I want to get the changed fields when the SO is edited. However when I get value for 'shipaddress' it always return as changed. I printed and it looks same to me but when I run this command it set changes as true.

checkValues = ["shipaddress","billaddress"]
for(var i =0; i<checkValues.length; i++){
                            if(newRec.getValue(checkValues[i]) != oldRec.getValue(checkValues[i])){                             
                                log.debug(`changed values - ${checkValues[i]}`, `${newRec.getValue(checkValues[i])} - ${oldRec.getValue(checkValues[i])}`);
                                changed = true;
                                break;
                            }
}

Any idea please?

try using

shippingaddress

and

billingaddress

instead? or using

shipaddresslist

and

billaddresslist

to get the address subrecord id then get all the address fields individually and compare them all independently

shippingaddress

and

billingaddress

didn't work

hmm you could also just use a regex and remove all the whitespace from the shipaddress/billaddress maybe that will make them equal again?

Yes I did it and it works
