Module pool- mandatory field
hi all,
i have got 3 radio buttons
when i click first button it should ask me that, enter the value in text field i.e it should be mandatory.....
this is my code.......
IF ADD = 'X'.
RES = VAR1 + VAR2.
ELSEIF SUB = 'X'.
if var1 > var2.
RES = VAR1 - VAR2.
else.
message E001(zabc) with 'error'.
endif.
ELSEIF MUL = 'X'.
RES = VAR1 * VAR2.
ENDIF.
for ur information i manage the beloe code........
loop at screen.
if ADD = 'X'.
IF SCREEN-NAME = 'VAR1 '.
screen-REQUIRED = '1'.
ENDIF.
endif.
ENDLOOP.
but exactly where to write this code........
regards,
Pawan
Hi,
in AT SELECTION_SCREEN event write your code:
if add = 'X'.
if var1 is initial and var2 is initial.
message .....
endif.
endif.

Custom module pool + Amount field decimals display same as standard screen display
Hi All,
Requirement: A custom module program screen field has to be designed which displays decimal values of amount fields same as amount fields in standard screen.
Standard screen behavior: If the standard screen fields are observed, they refer to data elements WRBTR or AZSOL_F05A (transactions FB50/FB03/FB01). However, number of decimal places that are visible on screen are dependent on the currency that is provided.
Both the data elements have 2 decimal places.
For currency USD two decimal places are displayed - in TCURX - decimal places are two.
For currency JPY or CLP - zero decimal places are displayed - in TCURX - decimal places are zero.
i.e., even though the screen field refers to data element or domain that has the characteristic to show 2 decimal places, based on currency, decimal places are adjusted.
I would like to know how this is happening on standard screen fields.
Solution Required for: How to make the custom screen amounts to display same number of decimal places as standard screen amount fields.
P.S: Before posting the query here, research has been done in SDN and other places. It has been identified that quantity fields adjustments are discussed. However for amount field even though discussed earlier, did not reach a conclusion.
I would like to get a solution for this one.
Thanks in advance.
Goutham.Thank you all for taking time to take a look at this query.
This issue has been resolved.
Resolution: If the standard transactions (FI transactions in specific) are observed, whenever there is a field that displays amount value, there will be a corresponding field (may not be beside the amount field, somewhere on the screen or in the same sequence of screens) where the currency key value would be entered.
For instance, if you look at FB50 - there is field on top for the user to input currency key value (like USD or CLP or INR).
When any amount field is declared - this currency key field is provided as the reference field in the screen attributes of the amount field.
In short, in the custom module pool program, provide a field that holds currency key value and use this field as reference field for the amount fields.
Do repond to this thread if the resolution is not clear.
Thank you all once again.

Module-pool screen field value under POV event
Hi All,
I have one issue...please suggest me solution for this.
In module-pool program i have one screen(1000) which has one field(hrname_1000).
Under this event:
PROCESS ON VALUE-REQUEST.
FIELD hrname_1000 MODULE hrname_1000.
under this module hename_1000 i have used F4IF_INT_TABLE_VALUE_REQUEST to put a search help for field hrname_1000.
after that i am trying to retrive HR related stuff's based on the field on module-pool i.e i am using hrname_1000 in the where condition.
but problem is that im not getting value for hrname_1000 which im giving in the module-pool screen.
thats y my select query is not working.
Where as im getting values for the hrname_1000 under PBO & PAI.
It will look like below.
PROCESS ON VALUE-REQUEST.
FIELD hrname_1000 MODULE hrname_1000.
(under the above module)
SELECT DISTINCT ename plans FROM pa0001 INTO CORRESPONDING FIELDS OF TABLE itab WHERE stell = '50001026'.
LOOP AT itab INTO wa WHERE ename = hrname_1000.
ENDLOOP.
Please suggest
Thanks & regards
AnsumeshIn some of the cases the screen field is present in the screen but not holding the value in the required structure or field.
so here u need to check the option of reading the screen field values explictly..
