SELECT-OPTIONSSELECT-OPTIONS so_car FOR wa_flight-carrid

DEFAULT AA.This creates an internal table (with a header)having the name so_car. The internal table has 4columns SIGN, OPTION, LOW and HIGH.

SIGN I (Include), E (Exclude)OPTION EQ (Equal), NE (Not equal), LE (Less

than or equal), LT (Less than), GE (Greater thanor equal), GT (Greater than), BT (Between), NB(Not between), CP (Contains pattern), NP(Contains pattern not)

LOW or both LOW & HIGH contain values

depending on OPTION value


9/68

SELECT-OPTIONS

The selection is union of all Includes minus the union of all Excludes.

= Union of (Value = CO, Value between AA and BA)Minus

Union of (Value = AB, Value between AF and AZ)

= (AA, AB, AC, AF, AZ, BA, CO) Minus (AB, AF, AZ)

= (AA, AC, BA, CO)

Will select-options make querys where clause complicated for

programmer? No it is easy to use in any where clause as shown below

SAP takes care of the logic.

16/68


(continued)LOAD-OF-PROGRAM.

This event keyword defines an event block whose event is triggeredby the ABAP-runtime environment when an executable program, amodule pool, a function group or a sub-routine pool is loaded in theinternal session. When a program is called using SUBMIT or usinga transaction code, then at every call a new internal session isopened and the event block is executed once at every call. You caninitialize global data objects of the program here. The event block

must be executed completely; otherwise, a runtime error will occur.Therefore, no statements are allowed to be executed that leave theevent block without returning. At the first call of an externalProcedure (sub-program or function module), the frameworkprogram of the called procedure is loaded into the internal sessionof the caller, thus triggering the event LOAD-OF-PROGRAM. Theevent block is executed before the called procedure. At any furthercall of a procedure of the same framework program by a caller ofthe same internal session, the event LOAD-OF-PROGRAM istriggered no longer.


17/68


(continued)INITIALIZATION.

This event keyword defines an event block whoseevent is triggered by the ABAP runtime

environment during the flow of an executable

program, directly after LOAD-OF-PROGRAM and

before the selection screen processing of anyexisting standard selection screen. This gives you

the one-time opportunity to initialize the input fields

of the selection screen, including those defined in

the logical database linked with the program.


18/68


(continued)START-OF-SELECTION.

This event keyword defines an event block for which the event

is triggered by the ABAP runtime environment during the flowof an executable program and before any selection screensare processed. In an executable program, all statements thatare not declarations and that are listed before the first explicitprocessing block, or if the program does not contain any

explicit processing blocks, then all functional statements ofthe program, are assigned to an implicit event block START-OF-SELECTION, which is inserted before any START-OF-SELECTION event blocks. If the program is linked to alogical database, preparatory tasks can be performed at

START-OF-SELECTION before the logical database importsthe data. If the program is not linked to a logical database,this event block becomes a type of main program fromwhich procedures or screens are called.


19/68


(continued)END-OF-SELECTION.

This statement defines an event block, whose eventis raised by the ABAP-runtime environment during

the calling of an executable program , if the logical

database, with which the program is linked, has

completely finished its work.


20/68


(continued)AT LINE-SELECTION.

This statement defines an event block whose eventis triggered by the ABAP runtime environment

during the display of a screen list provided the

screen cursor is on a list line and you select a

function using the function code PICK. Through thedefinition of this event block, the standard list

status is automatically enhanced in such a way

that the function code F2 and, with it, the double-

click mouse function is linked up to the functioncode PICK.


21/68


(continued)END-OF-PAGE.

This statement defines an event block that is raisedby the ABAP-runtime during creation of a basic list,

if there is a line reservation in the addition LINE-

COUNT of the initiating statement for a page

footer, which was reached while writing to thispage. A list output that takes place in the event

block, is placed in this area. Output statements

that exceed the reserved area will be ignored.


