Workflow approval process outside SAP

[Swami Bala]

Hello All,
 
We have Qmanagement notification sent out to suppliers/vendors in case of
material defect through workflow. The supplier receives the email sent out
by workflow with defect information etc.,We have also designed webgui screen
which will facilitate the supplier to login in to our SAP workflow inbox -
through internet - whenever he has taken corrective action on the defective
material. Is this a right approach ? I feel that by providing SAP user
access to suppliers we have already wasted some of our SAP license ( we have
only license for 100 SAP users. ) .Is there a better solution like creating
a web interface between SAP and vendors ? I am not that familiar with ITS
interface.
Since it involves SAP workflow I thought I would put up this question in
Workflow forum.
 
Any replies are appreciated.
