Groupware vs SAP Business Workflow

[Kim, Go Joong]

Dear workflowers,
 
I'm now participating in the project at which too many approval workflow
scenarios are must be developed.
And I think it is impossible to develop all scenarios in SAP R/3 in time.
So our team is considering to use groupware.
For example, the approval process is executed in the groupware and the
result is sent to SAP R/3 if approved.
 
Pls let me know If someone knows pros and cons about using groupware.
And are there campanies using groupware in the above situation?
 
Regards,
