Description

The function modules READ_SPFLI_INTO_TABLE and READ_SPFLI_INTO_TABLE_NEW read all data from the database table SPFLI where the key field CARRID matches the import parameter id into the internal tables itab or jtab. If no suitable data can be found, exceptions are raised.

• In READ_SPFLI_INTO_TABLE, the non-class-based exception NOT_FOUND is raised by MESSAGE ... RAISING.

• In READ_SPFLI_INTO_TABLE_NEW, the class-based exception is raised CX_NO_FLIGHT_FOUND by RAISE EXCEPTION ... MESSAGE. CX_NO_FLIGHT_FOUND implements the interface IF_T100_DYN_MSG.

Otherwise, the table is passed to the caller as an export parameter.

The actual parameters carrier and itab or itab have the same data types as the corresponding interface parameters of the function module. The exceptions are handled. The relevant exception text is accessed in different ways.

• In non-class-based exceptions, it is implicitly available via system fields.

• In class-based exceptions, it is specified by attributes of the exception object.
