ABAP_DESCRIPTION
The table sflight_tab is a hashed table with a unique primary key and a non-unique secondary sorted key. Since a secondary sorted key is specified in the statement MODIFY after USING KEY, it is possible to access the hashed table using the associated secondary table index.
This example only demonstrates the syntax. Generally, instead of using the statement MODIFY, modifications of this type should be made using a field symbol or a data reference: LOOP AT sflight_tab ASSIGNING < sflight_wa> USING KEY plane_type
WHERE planetype = 'A310-300'.
< sflight_wa>-seatsmax = < sflight_wa>-seatsmax + 20.
ENDLOOP.
