The group function allows multiple members to share information such as Bill of Materials (BOM), quotation history and order history as one group.
By using the group function, procurement of parts can be done more efficiently across multiple departments and divisions as well as within the same department.

You can give viewing/editing authority to each member regarding ordering, changing member information, bookmark browsing, BOM function, order history and quote history.

After the member who has “Change member information” authority logs in, they can add a member by going to My Page > Group Member Function > Add Member. If you wish to add someone who does not have an account, you can add them as a newly registered member from the same page.