//once u hit an enter and do the f4 i think the value will be there ...but if u dont hit enter and do an F4 the value cannot hold and i think u r in this case ..
1.Fill the screen field name in the structure dynpread.
DATA: BEGIN OF DYNP_VALUES OCCURS 10.
INCLUDE STRUCTURE DYNPREAD.
DATA: END OF DYNP_VALUES.
DYNP_VALUES-FIELDNAME = 'HRNAME_1000'.
APPEND DYNP_VALUES.
* read screen values
CALL FUNCTION 'DYNP_VALUES_READ'
EXPORTING
DYNAME = HELP_REPID "call the repid of ur prog
DYNUMB = HELP_DYNNR "pass the screen number
TABLES
DYNPFIELDS = DYNP_VALUES
EXCEPTIONS
OTHERS = 1.
now dynp_values hold the field name and field value of the screen .
now
SORT DYNP_VALUES BY FIELDNAME.
READ TABLE DYNP_VALUES WITH KEY 'HRNAME_1000' BINARY SEARCH.
IF SY-SUBRC EQ 0.
HELP_XXXX = DYNP_VALUES-FIELDVALUE. "store the value into a variable
TRANSLATE HELP_XXXX TO UPPER CASE.
ENDIF.
Now check the code with the value if its getting populated which once there will make ur select work ..

Module pool screen field should default without pressing enter
Hi
I have got a main module pool screen which has a tabstrip with four tabs.
There are 2 fields in the main screen when we select from F4 for the first field then the field 2 should default in case of a condition.
This happens only when i press enter. I want the second field to change as soon as the first field is selected.
How do I trigger the PAI as soon as the field 1 is selected.
eg: Field 1 : i/p
Field 2 : display
Field 3 : i/p
On F4 for field 1 say i select value 'A' then the valu for field 3 should default to value 'B'. Also field 2 should be displayed based on combination of field 1 and field 2. But now it does it only on pressing enter.
How do I solve this problem?Also if i select field 1 value A and dont press enter and go to the subscreen tab then it does not do any thing. It allows to go on the subscreen tab. But actually it should default the field 3 value. It does it only when I press enter.
Also the F4 is from dictionary that is the screen fields are from dictionary. I have not created any F4 for the fields.
Please help me solve this problem
Regards,
mozilaHi
You can achieve this using List Box only not by Input Field. Since Input field doesn't trigger automatic PAI/PBO
Go through the below thread
populate drop down menu based on entry in another field
or an alternative is--> In PBO use POPUP_GET_VALUES Fm to get the First input field based on that you can enter further values

Pool table
A database table defined in the ABAP Dictionary whose database instance is assigned to more than one table defined in the ABAP Dictionary. Multiple pool tables are assigned to a table pool in the database. The key fields of a pool table have to be character-type fields. The table pool's primary key consists of two fields: TABNAME for the name of a pool table, and VARKEY for the interdependent contents of the key fields in the corresponding pool table. The non-key fields of the pool table are stored in compressed format in their own column, called VARDATA, of the table pool. The only way to access pool tables is by using Open SQL. Joins are not allowed.
Table Pool
Database table in the database that contains the data of several pool tables.
Cluster Table
Database table defined in the ABAP Dictionary, whose version on the database is not only assigned to one table defined in the ABAP Dictionary. Several cluster tables are assigned to a table cluster in the database. The intersection of the key fields of the cluster tables forms the primary key of the table cluster. The other columns of the cluster tables are stored in compressed form in a single column VARDATA of the table cluster. You can access cluster tables only via Open SQL, and only without using joins.
Table Cluster
Database table in the database that contains the data of several cluster tables.
Note: Never mix up with a database table that has the necessary structure for storing data clusters in database tables and in the shared memory. Those are called INDX-type, with reference to the database table INDX supplied by SAP. Data clusters are groupings of data objects for transient and persistent storage in a selectable storage medium. A data cluster can be processed using the statements IMPORT, EXPORT, and DELETE FROM

SCREEN WITH FIELDS
Introduction to Dialog Programming
Transactions
A transaction is a program that conducts a dialog with the user. In a typical dialog, the
system displays a screen on which the user can enter or request information. As a reaction on
the the user input or request, the program executes the appropriate actions: it branches to the
next screen, displays an output, or changes the database.
