Now in ABAP 7.4, you can enhance the functionality of a search help object to display possible search results and further values already while typing in a drop-down box beneath the search field. This assists the user who is searching for the desired entry. In addition, for fuzzy searches you can define an error-tolerant value in order to define the deviation of the relevant results.
With the new internal table constructs in ABAP 7.2 and ABAP 7.4 we have the ability to create ABAP code with fewer statements for the same functionality, without compromising readability of the code. New built-in functions like LINE_INDEX and LINE_EXISTS, and new constructor operators such as CORRESPONDING allow us more flexibility and extensibility when developing and maintaining our ABAP code.
