RSUM?

[dmi4587]

Hello all!
I have a small problem with RSUM in Cognos and get always an error with this function.

Here is the following statement:
RSUM(1 FOR DFORDERUNGENGLIEDERUNG.JAHR, DFORDERUNGENGLIEDERUNG.PERIODE, DFORDERUNGENGLIEDERUNG.G1, DFORDERUNGENGLIEDERUNG.G2, DFORDERUNGENGLIEDERUNG.G3 ORDER BY DFORDERUNGENGLIEDERUNG.JAHR ASC, DFORDERUNGENGLIEDERUNG.PERIODE ASC, DFORDERUNGENGLIEDERUNG.G1 ASC, DFORDERUNGENGLIEDERUNG.G2 ASC, DFORDERUNGENGLIEDERUNG.G3 ASC LOCAL) AS SC5

Can anybody tell me, what RSUM does in this statement and why it doesn't work in my Cognos 10 Framework Manager?
Its funny but the function works in an older version of Cognos.

Are there any other opportunities to replace this function with another one?

Thank you in advance!

RSUM is the Cognos 7 expression for running sum. In Cognos 8 and higher the equivalent function would be : running-total