Example
A travel agent wants to book a flight. The agent enters the corresponding data on the
screen. The system either confirms the desired request, that is, the agent can book the flight
and the customer travels on the desired day on the reserved seat to the chosen destination,
or the system displays the information that the flight is already booked up.
To fulfil such requirements, a dialog program must offer:
_a user-friendly user interface
_format and consistency checks for the data entered by the user
_easy correction of input errors
_access to data by storing it in the database.
ABAP/4 offers a variety of tools and language elements to meet the requirements stated
above in the dialog programs.
Structure of a Dialog Program
A dialog program consists of the following basic components:
P.Naganjana Reddy
Screens (dynpros)
Each dialog in an SAP system is controlled by dynpros. A dynpro (Dynamic PROgram) consists of a screen and its flow logic and controls exactly one dialog step. The flow logic determines which processing takes place before displaying the screen (PBO-Process Before Output) and after receiving the entries the user made on the screen (PAI-Process After Input).
The screen layout fixed in the Screen Painter determines the positions of input/output
fields, text fields, and graphical elements such as radio buttons and checkboxes. In addition, the Menu Painter allows to store menus, icons, pushbuttons, and function keys in one or more GUI statuses. Dynpros and GUI statuses refer to the ABAP/4 program that control the sequence of the dynpros and GUI statuses at runtime.
ABAP/4 module pool
Each dynpro refers to exactly one ABAP/4 dialog program. Such a dialog program is also called a module pool, since it consists of interactive modules. The flow logic of a dynpro contains calls of modules from the corresponding module pool. Interactive modules called at the PBO event are used to prepare the screen template in accordance to the context, for example by setting field contents or by suppressing fields from the display that are not needed. Interactive modules called at the PAI event are used to check the user input and to trigger appropriate dialog steps, such as the update task.
All dynpros to be called from within one transaction refer to a common module pool. The dynpros of a module pool are numbered. By default, the system stores for each dynpro the dynpro to be displayed next. This dynpro sequence or chain can be linear as well as cyclic. From within a dynpro chain, you can even call another dynpro chain and, after processing it, return to the original chain.
Transferring Field Data
How do I display fields known in an ABAP/4 module on the screen? How do I transfer
user entries on the screen to the module? In contrast to report programming, you cannot write field data to the screen using the WRITE statement. The system instead transfers data by comparing screen field names with ABAP/4 variable names. If both names are the same, it transfers screen field values to ABAP/4 program fields and vice versa. This happens immediately before and immediately after displaying the screen.
Field Attributes
For all screen fields of a dynpro, field attributes are defined in the Screen Painter. If a
field name in the screen corresponds to the name of an ABAP/4 Dictionary field, the system automatically establishes a reference between these two fields. Thus, a large number of field attributes in the dynpro is automatically copied from the ABAP/4 Dictionary. The field attributes together with data element and domain of the assigned Dictionary field form the basis for the standard functions the dynpro executes in a dialog (automatic format check for screen fields, automatic value range check, online help, and so on).
Error Dialogs
Another task of the dynpro processor is to conduct error dialogs. Checking the input data is carried out either automatically using check tables of the ABAP/4 Dictionary or by the ABAP/4 program itself. The dynpro processor includes the error message into the received screen and returns the screen to the user. The message may be context-sensitive, that is, the system replaces placeholders in the message text with current field contents. In addition, only fields whose contents is related to the error and for which a correction may solve the error can accept input.
P.Naganjana Reddy
Data Consistency
To keep data consistent within complex applications, ABAP/4 offers techniques for
optimizing database updates that operate independent of the underlying database and correspond to the special requests of dialog programming. For more information on database updates, see Programming Database Updates.
