## Circular Dependency Error

Hi Guys,

I am a self-taught power bi user so I kind of still have problems when it comes to creating measures and columns.

I attempted to create a calculated column which shows me vs Previous Month data for our product's SoM and I used the following equation:

Column = Sheet1[SoM2] - CALCULATE(SUM(Sheet1[SoM2]), PREVIOUSMONTH(Sheet1[MONTH].[Date]))

However, I keep getting this error

Hi @Anonymous ,

You could try to use below calculated column to see whether it work or not.

``SoM2 = CALCULATE(SUM(Sheet1[Sales]),FILTER(Sheet1, YEAR(Sheet1[MONTH])*100+MONTH(Sheet1[MONTH])= YEAR(EARLIER(Sheet1[MONTH]))*100+MONTH(EARLIER(Sheet1[MONTH]))-1))``

I use sheet2 in your sample as dataset. You could refer to my sample for details.

Hi @dax

I attached the link for the data sample as per your request.

Within the dashboard I created a calculated column for the SoM:

SoM2 = Sheet1[Sales (mio)]/CALCULATE(SUM(Sheet1[Mio Sales]),FILTER(Sheet1,Sheet1[MONTH]=EARLIER(Sheet1[MONTH])))

and now I am looking to get a vs Previous month between jan and feb, however, as already stated I keep getting the circular dependency error.

Thanks!

@Anonymous , This seems strange. But anyways, you should prefer to create a date table and join that with you date and use that in previous month

Like

Column = Sheet1[SoM2] - CALCULATE(SUM(Sheet1[SoM2]), PREVIOUSMONTH(Date[Date]))

Also in time intelligence do not .Date , Have a date table in case you have time stamp

Column = Sheet1[SoM2] - CALCULATE(SUM(Sheet1[SoM2]), PREVIOUSMONTH(Sheet1[MONTH])) // Not [Date] it is .Date
New Date = [Month].date

Column = Sheet1[SoM2] - CALCULATE(SUM(Sheet1[SoM2]), PREVIOUSMONTH(Sheet1[New Date]))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :
