When viewing a page that has a Directory, Profile or Profile Display, for a constituent that has multiple or a dual major, you only see one major. You want to know if it's possible to have two majors or multiple majors show on the directory, profile or profile display page, when a user has multiple majors on their record in Raiser's Edge. You may be able to search both majors in the directory and have the expected results returned for each individual search, but you can't see both majors at the same time.
NetCommunity will only pull in the first major listed for the Primary Alumni information. The user can search by multiple majors in the directory part, but only one major will show at a time. For example, let's say John has majors Computer Science and Engineering on his record in The Raiser's Edge. In the directory part, that has the Major field as a search option, a user can search for Computer Science and John will be displayed. A user can then search for Engineering and John will be displayed. However, if a user visits John's Profile Display page, only Computer Science, the first major listed on his record, will be displayed.
