Add rows / missing date values

Hi all.   Recently I found out that my dataset from SQL server lacks some information. My dataset is about machine units and their daily performance. However, if a unit did not work some particular...

Hi karimkz.

 

In your scenario, you can follow below steps to achieve your requirement:

 

1. Duplicate this query connect to the SQL Server database, filter the original query only keep cat data, rename it as cat table. Also filter the duplicated table to only keep hitachi data, rename it as hitachi table.

2. Create a calendar table.

3. Merge the calendar table with cat table and hitachi table separately. For the unit column, use Fill down or up, for the value column, use Replaces values as 0.

4. Append the cat table with hitachi table.

 

For more information, please check attached .pbix file.

Thank you for your answer! 

 

I see your point, I believe it will work out. Gotta learn how to do all that things though. 

 

Also I think of creating a date table, then do something like:

CALCULATE(SUM(performance); FILTER(date; date.month=EARLIEST(month))).

 

Do you think it will work?

      Creating a calendar table and merging it with the existing table is still a best option.

        You need to dimensionalise your data.  I would create a separte date table and a seperate unit table (with the distinct list of unit types).  You can then use a calculations like this:

         

         

        CALCULATE
(	
	AVERAGEX
	(
		CROSSJOIN
		(
			VALUES('Unit'[Unit]),
			VALUES('Date'[Date])
		)
		,SUM([Performance])
	)
)

         

        CROSSJOIN will give you the product of all dates and all units that are currently being filtered.  Then AVERAGEX will iterate over this calculating the SUM and then finally calculating the average.
