In SuiteScript 1.0 we know there is nlobjRecord.createCurrentLineItemSubrecord('sublis tid','fieldid') which gives you access to the subrecord. It also doesn't require you to select a newLine. You set the fields with setFieldValue and at the end you use .commit(); to save the subrecord.

In SuiteScript 2.0 createCurrentLineItemSubrecord() doesn't exists. I am able to get the subrecord object by getCurrentSublistSubrecord(). However I am not able to selectLine or selectNewLine without getting a INVALID_SUBLIST_OPERATION. So I opted to not select a line and after setting all the fields there is NO .commit().

Has anyone attempted to create a customer record and add a address before saving the record? If you have you been able to set the address field (addr1, city, state, zip, country)?
