ABAP_DESCRIPTION
The table spfli_tab is a hashed table with an unique primary key and two non-unique sorted secondary keys.
The first LOOP takes place without a key being specified. The table output is in the order in which the table was filled. This means it is sorted by the fields entered after the ORDER BY of the
SELECT statement.
The other two LOOP loops are carried out under the specification of one of the two secondary table keys city_from_to or
city_to_from .
The columns whose sort order were used to output the table are indicated by color.
