[make]

FOR EACH mytable BREAK BY mytable.artikel_nr :
Hi there !!!

i use the following code for some calcs.
Now my problem :

in the mytable i have a field called datum ("date !"). I have to use the break group for different days, because the field artikel_nr can be the same on different days.
Can anyone help me ??
ACCUMULATE mytable.stueck(SUB-TOTAL BY mytable.artikel_nr).
IF LAST-OF(mytable.artikel_nr) THEN DO:
CREATE result.
ASSIGN result.artikel_nr = mytable.artikel_nr
result.stueck = (ACCUM SUB-TOTAL BY mytable.artikel_nr mytable.stueck).
result.Lieferant = mytable.lieferant.
result.Datum = mytable.datum.
result.AuftrNr = mytable.auftrNr.
result.Glas = mytable.glas.
result.Durchm = mytable.durchm.
result.Et = mytable.et.
result.Farbe = mytable.farbe.
result.Sphaere = mytable.sphaere.
result.Zyl = mytable.zyl.
result.Addition = mytable.addition.
result.Richtung = mytable.Richtung.
END.
END.