Dynpro
Each screen contains fields used to display or request information. Fields can be text strings, input or output fields, radio buttons, checkboxes, or pushbuttons. The screen of Transaction TZ10 contains only texts and input/output fields.
An SAP dynpro consists of several components:
Flow logic: Calls of the ABAP/4 modules for a screen.
Screen layout: Positions of the texts, fields, pushbuttons, and so on for a screen.
Screen attributes: Number of the screen, number of the subsequent screen, and others.
Field attributes: Definition of the attributes of the individual fields on a screen.
SCREEN PAINTER
You create and edit all components of a dynpro in the Screen Painter. To call the Screen
Painter, create a dynpro in the Object Browser or double-click on an existing dynpro. The Object Browser then calls the Screen Painter. There, you can enter the flow logic of the new dynpro. By pressing the corresponding pushbutton you can maintain the Screen attributes, branch to the Full Screen-Editor or you choose the pushbutton Field list and change the attributes of fields.
Screen Attributes
From the users point of view, a transaction is a sequence of screens, displayed one after
another. How do I determine this sequence? The transactionss attributes determine the first screen to be displayed. The attributes of the individual dynpros determine which screen to display
P.Naganjana Reddy
after the current screen. You can also set the number of the subsequent screen dynamically from within the ABAP/4 program.
Layout
Choose Fullscreen to go to the screen editor. Here you can determine the layout of the
screen. For Transaction TZ10, the desired fields can be copied from Table SPFLI of the
ABAP/4 Dictionary.
Field Attributes
To display and modify the attributes of the individual fields (input/output fields, input
required, possible entries button, invisible, and so on), use the Field list.The fields Company (SPFLI-CARRID) and Flight number (SPFLI-CONNID) are defined as input/output fields. All other fields are used only for outputting the flight data.
Flow Logic
The flow control code of a dynpro consists of a few statements that syntactically ressemble ABAP/4 statements. However, you cannot use flow contol keywords in ABAP/4 and vice versa. You enter the flow control code in the Screen Painter as one component of the dynpro.
The flow control for the dynpro of Transaction TZ10 looks like this:
PROCESS BEFORE OUTPUT.
MODULE SET_STATUS_0100.
PROCESS AFTER INPUT
MODULE USER_COMMAND_0100.
The PROCESS statement names the event type for the dynpro and the MODULE statement tells the system which ABAP/4 routine to call for this event. In this example, there is only one MODULE for each event PBO and PAI. However, an event can contain several statements with several keywords. (The flow control language contains only few statement types. The most important are MODULE, FIELD, CHAIN, LOOP, CALL SUBSCREEN.) To display information on the statement syntax in the flow logic, choose Utilities Help on... in the flow logic editor. In the subsequent dialog window, mark Flow logickeyword, enter the name of the desired keyword, and press ENTER.
ABAP/4 Module Pool
In the Object Browser, the module pool code belongs to one of the following categories:
Global fields: data declarations that can be used by all modules in the module pool
PBO modules: modules that are called before displaying the screen
PAI modules: modules that are called in response to the user input
Subroutines: subroutines that can be called from any position within the module pool.
You use the ABAP/4 Dictionary to store frequently used data declarations centrally. Objects defined in the Dictionary are known throughout the system. Active Dictionary definitions can be accessed by any application. Data defined in the Dictionary can be included in a screen or used by an ABAP/4 program. You declare global data in the TOP module of the transaction, using the TABLES, STRUCTURE, LIKE statements and others. Transaction TZ10 accesses the Dictionary definition of Table SPFLI to provide the desired flight data display. If the TOP include contains the TABLES: SPFLI declaration, all modules in the module pool can access the table fields of
P.Naganjana Reddy
Table SPFLI. The PAI module USER_COMMAND_0100 checks which pushbutton the user activated (CASE OK_CODE). The Display pushbutton in Transaction TZ10 has the function code
SHOW. (For more information on handling function codes, see Processing User Requests). The program then tries to select those records in the SPFLI database that correspond to the data the user entered. The WHERE condition determines matching records by comparing the fields SPFLI-CARRID and SPFLI-CONNID with the database key fields CARRID and CONNID. As soon as a matching record is found, the database transfers all accompanying SPFLI fields to the program table.
