Thank you for your replay.
I have allready tried this and got the same result as you did. The problem is that i still don't know from what subscription, to what new subscription. I can only see that a change has been made.
I you look at my second picture you see that i need the amount of customers per what 'kind' of change has been made as from witch subscription to witch.
I now are looking into duplicating my data source and union them to open up other possible solutions to my problem. Maybe that will work...
