Exclude assignment block relationships from ACE

Dear All,

as we have to restrict access to accounts by complex sales structures and the only available authorisation object left in the PFCG for accounts is B_BUPA_GRP (besides BADi's of course) we need to use the ACE.

For example: A sales rep should see all accounts with role customer, for which he has the relationship responsible employee. For this we set up an ACE right.

He also should see and open all contact persons for the respective customers. Thats a second ACE right.

The sales rep should also get displayed the name of other accounts in other roles in the account assignment block relations. But with this ACE rights he just gets the contact persons.

If I allow access to the other roles he can open the accounts with information, he should not see.

Thus we just would like to display the basic data in the relation assigment block.

Is there a way to exclude the ACE function from specific views in the UI?

Thanks

Andreas
