SELECT-OPTIONS - ldb_options
Short Reference
ABAP Syntax(Obsolete) ... [ HELP-REQUEST [ FOR {LOW|HIGH} ] ]
[ VALUE-REQUEST [ FOR {LOW|HIGH} ] ] ...
ABAP_ADDITIONS:
1 ... HELP-REQUEST [ FOR {LOW|HIGH} ]
2 ... VALUE-REQUEST [ FOR {LOW|HIGH} ]
What does it do? These additions for the statement
SELECT-OPTIONS are only possible in
the selection include of a
logical database . They can be used
to access subroutines for user-defined help.
Latest notes: If logical databases are no longer created, you do not need
to use the additions of the statement SELECT-OPTIONS .
ABAP_ADDITION_1 ... HELP-REQUEST [ FOR {LOW|HIGH} ]
What does it do? If you specify this addition, the program accesses the
subroutine selcrit_hlp when the user chooses the field help
F1 for an input field in the
selection criterion . The subroutine selcrit_hlp must be
defined in the database program on
the logical database, where selcrit stands for the name of the
selection criterion. You can specify FOR LOW or FOR HIGH
to access either the subroutine selcrit-low_hlp or the subroutine
selcrit-high_hlp , depending on whether the field help is
selected for the first or second input field. The addition does not
affect the other field. If one of the subroutines does not exist,
choosing F1 for the input field has no effect.
If the selection criterion is defined with reference to a data type in
the ABAP Dictionary, the field help defined there for the corresponding
field is not displayed.
Latest notes: The subroutines can be used in the same way as a
PARAMETERS statement to program a field
help.
ABAP_ADDITION_2 ... VALUE-REQUEST [ FOR {LOW|HIGH} ]
What does it do? If you specify this addition, the system accesses either
the subroutine selcrit-low_val or selcrit-high_val ,
depending on whether the user chooses the input help F4 on the
first or second input field in the
selection criterion . The subroutines selcrit-low_val and
selcrit-high_val must be defined in the
database program for the logical
database, where selcrit stands for the name of the selection
criterion. If you specify FOR LOW , the addition only affects the
first input field, and if you specify FOR HIGH , it only affects
the second.
If one of the subroutines does not exist, choosing F4 for the
input field has no effect. If the selection criterion is defined with
reference to a data type in the ABAP Dictionary, the input help defined
there for the field in question is not displayed.
Latest notes: The subroutines can be used in the same way as a
PARAMETERS statement to program a field
help. When the user chooses the input help, this does not trigger any
other selection screen events
and there is no automatic value transfer between the
selection screen and the program.
