Try Delete Root node but edit authorization for sub node needed

Hello,

i try to the delete a BO instance. For that the user need the delete authorization (Activity = 06).

For the root note the check will be executed with activity '06' and for the subnode with activity = '02' (Edit).

But i dont want give the user the "Edit" authoriztion.

How can i switch the check for that use case? Why does BOBF check agains "Edit" and not "Delete"?

It is a "Business Process Object" which have a super object. We redefine something on root node and re-use the sub node.

Kind regards
