@Anonymous Please try below measure to add 10 % of previous sales to current sales. I'm assuming you are identifying the previous sales based on date. If it does work please share sample data

Expected = 
VAR _prevdate = CALCULATE(MAX('Table'[Date]),FILTER(ALL('Table'[Date]),'Table'[Date]<MAX('Table'[Date])))
VAR _prevsales = CALCULATE(SUM('Table'[Sales]),'Table'[Date]=_prevdate)*0.10
RETURN CALCULATE(SUM('Table'[Sales]))+_prevsales
