Ok, i will try this later...
Maybe someone can help me with this error message.
When i synchronize from the mobile device, everything works --> but it is very slow.
When i copy the database from the mobile device to the desktop, and sync this file from the desktop i get the error
"Unable to enumerate changes at the DbServerSyncProvider for table 'CUSTOMER' in synchronization group CUSTOMERSyncTableSyncGroup'."
inner Exception: "SQL Server Change Tracking has cleaned up tracking information for table 'dbo.DRAWMAT'. To recover from this error, the client must reinitialize its local database and try again"
So i when copying the database from device to client and then sync it, there might be an error regareding some clientid or something like that ?!?
