Table types in Modern ABAP inline declaration

(Inline declaration - new way of declaring variables, field symbols, Internal tables on the fly)

The data type of the new data object is constructed in accordance with the structure of the results set defined after?SELECT and

  Select ebeln,bsart,lifnr from ekko 
                           into table @data(lt_ekko)
                           where aedat ge 20210101 
                           and lifnr eq '10000001'.        

Inline declaration "into table @data(itab)" declares a?STANDARD TABLE?itab with an empty table key.

Inline declaration provides an easy way to declare internal tables and preferred by developers in Modern ABAP. Developers should always keep in mind about volume of data handled by the internal table in production system and create internal tables by declaring SORTED or HASHED table type explicitly if required. This will avoid potential performance issues as SORTED or HASHED tables provides better performance over standard table type.