22/68


(continued)TOP-OF-PAGE [DURING LINE-SELECTION].

This statement using the option DURING LINE-SELECTION defines an event block

whose event is triggered by the ABAP runtime environment during the creation ofa list. This occurs when a new page is started that is, immediately before thefirst line in a new page is to be output. All list outputs that take place in the eventblock are placed below the standard page header of the list. You cannot outputmore lines than are available in the page within the event block. The NEW-PAGEstatement is ignored within this event block. The entire output written to the list inthe event block belongs to the page header of the current list page. The top page

header cannot be moved when you scroll vertically in a list displayed on thescreen. For each TOP-OF-PAGE event, the placeholders &1 &9 arereplaced with the contents of system fields sy-tvar0 sy-tvar9 in the standardheading and the column headings of the standard page header during creation ofa basic list. You can assign values to these system fields in the program.

If you do not use an addition, an event block is triggered for event TOP-OF-PAGEduring the creation of a basic list. If you use the addition DURING LINE-

SELECTION, an event block is triggered for the corresponding events during thecreation of details lists. You have to use system fields like sy-lsind to distinguishbetween the individual details lists.


23/68


(continued)AT USER-COMMAND.

This statement defines an event block whoseevent is triggered by the ABAP runtime

environment if, during the display of a screen

list, a function with a self-defined functioncode was chosen.


24/68


(continued)AT PF##.

This statement defines an event block whoseevent is triggered by the ABAP runtime

environment during list display provided the

screen cursor is on a list line and a function isselected using the function code PF##. Here

## stands for a number between 01 and 24. In

the= standard list status, these function codes

are assigned to the function keys of the input

device.


25/68


(continued) AT SELECTION-SCREEN

If an error message or warning message is displayed during thisevent, the system makes all selection screen fields ready for input

AT SELECTION-SCREEN ON If an error message or warning message is displayed during this

event, the system makes only the above screen fields ready forinput

AT SELECTION-SCREEN ON

This is available to check entry combinations of a logical group. Allfields in this block are made ready for input when an errormessage is issued

AT SELECTION-SCREEN ON END OF For selections where you can enter any number of single values

and ranges, a different screen is displayed where multipleselections (values and ranges) can be entered, the ATSELECTION-SCREEN ON END OF is executed when thisscreen is processed. See next page for visual

Note: AT SELECTION-SCREEN is Executed last, if below specific one like ATSELECTION-SCREEN ON exists. Both are executed unless the first message isof type error


26/68


(continued)

AT SELECTION-SCREEN ON END OF so_car.

CHECK .

MESSAGE e003(bc405).


27/68


(continued) AT SELECTION-SCREEN ON HELP-REQUEST (F1)

When the user presses F1 on the relevant field, the subsequent processingblock is executed. You can thus implement a self-programmed help for the

input/output fields of the selection screen

AT SELECTION-SCREEN ON HELP-REQUEST FOR so_car.CALL SCREEN 100 STARTING AT 30 03 ENDING AT 70 10.

AT SELECTION-SCREEN ON VALUE-REQUEST (F4) When the user selects this pushbutton or presses F4 for the field, the event

is executed. You can thus implement a self-programmed possible entriesroutine for the input/output fields of the selection screen. If the programcontains such an event and the user presses F4 , the system processes thisrather than displaying the check table or the fixed values of the Dictionaryfield

Note: It is recommended that instead of creating these events for F1 and F4, itis better to use the system F1 and F4 help that retrieves the values fromDictionary. This way F1 and F4 provides uniform look and feel applicationwide.

ABAP Statements for Screen

Display

WRITE

A very important keyword in the reporting area is theWRITE statement. You use WRITE to output literals

or fields on the screen or printer. Subsequent WRITE

statements appear on the same output line, unless a

line feed occurs. If a line is full, the system continuesthe output in the next line.

