After you deploy the filters to Unwired Server, synchronize data and ensure that filters are performing as you expect.
- Confirm that the columns appear correctly after the filter has been added to the mobile business object. - Refresh the object.
- In the Properties view, select the Attribute Mapping tab.
- Verify that columns are  correctly listed in the Map to column.
 
- From the device client or the device simulator, open the mobile object, and check that the new column appears.
- Synchronize the object from the device client or simulator.
- Troubleshoot filters if issues arise:- During synchronization, all System.out statements are printed to the Unwired Server log. 
- If you started Unwired WorkSpace with the -consoleLog in java.exe, System.out statements are also  printed to the console window.
