Popup window to enter Rejection reason- TRIP APPR Workflow

Hi All,

We have a requirement for Travel-Trip workflow template - WS20000040.

We are on ECC 6.0 EP 7.0.

When a Manager clicks on Rejection button or Send back for corrections,

they would like to see a popup window, where they can enter the reason

text and send it to Employee. As I recollect, we were able to achieve

this using ITS.

Currently, STD Workflow creates a new workitem in UWL for the manager

to open the task where he can enter the reason and send it across. But

we need a solution with popup window.

Is it possible to trigger a popup window for the rejection reason and

capture the reason to send it across to Employee??.

Please let me know if need more details.

Thanks in Advance !!.

Thanks

Aravind
