Help! How to react on UNSAccountInUNSGroup (events don't work)

Hello everyone

I would like to react on each insert and delete in the proxy view UNSAccountInUnsGroup.

The reason is that I don't won't to care if the assigment is done for an SAP, UNSB ord AD Entitlement.

But I've found out that triggers on the view do not work.

So it seems, that I need to do it for each target system type.

But than I'll have the next problem with SAPUserInSAPRole. Since this Table is consolidated in HelperSAPUserInSAPRole I wan't to base on that Helper table.

Es well there, it was not possible to react on events.

Do you have any suggestion how to deal with that?
