Brian,

Actually, you don't need to manually handle the transactions because MM .NET takes care including parent, child, grandchild, etc. objects in a single transaction for you. All you have to do is register the child objects and they will participate in the same transaction.

To have this feature kick in, set your business objects' AutoSaveOnParentSaved property to true (you can do this at the ABusinessObject level).

The Save() method returns an enumerated value of type mmSaveDataResult. If it is equal to mmSaveDataResult.RulesPassed everything went well in all business objects. This is because broken rules automatically bubble up the reference chain to the parent object's broken rules collection. For more information, see the MM .NET Help Topic "Establishing Business Object Relationships".
