Lock EPM Context Member Selection from BPF

Hi all

Our business administrators are complaining that some users have been changing the EPM context in a BPF shortly before launching an EPM report.  This causes the report to build incorrectly and not as the BPF was designed to function.

Is there a way to lock down these BPF context defaults ?  If you take the trouble to setup workflow, I'm surprised that you would be able to manually override what has been set in this way.

Of course, the obvious answer would be "don't touch it" but I'm hoping there is a method out there which is a little more water-tight.

Thanks

Ian
