Days difference between when the first items and second item was purchased

Hi,

This calculated column formula works

Column = if(ISBLANK(CALCULATE(MAX(Data[sales_date]),FILTER(Data,Data[partner_key]=EARLIER(Data[partner_key])&&Data[sales_date]<EARLIER(Data[sales_date])))),0,Data[sales_date]-CALCULATE(MAX(Data[sales_date]),FILTER(Data,Data[partner_key]=EARLIER(Data[partner_key])&&Data[sales_date]<EARLIER(Data[sales_date]))))

Hope this helps.

Hi,

I am not sure how you arrived at those number - mine are different.  I just copied the same calculated column formula which i shared with you ealrier and it worked fine.  If you wish to include both days, just add 1

Column = if(ISBLANK(CALCULATE(MAX(Data[sales_date]),FILTER(Data,Data[partner_key]=EARLIER(Data[partner_key])&&Data[sales_date]<EARLIER(Data[sales_date])))),0,Data[sales_date]-CALCULATE(MAX(Data[sales_date]),FILTER(Data,Data[partner_key]=EARLIER(Data[partner_key])&&Data[sales_date]<EARLIER(Data[sales_date])))+1)

Have you even tried my formula?

Ashish_Mathur Thanks for the Dax Expression. We had to create a column in the warehouse to bring in another updated_date, and i used the expression you provided in PBI and tweaked it to include the new column, and it works! Thanks 🙌
