Calculating Value Changes over Years and months with measures

[Hodgy007]

Ok on this face of it this looks easy buy finding it hard to do using measures, this is v simple in excel, but imagine this is 2 years of data.

Im looking to create a measure for Apples sold this year

and table of apples sold per month (Apples Month Diff)

Date	Apples in Stock
2022-01-03	100
2022-02-01	75
2022-03-01	60
2022-04-01	50
2022-05-02	41
2022-06-01	8

Hi @Hodgy007 ,

Well, please create two columns:

Next month value = CALCULATE(SUM('Table'[Apples in stock]),FILTER('Table','Table'[Month] = EARLIER('Table'[Month])+1))

Month Diff = IF('Table'[Next month value] <> BLANK(), [Next month value] - [Current month value])

The diff value will show from Month 1.

Hi @Hodgy007 ,

I'm a little confused about what's the meaning of  "the first 2 days not being in the date table and it not the end of the year", can you explain it in details ?

If convenient, could you please share with me some screenshots of your data after hiding sensitive information ?

Thanks for your efforts & time in advance.

Best regards,

Hi @Hodgy007 ,

This is my test table:

Please create new columns as below:

Month = MONTH('Table'[Date])

Current month value = CALCULATE(SUM('Table'[Apples in stock]),FILTER('Table','Table'[Month] = EARLIER('Table'[Month])))

Last month value = CALCULATE(SUM('Table'[Apples in stock]),FILTER('Table','Table'[Month] = EARLIER('Table'[Month])-1))

Month Diff = IF('Table'[Last month value] <> BLANK(), [Current month value]-[Last month value])

Create a table visual, is this the result you want?

The diff value of apples sold is in month 2 not month 1 so the charting is out by a month if you try and graph it so it looks like 227 were sold in feb not jan

Thanks, I was able to get this also using a measure not a column but how now would you calculate apples sold in the year to date? As due to the first 2 days not being in the date table and it not the end of the year. So startofyear and endofear date functions don't seem to work
