NULL rows inserted in SQLServer

We’re using WM 6.0.1 / SQLServer 2000 / MS SQLServer 2000 JDBC driver and have a process calling a basic insert adapter service.

When testing the insert adapter services from the Developer individually, they insert correctly. However, when the process is run, records containing null values are being inserted with no error returned. We’ve confirmed via WmMonitor/pipeline that the correct values are reaching the adapter services.

Any help on this would be appreciated !
