Previous Year Performance

[heygowtam]

I have a Table with three Columns 
[Sales],[Date],[Category]

I am looking for a DAX which shows me the Percentage of Sales (Call and Usage ) Category against the Total Sales of all Categories,  for the Current year and the Previous Year
Curren year starts July 2022 - July 2023
Previous YEar  = July 2021 - July 2022

I am using Card Visual, I need to show the difference between the previous year and the current year (In Percentage)

@heygowtam , With help from date table joined with date of your table

Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-1,Year))
Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),SAMEPERIODLASTYEAR('Date'[Date]))

YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD('Date'[Date],"6/30"))
Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-1,Year),"6/30"))
