I have a question on Power BI, basically i have a column with date (HIREDATE), and my task is to add a column that calculate the difference between the ACTUAL date and the date on my column. So it needs to be dynamic.
I watched some youtube videos but haven't found a case like mine, even though i think it's a common, not very rare task.
Following a tutorial on Youtube and on Microsoft WebSite I added a custom column named Experience with the following code :
= Duration.ToRecord ( YEAR(TODAY()) - [#"Date d'embauche"]) /* Date d'embauche = HIREDATE in french*/
It shows me :
No syntax errors have detected
But when I click on
OK
It shows me this :
Expression.Error: The name 'YEAR' wasn't recognized. Make sure it's spelled correctly.
Please help me solve this.
For Power Query you would need DateTime.FixedLocalNow() to get the date time, then wrap that function with Date.Year to extract the year, so you would have the following:
Date.Year(DateTime.FixedLocalNow()) - Date.Year([#"Date d'embauche"])
in this example, the formula is used in a custom column, to give the time difference in years.
Normally it is best to do these sort of transformations in Power Query before getting to the data model.
Probably you are adding the Custom column in Power Query. I would rather recommend to add a Calculated Column through the following DAX expression:
Date difference =
YEAR (
TODAY ()
)
- YEAR ( 'Table Name'[HIREDATE] )

How do I populate the number of purchases and sales per day in tableau?
Here is my Sample Data:
In my first attempt, sales numbers are not counted to the exact date.
In my second attempt, I tried to tabulate by dropping sales date into the rows. However, it returned two figures - purchases and sales.
I have also tried Calculated Field but Tableau is unable to do a "for loop" like python.
First attempt:
After dropping Sales Date into the Rows. This is what I get:
Is there any way to populate it like this? Please help, I am still new to tableau. Special thanks to Fabio Fantoni for the first solution!
Desired Format:
I have another sample data (refer to sample data 2) which I would like to populate in the desired format (refer to desired format 2). In Sample Data 2, the purchase date "15/12/2020" is not reflected in sold dates.
My apologies but I may require some guidance as I am still new to tableau. Thank you in advance.
Sample Data 2:
Desired Format 2:
Based on this sample:
In order to bypass your double count for two different date columns, you may want to cross join your original data with a copy of it on original.Purchase = support.Sold, like this:
Doing so, you just have to create two calculated fields:
count Purchase:
count([Purchase Date])
count Sold:
Count([Purchase Date (Foglio11)])
The only thing you have to pay attention to is that in the second calculus you have to count Purchase date due to your "inverted" cross join.
You should get something like this:
Tableau will generally show every single date within table output of the date ranges filtered for. Is there a way to only show the first and last date in the table for the date of ranges selected?
I created an image of the desired output in excel. Link below:
Desired output example
Thank you in advance!
The feature that will address your goal is called a Level of Detail (LOD) calculation. They have many uses and take various forms. I suggest reading about the in the online help.
But, to answer your question, the LOD calc to find the first (i.e. minimum) value in a date field called, say, Transaction Date, is;
{ MIN([Transaction Date]) }
The formula for the latest value is left as an exercise for the reader 😊
As a data analyst, I would like to see the report in a pivot table automatically for the current month, so that I can take a look at it and don't have to change the date filter manually.
This is the formula to show the first day of the current month. (Which is the criteria I need, first of the current month)
=EOMONTH(today(),-1)+1
It works when I put this formula in any cell.
But when I put it in the pivot "filter by condition" option it doesn't work.
This is what I tried.
Text is exactly =EOMONTH(today(),-1)+1 (In formula box)
The date is exactly =EOMONTH(today(),-1)+1 (In formula box)
Here a screenshot of the options
Any help will be greatly appreciated.
I've never had great luck with the pivot table filter criteria in Sheets, I typically filter the data first if it's more advanced or use aggregating functions. In the Sheets pivot tables are better for quick analysis than dashboards.
There's probably a few ways to do it, but one of the easier ways would be to duplicate the data tab, clear the data and use a filter function to retrieve data. Update the Pivot table data source to the new tab. This will always only be the current month's data.
Basically you filter the data before the pivot table, with the [filter function][1].
=Filter(data , [date col]>=EOMONTH(today(),-1)+1 , [date col]< date(year(today()), month(today())+1,1)
You can also add a month column to the data and then filter on that column, however each month you would need to update the month filter in the pivot table.
=date(year([date cell]),Month([date cell]),1)
If you're using it for a 'dashboard' of sorts, I would generally recommend to create it yourself with aggregating formulas (sumifs, countifs, ect) and then you can use the more complex filters.
try custom formula:
=MONTH(A2)=MONTH(TODAY())
where A2 is first cell of column containing valid dates
You can try to Filter by a Custom Formula:
=month(DatePurchase)=month(TODAY())
Where DatePurchase is the Field Name.
I have a "Range of Dates" filter and what I want is for the max (or right most value) to always be the most recent date which should be today's date. What seems to be happening is that if I leave the dashboard open and come back the next day the max value is yesterday's date and I must manually move the slider over to be today's date. How can I accomplish this?
I find a calculated field is the best way to do this as I have run into the same issues using the out of the box max date filter.
Create a calculated field as follows:
[date] = {FIXED: max([date])}
This creates a True False field where only the records that have the max data and carried through.
Now drag this onto the filter pane and select 'TRUE'.
I've generally seen two basic approaches for this problem: Calculated fields and relative dates.
Use a calculated field or parameter or some combination of calculated fields and parameters with filters. This is similar to what smb suggests in their answer to this question. It also seems to be the most popular approach.
If you don't particularly care about being able to set the end-date with the slider, you could try using relative dates, using the approaches detailed in the accepted answer to this Tableau forum question and in this Tableau Knowledge Base article. Jennifer Vonhagel also gives a second answer to the Tableau forum question farther down that uses a parameter plus calculated field approach.
Additionally, this Tableau Knowledge Base article offers another option (Option 1, in the article) if you have Tableau 10.3+: You can use the "Latest Date Preset" (see here for details) check box in the date filter dialog box. I haven't used this, but it looks promising if you're using Tableau Desktop (seems like it wouldn't work for Tableau Web). The article's Options 2-4 are just riffs on calculated fields, in my opinion.
Two more approaches I've heard of – but never personally seen in the wild:
Push the max date down into the view you put Tableau on top of and let the view do the work.
Use a script to modify the Tableau workbook's XML.
I'm trying to convert eight digit yyyymmdd to date format with DAX function.
column = DATE(LEFT(TABLE[COLUMN],4),MID(TABLE[COLUMN],5,2),RIGHT(TABLE[COLUMN],2))
However, I've got an error because of the original column has some records with "00000000", so how can I make a default value with IF statement or are there any better solution?
Best regards
What I typically do is just make 2 distinct Power Query steps and this is handled automatically.
just make the yyyymmdd column a text column
make the text column from step 1 a date column (when prompted, be sure to select 'Add New Step')
replace errors with null
That's it. You can even Ctrl-Click to select multiple columns and combine them into the 1,2, and 3 steps with multiple columns.
