Hi Johnny,
Not exactly. If you remove the GP process from the role you will be left with an empty role. GP process differ to what you would be normally use to in terms of portal role structures.
They are an encapsulated series of steps.
What you would have to do is identify what step in the GP process via GP design time you wish
to have alone in a role. I am not sure what this would be doing, but for example if it was
accessing the backend transaction SU01, you would then need to create an Application Integration iView (transaction iView) and set this to launch SU01. You could then attact this iView to the role.
Hope this helps.
Best regards,
Carl
