Divide column based on other two columns

Anonymous — Tue, 07 Jan 2020 18:14:16 GMT

Hi guys,

I have this table below, the only in my model. As you can see, the Volume (CY_B_Vol) only shows in the first week of each month.

I would like then to be split in weeks according to how many weeks we have in a month (if the month has 5 weeks, split (CY_B_Vol) by 20 if the month has 4 weeks split (CY_B_Vol) by 25), like in the yellow column.

It seems like a simple thing to do, but I've been struggling with this for 2 days without a solution. ☹️

Could anybody help me, please?

Thanks!

In Power Query Editor screen, select column CY_B_VOL and click on Fill (Down) in the Transform tab:

Then click Close & Apply and add a calculated column to your table:

CalculatedColumn = VAR _curMonth = Table[Month_of_Year] RETURN DIVIDE(Table[CY_B_Vol], COUNTROWS(FILTER(ALL(Table), Table[Month_of_Year] = _curMonth)))

Let me know if this works 🙂

Kind regards

Hi JarroVGIT, thanks for your quick reply.

It actually didn't work. =/

First, the volume should not fill down, as I want the count to be done with the first value only.

Second, I need to divide the volume that appears in the first week of each month.

If the month is equal to 3,6,9 or 12, I would divide by 20, the others I would divide by 25.

Anyhow, I appreciate your help 😃

Does your current model look like the table you gave us but without the yellow column? Or did I understand your question wrong? I assumed you have the white columns and you wanted the yellow column. Or are you missing the weeknumbers as well?

Hi JarroVGIT , tks again 😃

Does your current model look like the table you gave us but without the yellow column? Correct! The yellow column is exactly what I want.
Or did I understand your question wrong? I assumed you have the white columns and you wanted the yellow column. Correct again
Or are you missing the weeknumbers as well? No, I'm not.

As you can notice, I'm a newbie. I don't know if my logic is good, but I thought maybe get the minimum value for the week (where the month is equal the selected one and divide (with if based on the month as well); however, I'm still trying to accomplish this.

I really appreciate your patience and attention 😃

Alright then my initial response gets you that yellow column. If you want the columns to be in there original state, please create a copy of column CY_B_Vol before using the Fill option in the Powerquery editor.

Hi JarroVGIT , unfortunately not. =/

Below is what I get in my file doing exactly what you said.

Can you share your pbix file by sharing a Dropbox/Google drive/OneDrive link? Your results are not in line with documented power bi behavior so the error must be somewhere else.

Hi , Try below

Firstly create a calculated column with below dax for filling all the rows Column 2 = var cur='Table'[monthofyear] return if('Table'[monthofyear]=cur,(calculate(sum('Table'[cy-b-col]),filter('Table','Table'[monthofyear]=cur))))

Second Create an calculated TABLE with below dax and create a relationship between main table and this table with [monthofyear] Output = SUMMARIZE ( 'Table','Table'[monthofyear], "Count value", COUNT ( 'Table'[monthofyear] ) )

Now final create a calculated column as below CalculatedColumn = DIVIDE('Table'[Column 2],if(RELATED(Output[Count value])=5,20,25))

..Its a bit lengthy but will serve your purpose...
