List Sublists Unlike Editor Sublists and Inline Editor Sublists, list sublists are not dynamic. The number of line items are fixed and cannot be removed or added on-the-fly though UI customziation or through SuiteScript. Changes you make to existing line items on list sublists are submitted along with the main record and do not take effect until after the record has been saved. Note that even though you cannot add or remove lines on a list sublist, you can use the UI to change values or SuiteScript to get/set values on lines that currently exist.
