Web Dynpro ABAP Process Configuration for Appraisals

Hi,

I wish to utlize the feature of process/phase/step configuration for appraisals by the Web Dynpro configuration for tab and process. I choose the "Process Configuration" tab, enter my appraisal template and period, and click "Start Selection". A warning is displayed "No process defined for <my appraisal template>". Clicking on "Add" and no matter what I did, I don't seem to be able to maintain any process/phase/step into the "Configure Available Elements for Process" table. What is the pre-requisite to maintain and configure the Process/Phase/Step(s) ? Thank you.

Regards

Kir Chern
