Domo's NetSuite Writeback connector supports the creation or most types of records. However, some record types are missing. For example, work order completions are missing but could be created if a "transform" operation on the existing "work order" object was possible in the writeback connector.
It would be great if some option could be included with the existing NetSuite Object types to use a transform method, or alternatively if the list of supported objects could be expanded to include work order completions.
