This is absolutely elementary requirement. And should not be a complex one for Oracle to develop, implement. Please do at the earliest. We have users refusing to adapt to M, B and as IT team for us to keep modifying so many numbers, metrics across workbooks to introduce Lakhs (100000) or Crores is painful

Looking for the same capability. We have implemented custom roles, security rules to restrict users by BU. But this doesn't work for custom reports.
