I'm scratching my head about a PI analysis backfill issue. A user is mapped to Administrators on an AF server and the database, but cannot backfill analyses. They get the error "Recalculation error: Cannot write data for Attribute 'whatever' in Element 'whatever' because the current user does not have WriteData permission."
I can do the same backfill and I have exactly the same permissions on the AF server - as far as I can see, anyway.
If I give Write Data permission to "World" for the element, the user can backfill successfully, so it is definitely an AF permissions issue. Administrators already has Write Data permission.
Any ideas on what to check?
