Convert minutes into days and timeformat

Hi - thanks, it works. Hopefully the VAR function works quick enough also with big data!

I have modified your DAX, to display the days or not, and hour work day has only 15 hours, so I divide through 900 instead of 1440.

WE Dauer gesamt =
var Tag=  INT(Lagerbeleg[WE Dauer in Min] / 900)
var Stunde=  INT(MOD(Lagerbeleg[WE Dauer in Min]; 900) / 60)
var Minute=  MOD(MOD(Lagerbeleg[WE Dauer in Min]; 900); 60)
var Sekunde= INT((Lagerbeleg[WE Dauer in Min] - INT(Lagerbeleg[WE Dauer in Min])) * 60)
return
IF(Tag = 0; "";
  IF (Tag > 1; Tag & " Tage "; Tag & " Tag "))
& FORMAT(Stunde; "#00")
& ":"
& FORMAT(MINUTE; "#00")
&":"&
FORMAT(Sekunde; "#00")
