Date Hierarchy from calculated column - how? - powerbi

I have a dashboard to convert - source needs to change from custom, local Excel file to a dataset and SQL Server table via DirectQuery. Excel file was created by exporting data from said dataset, which have been worked over.
Now, the problem is that I don't have date column available, all I can do is convert date_key (int) column into date, and I need a hierarchy to drill down in visuals from years to days.
This is what I have in table based off Excel:
This is what I have in table that I need to use:
Definition of Date:
Date = FORMAT(Date(Left('A'[date_key],4),Right(left('A'[date_key],6),2),right('A'[date_key],2)), "dd/mmmm/yyyy", "en-GB" )
I can create additional columns to add to the hierarchy:
...and it sort of works, but visual is awful to read when drilling down:
instead of
and of course converting month to name (January instead of 1) reorders them alpabetically...
Is there something to be done here, please?

Power BI visualization of data with a Start and End date

THis is an example of what I think i need to do
I would like to ask some modeling advise I cannot solve myself:
I am using Power BI to visualize the time machinery is out of order.
The source is a register of equipment not functioning, with a start date and end date (note that there is no end date if the machine is not fixed yet).
I would like to show the time (hours, percentage, etc) that the machinery is out of order, filter for a specific period /date (e.g. month).
So I have 2 date columns: ‘’Start out of order’’ and ‘’Back in order’’
I do have a date table, which I usually would connect to all the date variables. However, since I am working with a Start and End date. This does not give the result I am looking for.
Any help is very much appreciated!
Kind regards,
Link to my Power BI FILE:

I am not sure how you would like to visualise your data, but this is what I managed to do:
create a daysdiff column with
Daysbetween = IF(ISBLANK(TF_Eventos
[End out of order]);DATEDIFF(TF_Eventos[Start out of
order];TF_Eventos[TODAY];HOUR);DATEDIFF(TF_Eventos
[Start out of order];TF_Eventos[End out of order];HOUR))
This creates your column to check difference between Dates.
Then create a separate column with your Date. In this case I copied the Start out of order date, since I thought you might wanted to be able to filter for the start dates. Then simply create a relationship between your newly created Date column and your start out of order date.
Doing so lets you create a visual with the daysbetween (in this case portrayed in hours) and your start dates. Now just simply add a slicer and you can filter on date.
Hope this helps

Change column values based on slicer selection

Using PowerBI desktop, I have created a small table (called TimeSelector), with three elements: Day, Week and Month
The idea is to use the content of this table to create a slicer with three options
Thus, selecting one of those options should change the way dates are used in tables.
For instance, selecting Day would result in the following table:
While selecting Week would result in this:
Etc..
I have tried to write a new measure taking in account the selected slicer element, but it is not working:
DayWeekMonthSelection = IF(CONTAINS(TimeSelector;TimeSelector[DayWeekMonth];"Month");
MONTH(VALUES('uptime_downtime'[Uptime_date])))
This is only the first part of the formula, only testing the month option as a start.
Any idea on how to do this?
To offer another perspective:
The approach I take with this is to have a separate table in the database - containing meta data about the date, called date_lookup.
2 of the fields in this table are FirstDateOfMonth & FirstDateOfWeek.
Some of the other fields are lastDateOfMonth & LastDateOfWeek, also DayOfWeek.
By using these fields I can easily present visuals that are grouped by month or week.
Sure you can use functions to get this information, but functions can be platform dependant. If you're making a join to the date_lookup anyway - it's no more effort to get this info from there...
The main reason we need to store this meta data is our company Financial year is Jul - Jun. Therefore we need to have available the Correct FY - which is stored as a field in the date_lookup table. I also have fields in there identifying public holidays...
This is an interesting question, but I'm not sure how to do exactly what you are asking for, so I'll suggest an alternative. (Changing a measure based on a slicer selection isn't too difficult, but I'm not sure a good way to swap out a field/dimension.)
Instead of creating a separate table for your slicers, a different possible approach would be to create a date hierarchy. Often when you drag a date column into the rows or columns box it will automatically create a date hierarchy with Year/Quarter/Month/Date, but since you want week and not quarter, let's create one manually.
First, create a couple calculated columns for week and month. For example:
Month = FORMAT(uptime_downtime[Date], "mmm")
Week = WEEKNUM(uptime_downtime[Date])
Now right-click on the date on the fields, and choose New Hierarchy. It should look like this now:
Now drag the Month and Week columns onto Date Hierarchy and then rearrange them in the appropriate order:
Now you can use that hierarchy in a matrix and use the drill up and down buttons
to get the different groupings:

