If i block an account using RAC I have the problem that the Splasher no longer works on its parents. Is there any workaround for this?
theres no direct fix to this. Its kind of working as designed (as I understand). the OLAP engine doesnt think you have rights to the parent because there are no children.
depends on your implementation of RAC to determine the best case work around. Is this a limited user set or do you have a lot of users and permissions that you are managing? Perhaps programmatically loading?
The problem occurs when only some of the children are blocked.
it may sound strange but as a test, grant write access to the parent. i wonder if that will help. hard to say without seeing your exact implementation but it sounds like the denial of permissions on the child is affecting the parent. Since security is additive, allowing write on that parent could theoretically resolve the issue.
I realize thats not a great solution but at least it would help narrow down what the issue actually is.
Have you opened a support ticket yet? might be good to be preemptive about that.
