Enterprise Portal for Material Management

Hi,

We are trying to find out if there is a way to provide a portal to access SAP MM.

I want to know if there is any scenario where SAP Enterprise Portal is required to Access MM Procurement details. If yes, can some one brief me about it. It is required for a demo, and We need some information regarding this. It will be really helpful if you experts can help me.

Regards,
