cgi?TypeOfInquiryNumber=T&InquiryNumber1=>";
                break;
            case "FEDEX":
                url = "<http://fedex.com/Tracking?ascend_header=1&clienttype=dotcom&cntry_code=us&language=english&tracknumbers=>";
                break;
            case "DHL":
                url = "<https://webtrack.dhlglobalmail.com/?trackingnumber=>";
                break;
            default:
                url = "<http://trkcnfrm1.smi.usps.com/PTSInternetWeb/InterLabelInquiry.do?strOrigTrackNum=>";
        }
        return url;
    }

this is awesome, thank you!
