[SOLVED] ROWNUMBER() in RapidMiner

Hello,

currently I m trying to get my whole ETL for a process in Rapidminer. I ve got a table (A & B) like:

colA | colB | colC
A    | 2      | 1
A    | 4      | 2
B    | 1      | 1
C    | 2      | 1
C    | 3      | 2

Is there a way to create column C in rapidminer? In MS SQL I can use Row_Number and Partition (http://msdn.microsoft.com/de-de/library/ms186734.aspx) . I found a way using Loop Values, but this is far too slow for a table with several 10ks of examples.

Regards,

Mario
