Q) How does Reapply help?
Or, when could I use Reapply?
A) e.g. Please refer following screenshot:
You are Analysing a Dataset.
You have applied Filter on Date Column, to focus on April month entries.
You realize the highlighted entry (in above screenshot) is incorrectly added in April month, and should instead be in May month.
You change April to May.
To remove May month entry, and to refocus only on April month entries, You can use Reapply.
Data tab > Sort & Filter group > Reapply.
Just click on Reapply - May month entry will be filtered out, and only April month entries will be visible.
Note: Reapply is only applicable when You make changes to Column(s) on which You have applied Filter.
e.g. in the above example, You applied Filter in Date column. If You make any changes in Region column, and click on Reapply, nothing will happen.
