Frank,

That seems about right. Make sure you also add to the child business objects the following in the HookConstructor method:

protected override void HookConstructor()
		{
            this.AutoSaveOnParentSaved = true;
            this.AutoCancelOnParentCancel = true;
            this.AutoDeleteOnParentDeleted = true;
            this.AutoEmptyOnParentAdded = true;
            this.ForeignParentKeyField = "insert FK here";
		}

The only time the above code is used is when you use the RegisterChildBizObj method.

Don't know the difference between SaveEntity and SaveDataSet as I always use SaveEntity.

Bob

mmSaveDataResult result = oPolicyHeader.SaveEntity();
