I want to get number of months user selected using Relative Dates Filter?
If user entered "Last 3 Months" then I wants to get number of days for 3 months to use these days in another calculated field.
Calculated field which is using this is as follows.
([Total Sale within Entered Date]/[Number of Days])*365
which returns me predicted sales for the whole year.
Here, [Number of Days] is the filter which I am using. Picture added for Relative Dates filter I am using.
Screenshot of Relative Date Filter:
You need to create a calculated field that works out the number of days in the data.
Something like datediff('day',min([dates]),max([dates])) if data is present for all the days in the time period will work. This calculation will dynamically give you the number of days between the first and last date in the [dates] field for whatever data is selected by the filter (so won't be precise if not all the possible dates are represented in the dataset).

]Difference and percent Difference must be calculated.
I cannot do Apr20-MAy20 because it is not always the same. I need to show the current month and previous month
So I did a relative filter to just show the current month and previous month.
So the difference of two columns should automatically change when the month changes.
Now how do I get the same month of prior year, how do I filter ?
I also need to calculate the difference of current year same month and previous year same month.
Thank you in advance for any help!
When I do table across difference, the difference value is overwriting the existing May and Apr month values as the below screen shot, how to show the difference in another column
Currently:
Below is Expected:
Sounds like you should create a custom filter for the dates. You want:
This month this year
This month last year
Last month this year
There are a number of ways you could do this. I'll give one example and will assume there aren't any future dates in your data set.
[DateFilter]: DATETRUNC('month',[YourDateField])>=DATETRUNC('month',DATEADD('month',-1,TODAY())) OR DATETRUNC('month',[YourDateField])=DATETRUNC('month',DATEADD('year',-1,TODAY()))
Put the to the filters shelf, set to True, and it should keep the months you want.
Then you can just use the standard table calculations to calculate Difference and Percent Difference.
Note, the formula isn't tested, just typed directly into here, let me know if it doesn't work
Based on your comments look at creating separate calculations for to YoY / MoM / etc calculation. That also means creating calculated fields to isolate the Current Month, Previous Month, etc.
For example, the current month:
[isCM]: DATETRUNC('month',[YourDateField]) = DATETRUNC('month',TODAY())
The previous month:
[isPM]: DATETRUNC('month',[YourDateField]) = DATETRUNC('month',DATEADD('month',-1,TODAY()))
Then month on month, something like:
[MoM]: (SUM([Measure])*INT([isCM]))/(SUM([Measure])*INT([isPM]))

I have a date column which I am trying to query to return only the largest date per month.
What I currently have, albeit very simple, returns 99% of what I am looking for. For example, If I list the column in ascending order the first entry is 2016-10-17 and ranges up to 2017-10-06.
A point to note is that the last day of every month may not be present in the data, so I'm really just looking to pull back whatever is the "largest" date present for any existing month.
The query I'm running at the moment looks like
SELECT MAX(date_col)
FROM schema_name.table_name
WHERE <condition1>
AND <condition2>
GROUP BY EXTRACT (MONTH FROM date_col)
ORDER BY max;
This does actually return most of what I'm looking for - what I'm actually getting back is
"2016-11-30"
"2016-12-30"
"2017-01-31"
"2017-02-28"
"2017-03-31"
"2017-04-28"
"2017-05-31"
"2017-06-30"
"2017-07-31"
"2017-08-31"
"2017-09-29"
"2017-10-06"
which are indeed the maximal values present for every month in the column. However, the result set doesn't seem to include the maximum date value from October 2016 (The first months worth of data in the column). There are multiple values in the column for that month, ranging up to 2016-10-31.
If anyone could point out why the max value for this month isn't being returned, I'd much appreciate it.
You are grouping by month (1 to 12) rather than by month and year. Since 2017-10-06 is greater than any day in October 2016, that's what you get for the "October" group.
You should
GROUP BY date_trunc('month', date_col)
My sheet has measure names divided by ops managers and managers filtered to show values only for current week. What I need is to make new column for each of the measures to show values for previous week and then make %diff. I have seen solutions by putting week in row but is it possible this way somehow?
What I tried:
LOOKUP(sum([missed hours]),-1) (shows values from previous row)
{ FIXED DATEPART('week',[metric_date]),[ops_login_name],[supervisor_login_name]:sum([missed hours])} does nothing, same values as normal
I even tried separate calc field DATEPART('week',[metric_date])-1 that shows previous week number and then { FIXED [previous_week],[ops_login_name],[supervisor_login_name]:sum([missed hours])}
You can do this by filtering for the desired week in the Measure Value and not in the filter shelf. Create two boolean expressions that isolate your week.
Is this week? : datetrunc('week',{max([metric_date])}) = datetrunc('week',([metric_date]))
Is last week? : dateadd('week',-1,datetrunc('week',{max([metric_date])})) = datetrunc('week',([metric_date]))
Then create week specific measure values with sum(if [Is this week?] then [total_miss_cnt] end)
Repeat for previous week and then you can do a % diff. Make sure to remove and date filtering from the filter shelf.
In one worksheet, to display the measure value (Sales) of Last 12 Months(LTM) and Previous 12 Months(PTM) from the selected month.
Current Month is 2018-June , By default selection
PTM date range for the sales period as (2016-June to 2017-May)
LTM date range for the sales period as (2017-June to 2018-May)
If user selects different month from the drop down, let's select (Apr 2018)
PTM date range as (2016-Apr to 2017-Mar)
LTM date range as (2017-Apr to 2018-Mar)
This can be done using a parameter. Here are the steps involved:
Create a date parameter
Create a calculated field as below(You might need to fine tune it to match your exact requirements)
Add the calculated field to filter card to show only 'SHOW'
Could someone please explain me creating BINS based on Weekdays in Tableau? I tried creating different Calculation Fields but it won't work
You're working too hard.
Tableau already knows how to bin values by dates at many levels of granualarity: such as year, month, day, weekday, hour etc. So you don't need to create a new field to bin dates by the day of the week. (creating bins is not difficult, it's just already available in this case)
Just put a discrete (blue) date or datetime field on a shelf. You'll see the date level of granularity displayed like, say, YEAR(MyDateField) with a leading plus sign.
You can either
click on the plus sign to drill down by adding a second level, say MONTH(MyDateField)
or
right click on the field to select the date level of granularity you want
Alex's Answer is exactly correct, Tableau will perform the operation automatically. What is great about is that you can select various formats (Full day name, number, 1 letter or 3 letter day etc.).
However if you absolutely need to you can used this formula:
datepart('weekday',[Date])
to give you the 1 (Sunday) to 7 (Saturday) value if you need it for something other reason, say another calculation.
