Search Help

There are two types of search help:
1)Elementary search helps describe a search path.
2)Collective search helps combine several elementary search helps. A collective search help thus can offer several alternative search paths.

Maintance views may not be used as the selection method for search helps.Normally a database view is used.However, you should note that database views(in R/3 system) are always created with an inner join.Sometimes values should be determined with outer join.In this case you should choose a help view as selection method.

A search help exit is a fnction module having a standardized interface.The function module F4IF_SHLP_EXIT_EXAMPLE can be used as template.
