I don't know if I entitled this post correctly but I haven't got better idea
![Smile :)](./images/smilies/icon_smile.gif)
I have following situation:
colA, colB
1 xxx
1 yyy
1 zzz
2 xxx
2 zzz
3 xxx
and I want to get sth like this
1) xxx,yyy,zzz
2) xxx,zzz
3) xxx
Is it possible to use one of DS stages to do this (maybe transformer) or is the only way, to solve this isue, to use SQL procedure on source database ??
