Скачать или смотреть Insert Operation in New Syntax

In ABAP’s new syntax, checking data availability is simplified and more readable compared to the classic READ TABLE approach. Instead of using SY-SUBRC explicitly, developers can now use the LINE_EXISTS, LINE_INDEX, or FILTER expressions directly within logical conditions. For example:

IF line_exists( it_data[ field = 'X' ] ).
" Entry exists
ENDIF.


This eliminates the need for separate read statements and subrc checks, making the code concise and self-explanatory. Similarly, DATA(result) = it_data[ key ] can be used with inline declarations, throwing a runtime error if the entry doesn’t exist, or wrapped in TRY...CATCH for controlled handling. With these constructs, new syntax makes availability checks cleaner, safer, and easier to maintain.
