ABAP Addition 1 ... FOR {TABLE|NODE} node 2 ... HELP-REQUEST 3 ... VALUE-REQUEST 4 ... AS SEARCH PATTERN
What does it do? These additions for the statement PARAMETERS are only possible in the selection include of a logical database. They must be used to assign a node in the logical database to the parameter. Subroutines for self-defined helps can be called and a special parameter can be defined for evaluating the search help associated with the logical database.
Latest notes:If logical databases are no longer created, then these additions of the statement PARAMETERS no longer need to be used either. • FOR TABLE PARAMETERS (obsolete) • FOR NODE PARAMETERS (obsolete)
ABAP Addition
What does it do? With this addition, the parameter has to be assigned to anode of the structure of the logical database. If a node belongs to type T, the addition TABLE can be used instead of NODE. For a description of the node types, see the NODES statement.
When the selection screen of anexecutable program associated with the logical database is generated, input fields are created only for those parameters for which an interface work area for the assigned node (or a node beneath it in the hierarchy) is declared using NODES or TABLES in the executable program. When using the function module LDB_PROCESS, the assigned node node must be requested so that the parameter appears on the selection screen. • HELP-REQUEST PARAMETERS (obsolete)
ABAP Addition
What does it do? This addition specifies that the para_hlp subroutine (para is the name of the parameter) of the database program of the logical database is called if the user selects the F1 field help for a screen element of the parameter on the selection screen. If the subroutine is not available, the addition is ignored.
If the parameter is defined in ABAP Dictionary with a reference to a data type, the field help that is defined there is not displayed.
Latest notes:In the called subroutine, the field help display can be programmed or called using suitable function modules, such as HELP_OBJECT_SHOW. If the input help is selected, no other selection screen events can be triggered and there is no automatic pass by value between the selection screen and the program. • VALUE-REQUEST PARAMETERS (obsolete)
