Missing Aggregator stage properties

[PeterPol]

Hello,

I have a parallel job that includes an aggregator stage. Because performance is not sufficient I want to see if a server job will make sense. However, when I look in the aggregator stage of the server job, there seems to be no properties that allows me to set grouping keys, aggregation column properties, and other options.
My server aggregator stage has 3 tabs (stage, inputs, outputs). The stage tab has only one general tab in which I can set stage type, description, before- and after stage subroutines, and input/output values ??

Somebody knows what I do wrong?

Peter

In the server Aggregator stage it's all done through the Derivation in the Columns grid. Double click in this cell to open the derivation editor, then select the input column then either check the Grouping check box or choose an aggregate function from the drop-down list.
