Help needed with this scenario

[vijay srikanth]

Hi,

This is a scenario to be implemented using workflows.
Can you tell me how to go about with this.

There is a form on the portal. User enters some details there. Then there is 
a submit button. when the user presses the submit button, a workflow is 
triggered on the R/3 side. A work item is sent to the manager which has a 
form ( the form's layout and data are the same as that of the portal screen 
). Basically whatever the user enters in the portal screen is sent as a form 
to his manager, who can then approve it or reject it.

Can anyone tell me how this can be done.....the general steps...connectivity 
between portal and R/3 workflow