When the screen is displayed again, the complete information appears in the output fields
of the screen. The system automatically displays these fields, since the ABAP/4 field names SPFLI-CARRID and SPFLI-CONNID are the same as the screen field names.
In the PBO module STATUS_0100 of Transaction TZ10, the screen 100 receives a GUI status (using SET PF-STATUS) and a GUI title (using SET TITLEBAR):
SET PF-STATUS TZ0100.
SET TITLEBAR 100.
A GUI status is a subset of the interface elements used for a certain screen. The status
Comprise those elements that are currently needed by the transaction. The GUI status for a transaction may be composed of the following elements:
The GUI title is the screen title displayed in the title bar of the window. In contrast to the
GUI status that can be used for several screens, a GUI title belongs to one screen.To create and edit GUI status and GUI title, you use the Menu Painter. To start the Menu Painter, create a GUI status or GUI title in an object list in the Object Browser (or double-click on an existing status or title).
Interaction between Dynpro and ABAP/4 Module Pool
In its most simple form, a transaction is a collection of screens and ABAP/4 routines, controlled and executed by a dialog processor. The dialog processor processes screen after screen, thereby triggering the appropriate ABAP/4 processing for each screen. For each screen, the system executes the flow logic that contains the corresponding ABAP/4 processing. The control passes from screen flow logic to ABAP/4 code and back.
The sequence of events for Transaction TZ10, for example, looks like this:
P.Naganjana Reddy
1.
In the PBO event, the statement MODULE STATUS_0100 passes control to the corresponding ABAP/4 module.In the ABAP/4 module pool, the screen to be displayed receives a menu interface.
2.
After processing the module STATUS_0100, control returns to the flow logic.For the PBO event, no further processing is required. The system display the screen and receives entries from the user. The entries are:
the values for the fields Company and Flight number.
the four-character function code that tells which pushbutton the user activated.
3.
The user input triggers the PAI event. The first PAI statement passes control to the ABAP/4 module USER_COMMAND_0100.Module USER_COMMAND_0100 processes the requests of the user.
4. After processing MODULE USER_COMMAND_0100, control returns to PAI. This terminates the dialog.

EXERCISE
Goto to ABAP editor, and enter the program name ZKA_SCREEN.
Declare the tables and call the screen.
In order to create the object, double click on the screen no, you will automatically guided to the screen painter SE51.
P.Naganjana Reddy
Enter the short description and click on the FLOW LOGIC tab.
Uncomment the flow logic, both PAI and PBO.
P.Naganjana Reddy
Now click on the LAYOUT button.
Click on the DICTIONARY/PROGRAM FIELDS WINDOW F6 button. Type in the table name and click on GET FROM DIC button and select the fields required for the screen and click on the COPY button.
P.Naganjana Reddy
Now drag and place the INPUT/OUTPUT fields box on the screen.
Now click on the TEXT FIELD button and place in the screen and stretch the box for the size required. Now double click on the box, U will get the attributes screen. Enter the name and Text for the field.
P.Naganjana Reddy
Now we need to place the bush buttons. So Click on the push button on the left side and place it on the screen. Double click on it, u will get the attributes screen. Enter the name, text and the icon required and mainly the FCTCODE. It is the one which links the screen painter with the code.
Once everything is set up, SAVE, CHECK and ACTIVATE the screen.
P.Naganjana Reddy
Click on the BACK button. U will be guided to the FLOW LOGIC screen.
Double click on PAI, Because for the screen painter with the fields, Process After the Input is done and so u will guided to the Editor screen.
P.Naganjana Reddy
Now we need to set the System-Uses commands which links the code to the Editor.
So the conditions would be:
IF SY-UCOMM = 'DISPLAY'.
SELECT SINGLE * FROM ZKA_CENTER WHERE CENTERNO = ZKA_CENTER-CENTERNO.
ELSEIF SY-UCOMM ='SAVE'.
