sum of data up to a given day

[Luke_Killer_IT]

Hello,

I have a problem I would like to sum up the data to the current day and the data are displayed every week. I tried to use such a script:Sum({$<PP_Auftrag.BelegNummer={"*"}, V_BelegPos.Versandtermin={"V_BelegPos.Versandtermin=Today()"}>}[V_BelegPos.xPlanzeitATP]*[V_BelegPos.Menge])

Would you be able to help me?
