Finally a hardware renewal of the

       the two. In the near future these interfaces will also help integrate the Hazardous Materials/Health and Safety reporting
       relationship between the two.

       access it from there. In addition MIT has a web interface called SAPWeb which users can use for SAP requisitioning. Later
       this year there are plans to integrate a Web Application Server for SAPWeb.
       Various updates and upgrades are planned for SAP in the next couple of years. A highlight of these include the following.
