_PREV M 9l =
CALCULATE(SUM('STOCKS ES FERT'[9L]);
PREVIOUSMONTH('FiscalCalendar II'[Date]))

 

_STOCK 9L = SUMX('STOCKS ES FERT';
'STOCKS ES FERT'[9L])


_% PREV M 9l =
IF(SUM('STOCKS ES FERT'[9L])>0;
DIVIDE(SUMX('STOCKS ES FERT';[_STOCK 9L]);
CALCULATE(SUM('STOCKS ES FERT'[9L]);
PREVIOUSMONTH('FiscalCalendar II'[Date])))-1)

@rdiazd73 ,

Try like

DIVIDE(([_STOCK 9L]-[_PREV M 9l]);[_PREV M 9l])

Previous Month is 0, so % increase is infinity 2/0

Hi
thanks for your help
your formula partially fixes the error, ok the erroneous percentage disappears,

but it should propose a growth percentage stock previous month 0 current stock 2 percentage increase + 200%, no ?

thanks

Right, because it is dividing by zero,but it looks like you are using the third parameter of the DIVIDE function to account for this kind of error, right? Maybe just try 0 in that third parameter?
