To give access rights of the BOM module, to the users in the new project, you must assign these users to a project/product group/discipline combination using the Administration > Users, User Access for Projects, User Access for Product Groups screens. Furthermore, you must assign a suitable role (to be defined on Roles and Menus) and a BOM User view name (to be defined on BOM User View) to the user on the User Access for Projects screen to grant the necessary access authorizations.
By means of the BOM User view name, you define the layout of the Multi Position View (MPV) on the Maintain BOM screen.
