ABAP_DESCRIPTION
The following mesh paths are used as mesh path expressions:

Mesh path with forward association as an initial mesh association on the right side of an assignment. The source in the square brackets is a table expression supplemented by a condition. flights-scarr _spfli[ flights-scarr[ carrname = name ]
connid = connection ]

Mesh path with mesh inverse association as an initial mesh association on the right side of an assignment. The source in the square brackets is a table expression. flights-spfli ^_spfli~scarr[ flights-spfli[ carrid = ID
connid = CONNECTION ] ]

Mesh path with path extension after the initial mesh association on the right side of an assignment. flights-scarr _spfli[ flights-scarr[ carrname = name ]
connid = connection
] _sflight[ fldate = date ]
The mesh path with path extension is also used to demonstrate the addressing of a component using the structure component selector, assignments to a field symbol, write access, and usage in the predicate function line_exists.