Dynamic column names in power bi

I have imported an excel file for creating a PBI report. In this excel, there is a cell which contains a date. I want to create columns on the basis of this cell.
Like if the cell contains 01/04/2017 then I would like to generate column names like Apr-17, May-17, ..., Dec-17, Jan-18,..., Mar-18.
If there any way to do this?
I'd say just create a step by step procedure in edit query to pivot the table.
First you'd only get distinct values, then pivot and then promote to headers.
I don't think you need a column per month.
1) Create a query to import your file
2) In Query Editor, select the query, then "Transform" -> "Use First Row As Headers"
3) "Transform" -> "Unpivot Columns"
4) Rename columns as desired
Now you have a table in a comparable/filterable/queryable form. You didn't specify what you need it for but having a column per month won't work well (for various reasons). PowerBi doesn't work quite like excel.
If you really wanted a column per month, you could stop at step 2) but I would advise against it.

Creating Date Relationship in Power BI for Slicers

I'd like to slice across visuals based on dates in MS Power BI (i.e., one filter for say month will slice all visuals for that time period.
I created a date table from http://www.agilebi.com.au/power-bi-date-dimension/ to link to the date columns in each table.
I connected xlsx workbook.
Image of columns in Power BI
I added tried to edit the relationship so connect the 2 date columns. However, when I insert the filter using the date_table as values and try to use it, the visuals disappear.
Visuals are Gone
However, when I create the slicer and slice across multiple visuals, they go blank.
**I tried changing the type to "Both" but it didn't fix the problem.
The script at AgileBI.com.au creates a date table with a 'Date' field that has a data type of text. You can (surprisingly) do a relationship between 2 fields of different data types and not get an error. However, a join between a text field that contains dates, and a regular date field will mean that rows that look like they should match up do not.
You can confirm this is happening by picking a value in the 2 tables that you think should match up and seeing if they are identical. In my case, I had Tuesday, November 01, 2016 in my imported table, and 11/1/2016 in the other table. While they both represent the same date (in the US), they clearly look different. A good place to see this is in the Edit Relationship screen (and it definitely would have been helpful to include a screenshot of that in your original post).
Anyway, if the dates in your table don't match up to the corresponding (text) dates in the Date table, then when you filter to "2016" on your slicer, the visuals will all go blank.
I would recommend:
Click Edit Queries
On the left hand side, select the table of dates (called Invoked Function by the script)
Click on the header for the Date column (it will likely already be selected)
Select Transform on the ribbon
Change the Data Type from Any to Date
Click Home > Close & Apply
Hope this helps.

Format date field in Power BI service

I have imported an Excel file to Power BI service from my OneDrive for Business.
The file contains a simple Excel table and one of the fields is a date.
Now, in Power BI service, I get that field displayed as a whole number which isn't very useful to read in a report.
How do I change the field to display as date?
Thanks!
We can use FORMAT() method to format date value, Use below mentioned formula
Syntax: Column = FORMAT(Table[column],"MM/DD/YYYY")
Column = FORMAT(DailyActiveUsers[startDate],"MM/DD/YYYY")
Before my data:
After my data:
This usually works by default for true Excel dates. Anyway, just open the Edit Queries window and navigate to your table. In the column header for your Date, change the Data type to Date. Close & Apply to see the result in your report.
