I have a backup report which has ‘data centre’ and ‘offsite’ components. Failures due to tapes not being loaded ‘offsite’ are exempt from SLA, where as those at data centre are inluded in SLA.

Problem is that operators can ‘copy and paste’ the ‘exempt’ code even if the selection is not available from conditional input…..

I’ve used this approach and it does seem to work. I don’t see other users using this feature often and for the casual user at least it does not appear to be obvious.

Given the problems with errors in spreadsheets I would prefer it if Microsoft made this feature both more obvious and user friendly It would be helpful if you could toggle the sheet to clearly identify the protected cells. These could be highlighted by shading or something similar.

Good luck with your blog!
