Sales of Closest Date Last Year

[Flpowerbi01]

Hi all, 

I am trying to get the closest sales last year to a date in a row. Please see below of what I want to achieve,

Here are my columns 

Date - On sale Date of a product

Sales - Sales of the product on the on sale date 

Date minus 365 - Date is subtracted by a year

Sales of Closest Date Last Year - This is the column I am trying to get. How do I get the sales of the date that is closest to the "Date minus 365 column". I manually filled out some of the values of the colmun. I cannot use a max or min function for cases when the difference between the two dates is less than 365.

Thank you so much Talespin!

You're welcome.

hi @Flpowerbi01 

Closest Sales before of after Date minus 365?

If Yes, this is a Calculated Column

Closest Sales =

VAR _CurrMinus365Dt = TestTbl6[Date minus 365]

VAR _Cross = CROSSJOIN( ALL(TestTbl6[date], TestTbl6[Sales]), FILTER(ALL(TestTbl6[Date minus 365]), [Date minus 365] = _CurrMinus365Dt))

VAR _Tbl = ADDCOLUMNS(_Cross, "@Difference", ABS(INT([date]-[Date minus 365])))

VAR _MinDiff = MINX( _Tbl, [@Difference])

RETURN  SELECTCOLUMNS( FILTER( _Tbl, [@Difference] = _MinDiff), "NewCol", [Sales])

Hi @talespin , 

thank you so much for this. If there was also a product column in the table. Where will I put an additional filter for the product colum in your Dax code? 

SInce what is happeneing now is that it is getting the closest date even if it is not that specific product? Does that make sense? Or I can give you another example with the product

hi @Flpowerbi01 ,

Please test it.

Added Product to first table in crossjoin.

Closest Sales =

VAR _CurrMinus365Dt = TestTbl6[Date minus 365]

VAR _Product = TestTbl6[Product]

VAR _Cross = CROSSJOIN( FILTER( ALL(TestTbl6[date], TestTbl6[Sales], TestTbl6[Product]), [Product] = _Product ), FILTER(ALL(TestTbl6[Date minus 365]), [Date minus 365] = _CurrMinus365Dt))

VAR _Tbl = ADDCOLUMNS(_Cross, "@Difference", ABS(INT([date]-[Date minus 365])))

VAR _MinDiff = MINX( _Tbl, [@Difference])

RETURN  SELECTCOLUMNS( FILTER( _Tbl, [@Difference] = _MinDiff), "NewCol", [Sales])