The simplest form of the WRITE statement outputs a

literal. Remember always to include literals inquotation marks. A simple WRITE statement may be:

WRITE 'My first program'.


32/68

ABAP Statements for Screen

Display NEW-PAGE

Use the NEW-PAGE statement to create a pagebreak in your list. Page breaks improve the clarity ofthe page layout of your list

SKIP Use the SKIP statement to create a line feed. To

create several line feeds, specify the desired numberbehind SKIP. SKIP 5 (This line creates five line feeds)

ULINE

Use the ULINE statement to create a line feed firstand then draw a horizontal line. This statement alsohelps to make lists easier to read

Terminal (user), External and Internal Sessions

When you logon using the SAP Logon icon on desktop youcreate a brand new terminal session.

Generally each GUI window is one external session

You create new external sessions by choosing System >

Create session or entering /o in the command field Each time a new window opens a new external session is

created, unless you use the SAP Logon icon to create asession which will create a new terminal (or user session)

You can have up to six external sessions opened

simultaneously in one terminal session External sessions are subdivided into internal sessions

34/68

Terminal (user), External and Internal

Sessions (continued)

Each program occupies its own internal session

Each time a new program is called its data must be stored

somewhere in memory depending on the requirements Generally each of the called program consists of one internal

session each. You can go back to the calling programs internalsession after the called program completes (or overlay and neverreturn)

We do not observe internal sessions in any visual way becausethey are internal sessions- all we see is one external sessiongenerally represented by one GUI window

Each external session can contain up to nine internal sessions

When a different user logs on a new terminal session is created.The new terminal session starts a new (or first) external session.When the first program is run new (or first) internal session isstarted for that user


35/68


Sessions (continued)To create new Terminal or

User Sessions (or new Logon) use

SAP Logon icon on same or

different workstation. SAP licensingmay not allow one user to have

multiple Terminal Sessions

37/68

ABAP and SAP MemoryABAP memory

ABAP memory is a memory area that all ABAP programs

within the same internal session can access using theEXPORT and IMPORT statements

Data within this ABAP memory remains intact during awhole sequence of program calls

To pass data to a program which you are calling, thedata needs to be placed in ABAP memory before the callis made

The internal session of the called program then replaces

that of the calling program. The program called can thenread from the ABAP memory

If control is then returned to the program which made theinitial call, the same process operates in reverse

41/68

ABAP and SAP Memory

(continued)SAP Memory

SAP memory is a memory area to which all mainsessions within a SAPgui (login or user session)have access

Use SAP memory either to pass data from oneprogram to another within a session, or to passdata from one session to another.

Application programs that use SAP memory

must do so using SPA/GPA parameters (alsoknown as SET/GET parameters)


42/68

GET/SET parameters These are also called SPA/GPA parameters

The most frequent use of GET/SET parametersis to fill input fields on screens

These parameters are reset when you logoff thesessions (exit)

These parameters can be set either for aparticular user or for a particular program usingthe SET PARAMETER statement

Other ABAP programs can then retrieve the setparameters using the GET PARAMETERstatement

Variants Variants allow you to reuse values entered

once on the selection screens. These arehelpful when:

The program is started frequently with same

values

The program is run in the background


50/68

Variants (continued) A variant consists of two parts:

The values entered on the selection screen (example:Value AA for airlines)

The attributes and display attributes of the

parameters and select-options (example: Making

some fields read-only or some not visible, etc)

Note: If you use the INITIALIZATION event to initialize

any variables in the program, the variant will not haveany effect on them (will get overwritten by the

initialization)

Calling programs using Transaction


61/68


CodeMethod 1

LEAVE TO TRANSACTION .

The system terminates the current program and starts the program with

transaction code . The statement is the equivalent of entering /n in thecommand field followed by the transaction code. After the called programthe user returns to the application menu and NOT to the calling program(When using LEAVE TO TRANSACTION, the current call sequence isexited completely.
