## How do I insert month into my PY sales formula so it shows PY sales by month on the chart?

Dear All,

I really need your help.

I need to calculate Sales for current year (POS CY), for last year and two years ago (my dates are not continuous, thus I can’t use DATESADD etc).
Those are my formulas:
POS CY =

CALCULATE (

Sales[POS],

FILTER (Sales, YEAR ( 'Sales'[Week_Ending] ) = MAX ( 'Sales'[Year] ) )

)

POS CY =

CALCULATE (

Sales[POS],

FILTER (Sales, YEAR ( 'Sales'[Week_Ending] ) = MAX ( 'Sales'[Year] ) )

)

POS 2YRS AGO Alternative =

CALCULATE (

Sales[POS],

FILTER (

'Sales',

YEAR ( 'Sales'[Week_Ending] )

= MAX ( 'Sales'[Year] ) - 2

)

)

So, the results are fine when I use the table visual, however I run into problem when I try to display sales on a clustered column chart. The sales for Jan and Feb show the corrects results for three years, whereas the sales for March 2019 to Dec 2019 – are wrong – the 2018 sales shift to 2019 sales and 2017 sales (2 Yr Ago sales) are shown as last year sales.

To prove my point, I hardcoded the sales by year and have two charts - the top has the dynamic formulas that shift starting in March and the bottom chart shows the right results

Hi @a96klzz,

By my test based on your description, you could create a calendar table with CALENDARAUTO().

Then you could modify your formula like below.

```CY =
CALCULATE (
SUM ( Sales[Value] ),
FILTER (
'Sales',
YEAR ( 'Sales'[Date] ) = YEAR ( MAX ( 'Sales'[Date] ) )
&& MONTH ( 'Sales'[Date] ) = MONTH ( MAX ( 'Table'[Date] ) )
)
)

PY =
CALCULATE (
SUM ( Sales[Value] ),
FILTER (
'Sales',
YEAR ( 'Sales'[Date] )
= YEAR ( MAX ( 'Sales'[Date] ) ) - 1
&& MONTH ( 'Sales'[Date] ) = MONTH ( MAX ( 'Table'[Date] ) )
)
)

L2Y =
CALCULATE (
SUM ( Sales[Value] ),
FILTER (
'Sales',
YEAR ( 'Sales'[Date] )
= YEAR ( MAX ( 'Sales'[Date] ) ) - 2
&& MONTH ( 'Sales'[Date] ) = MONTH ( MAX ( 'Table'[Date] ) )
)
)
```

Then you could create the chart like below. More detaild, please refer to the attachment.

## Re: How do I insert month into my PY sales formula so it shows PY sales by month on the chart?

Dear Cherry,

thank you for your input.

I have a calendar table in my power bi report that has data till 2019-12-31 so when I tried creating an auto calendar it got all the dates till the end of Dec.

I tried then pulling the sales calendar (as it has dates till February) but now I have two calendar tables and I am worried about connecting my Sales table to a newly created POS Calendar as I don't know how to overcome the issue of POS table connecting to two Calendar tables (or picking between them).

Is there a way to calculate POS PY without creating a new table?
Could I somehow specify in my POS PY calculation that I need to pull the latest month from the latest year

POS PY= CALCULATE(Sales[POS],FILTER('Sales',YEAR('Sales'[Week_Ending])=MAX('Sales'[Year])-1) &&... the latest month from the latest year )

I tried writing [original formula] && Sales[Row Number] = MAX(Sales[Row Number] ))) but then my POS PY calculation would disappear.

I don't know why and I have no idea how to fix my calculation  Community Support Team

Hi @a96klzz,

If you have had a calendar table, you don't need to create a new one with CALENDARAUTO().

You could see from my attachment, my calendar table also have date till 2019-12-31.

Please note that I did not create the relationship between the calendar table and the Sales table in my attachment.
