This update to Data Sync allows you to filter the SQL Providers to return a subset of data without loosing the ability to write back to the data source. The current filter option involves writing your own SQL Command however this prevents write back to the data source. Now you can supply your own WHERE clause as a separate parameter on the configuration instead and we just append it to the query we build. Therefore now you can sync a subset of data stored in a SQL Table.
This update is available in Data Sync Studio version 3.0.356
