Im having two field on the object opportunity product.
One field is called ABR, this is a formula field which is "holding" the existing value.
The other field is called ABR (roll-up) that is just a currency field which should mirror the same value from ABR, so I can use this field for sum roll-up (formula fields are some how not showing up to do roll-up).
So best is that I could design a workflow/process, that whenever the oppty that has those products related is changed (change in edit date) ->this should be the trigger, then whatever value is in ABR->should get push aswell into ABR (roll-up).
With that I would achieve that I do not need to manually go into every added product line item to do the changes, I could just mass run updating oppty and have the trigger.
Many thanks for your help,
Philipp
