If you are following Tableau new features, you might observe that there is a new feature in parameter to default a value whenever workbook opened (available 2020.1 onwards). By using this feature, we can default today’s date parameter calendar. Parameter selection shows current date when ever workbook is opened freshly.
Let us follow the steps:
Step 1:
Create a date parameter
to pick date from calendar.
This will show calendar
view to pick date
In above it is showing date
selection as 11/24/2020. So, every time whenever it is opened it will be
defaulted to same date.
If you observe in below
image you will see one new option “Value when workbook opens”. It is defaulted to
“Current Value” then workbook always opens with same value.
If we assign dynamic
value to this then workbook will open with dynamic value. For this scenario we
want to open workbook with current date every day.
Let us create calculation
for dynamic date.
Step 2:
Step 3:
Assign this “Today” field
in Date Parameter. Edit Date Parameter and Change “Value when workbook opens”
to “Today” (you can select Today calc field in drop down list)
Now this parameter will
show current date dynamically on every day.
