The largest advantage of inline editing is that it executes faster and uses less governance than loading the record, modifying the fields, and saving the record. This works on both standard and custom records. It also involves significantly less code, which is always nice.
Unfortunately, not all fields are inline-editable.
Sublists are not inline-editable; if you need to work with sublist fields, you will need to load the record.
Further, select fields (dropdowns) and subrecord fields (like addresses) are not inline-editable either. To work with these fields, you’ll need to load the record.
Finally, only very specific fields on each record type are inline-editable; to determine which ones are inline-editable, you need to check the ” nlapiSubmitField” column in the Records Browser.