INSERT ZKA_CENTER.
ELSEIF SY-UCOMM = 'REFRESH'.
CLEAR ZKA_CENTER.
ELSEIF SY-UCOMM = 'GOTO'.
LEAVE TO SCREEN '0002'.
ELSEIF SY-UCOMM = 'EXIT'.
LEAVE PROGRAM.
ENDIF.
If u create many screens and need links between the screens then u can use GOTO to guide to the other screen.
SAVE, CHECK and ACTIVATE and click on TEST.
P.Naganjana Reddy
Now click on the DISPLAY button.
Also verify with SAVE, REFRESH and EXIT buttons. Thus the screen painter.

TABLE CONTROL
Basic form
CONTROLS ctrl TYPE TABLEVIEW USING SCREEN scr.
Effect
Creates a table control ctrl of the type TABLEVIEW . The reference screen for the initialization is the screen scr . Area of use The table control (referred to here as TC ) facilitates the display and entry of one-line, tabular data in dialog transactions. The functional scope has been defined so that you can implement many typical set operations usually handled by an elementary STEP-LOOP with the standard methods of a TC . Functional scope
Resizeable table grid for displaying and editing data.
Column width and column position modifiable by user and by program.
Storing and loading of user-specific column layout.
Selection column for line selection with color selection display.
Variable column headers as pushbuttons for column selection.
Simple selection, multiple selection, Select/deselect all.
Scrolling functions (horizontal and vertical) via scroll bar.
Fixing of any number of key columns.
Setting attributes for each cell at runtime.
Programming The data exchange between the application and the SAPgui is achieved with a STEP-LOOP , i.e. an ABAP/4 module is called to transfer data for each page.
Example
Processing without an internal table
PROCESS BEFORE OUTPUT.
LOOP WITH CONTROL ctrl.
MODULE ctrl_pbo.
ENDLOOP.
PROCESS AFTER INPUT.
LOOP WITH CONTROL ctrl.
MODULE ctrl_pai.
ENDLOOP.
In this case, the module ctrl_pbo OUTPUT is called once for each output line before the screen is displayed, in order to fill the output fields. After the user has entered data on the screen, the module ctrl_pai INPUT is executed to check the input and copy the new contents.
Example
Processing with an internal table
P.Naganjana Reddy
PROCESS BEFORE OUTPUT.

Here, the system fills the output fields before displaying the screen by reading the internal table itab. When the user has entered data, the module ctrl_pai INPUT must be executed to check the input and to refresh the contents of the internal table. Vertical scrolling with the scroll bar is followed by the event PAI for the displayed page. Then, cntl-TOP_LINE is increased and PBO is processed for the next page. Program-driven scrolling and the most of the functionality described above is achieved by manipulating the control attributes.
Attributes The CONTROLS statement creates a complex data object of the type CXTAB_CONTROL with the name of the control. You maintain the initial values in the Screen Painter and assign the screen with the initial values for a control using the addition USING SCREEN . Initialization is achieved automatically in the "1st access to the control" (setting or reading values). You can use the customizing button (in the top right corner) to save the current setting (column widths and column positions) and use it as the initial value for the next call. All the initial values can be overwritten by the program using the MOVE ... TO TC attributes statement.

TABSTRIP CONTROLS
A tabstrip control is a screen object consisting of two or more pages. Each tab page consists of a tab title and a page area. If the area occupied by the tabstrip control is too narrow to display all of the tab titles, a scrollbar appears, allowing you to reach the titles that are not displayed. There is also a pushbutton that allows you to display a list of all tab titles.
Tabstrip controls allow you to place a series of screens belonging to an application on a single screen, and to navigate between them easily. The recommended uses and ergonomic considerations for tabstrip controls are described in the Tabstrip Control section of the SAP Style Guide.
From a technical point of view, a tab page is a subscreen with a pushbutton assigned to it, which is displayed as the tab title.
