    Hello swikritee_p, thanks for the answer, the cumulative sum works well, BUT it doesnt restarts when the value in the "Applications fongiques" column is "True". For each day we have more then one value in the column "ColuneBotrytis" (one value for each 30 minutes in the day). In the column "Applications fongiques", the "TRUE" or "FALSE" value is repeated in all rows concerning the same date. Maybe this requests a change in the DAX?
