Reports keep on evolving. Users keep demanding new addition to views or
information to existing reports. Now when you add new columns to an existing
report, by default it ends up in all your existing views. You have to manually
edit each view to restore it to how it was earlier. It is really annoying when
you have multiple views in multiple reports to modify.
To work smart in this situation, before adding any
column to the existing report, open your existing report in Edit mode and click
on Analysis properties.
Go to data tab and for Display of Columns Added in
Criteria Tab select Exclude from existing views, but display in new views.
Click OK and save your report.
After this property is set, your existing views will
remain unchanged as the new column added will be in the Excluded section of the
view.
Hope it helps.
Cheers!
