CATS Classic Scenario

Hi Gurus,

Need your input on a task which is - The secretary logging the manager's time sheet.

I am not sure how to proceed. I could think of using Transaction iViews to bring the CATS Classic application to Portal. But we are in the middle of the ESS integration into Portal and the client wants the look and feel of this application to be like that of CATS Regular iViews that come with ESS/ WebDynpo.

How can this be achieved? What are the places where customization would be required?

Greatly appreciate your inputs.

Thanks in advance.
