Hi Praveen,
Not yet, we have an incident opened with SAP. As a workaround, if we have to lock context dimensions in a report, we lock them with such members selected that users have access to (in data access profile). Then it will not unlock. In this case, we have to check user set for a particular report and their data access rights.
I am now thinking what if we hide these dimensions in context options. Anyway we are not letting users change them. I haven't tried it though.
Let me know if you find a solution to this issue.
Regards,
Neha
