When deleting a group of devices, this error message occures :

Failed to delete device group.

Error = 80040E14

ErrorMessage=IDispatch error #3092

Description=[Microsoft][ODBC SQL Server Driver][SQL Server] the DELETE statement conflicted with the REFERENCE constraint "FK_WebUser_nHomeDeviceGroupID".The conflict occurred in database "WhatsUp", table "dbo.WebUser", column "nHomeDeviceGroupID"

.......................

So, What Can I do ? I can only move this group to another group and rename it ...but nothing Else.

How to delete it ?

I use WUG V12.0

Christophe.
