Help Views
Help views can be used as a selection method in
Search Helps. This is necessary especially if a view with outer join is required for the value selection in the search help. Since database views always implement an inner join, a help view must be selected as selection method in such cases.All the tables used in a help view must be linked with foreign keys. Only foreign keys which have certain semantic attributes can be used here (see
Restrictions for Maintenance and Help Views).
The functionality of a help view has changed significantly between Release 3.0 and Release 4.0! In Release 3.0, a help view was automatically displayed when you pressed the F4 help key for all the fields which were checked against the first table (primary table) of the help view. This is no longer the case in Release 4.0.
As of Release 4.0, you must explicitly create a search help which must be linked with the fields for which it is offered (see
