Portal Inbox workflow item display differently. Anyone can help?

Dear All,

I have a problem with my portal inbox. My workflow item in my development portal inbox is displaying differently from the production environment.

For example when the MSS user click on leave approval item in his inbox to approve a leave, my development portal is displaying the approval screen in a better view but the production is just displaying the backend sap inbox screen.

Anyone knows where I can configure this and is there any documentation for it. I suppose this is a UWL configuration right?

Thanks,

Regards,

Bryan
