ABAP_DESCRIPTION
The system opens two cursors for the tables SPFLI and SFLIGHT
. Since both tables are linked through a foreign key relationship, you can define a nested loop over the tables by sorting the selection by the primary key; the system then reads the data of the inner loop dependently on the data of the outer loop. This way of programming is more efficient than the usage of nested SELECT loops since the cursor for the inner loop needs not be reset again and again. In a control level change in the inner loop, the system temporarily stores the data read until the next loop pass since it is not possible to reset the cursor.
