Edit Dataverse table record error: It is not possible to change transferred line.

I have a dataverse table that was populated using Dual-Write and a D365 F&O entity.  When attempting to edit a record directly on the dataverse table, I get the following error: 

There was an error in saving this record. Unable to write to Finance and Operations apps due to following error(s): {"Write failed for entity VER_SMAServiceOrderLineEntity with unknown exception - It is not possible to change transferred line.\nvalidateWrite failed on data source 'SMAServiceOrderLine (SMAServiceOrderLine)'"} Please rectify your data and try again. If issue persists after multiple retries, please contact your system administrator.

This error is coming from the 'validateWrite' method on the SMAServiceOrderLine table because the service order is in a 'Posted' status.