The tabstrip control is the set of all the tab pages. Tabstrip controls are therefore subject to the same restrictions as subscreens. In particular, you cannot change the GUI status
P.Naganjana Reddy
when you switch between pages in the tabstrip control. However, they are fully integrated into the screen environment, so present no problems with batch input.
To use a tabstrip control on a screen, you must be using a SAPgui with Release 4.0 or higher, and its operating system must be Motif, Windows 95, MacOS, or Windows NT with version 3.51 or higher.
When you create a tabstrip control, you must:
Define the tab area on a screen and the tab titles.
Assign a subscreen area to each tab title.
Program the screen flow logic.
Program the ABAP processing logic.
You must then decide whether you want to page through the tabstrip control at the SAPgui or on the application server. In the first case, each tab page has its own subscreen. In the second, there is a single subscreen area that is shared by all tab pages.
Defining the Tabstrip Control Area and Tab Titles
You define both the tabstrip area and the tab titles in the screen layout. The tabstrip area has a unique name and a position, length, and height. You can also specify whether the tabstrip area can be resized vertically or horizontally when the user resizes the window. If the area supports resizing, you can specify a minimum size for it.
When you define a tabstrip area, it already has two tab titles. Tab titles are technically exactly the same as pushbuttons. To create additional tab titles, simple create pushbuttons in the row containing the tab titles. Tab titles have the same attributes as pushbuttons, that is, each has a name, a text, and a function code. You can also use icons and dynamic texts with tab titles.
Assigning a Subscreen Area to a Tab Title
You must assign a subscreen area to each tab title. There are two ways of doing this:
Paging in the SAPgui
You need to assign a separate subscreen area to each tab title, and define the function codes of the tab titles with type P (local GUI function). In the screen flow logic, you call all the subscreens in the PBO event. This means that all of the tab pages reside locally on the SAPgui.
When the user chooses a tab title, paging takes place within the SAPgui. In this respect, the tabstrip control behaves like a single screen. In particular, the PAI event is not triggered when the user chooses a tab title, and no data is transported. While this improves the performance of your tabstrip control, it also has the negative effect that when the user does trigger the PAI event, all of the input checks for all of the subscreens are performed. This means that when the user is working on one tab page, the input checks may jump to an unfilled mandatory field on another page.
P.Naganjana Reddy
Local paging at the SAPgui is therefore most appropriate for screens that display data rather than for input screens.
Paging on the Application Server
One subscreen area is shared by all tab titles and called in the PBO event. You define the function codes of the individual tab titles without a special function type. When the user chooses a tab page, the PAI event is triggered, and you must include a module in your flow logic that activates the appropriate tab page and assigns the correct subscreen to the subscreen area.
Since the PAI event is triggered each time the user chooses a tab title, this method is less economical for the application server, but the input checks that are performed only affect the current tab page.
Procedure in Either Case
You create the subscreen areas within the tabstrip area. You assign the subscreen areas to one or more tab titles in the Screen Painter by selecting one or more titles. You can also assign a subscreen area to a tab title in the tab title attributes by entering the name of the subscreen area in the Reference field attribute.
The procedure for the alphanumeric Screen Painter is described under Creating Tabstrip Controls.
If you are paging at the SAPgui, create a subscreen area for each tab title. If you are paging at the application server, select all tab titles and create a single subscreen area. The subscreen areas may not cover the top line of the tab area. However, within a tab area, more than one subscreen area can overlap.
Programming the Flow Logic
In the flow logic, all you have to do by hand is include the correct subscreens. The screen flow and data transport to the ABAP program is the same as for normal subscreens. There are two ways of programming the screen flow logic, depending on how you have decided to page through the tabstrip control.
Paging in the SAPgui
When you page in the SAPgui, you must include a subscreen for each subscreen area:
PROCESS BEFORE OUTPUT. ... CALL SUBSCREEN: <area1> INCLUDING [<prog 1>] <dynp 1>, <area2> INCLUDING [<prog 2>] <dynp 2>, <area3> INCLUDING [<prog 3>] <dynp 3>, ... ...
P.Naganjana Reddy
PROCESS AFTER INPUT. ... CALL SUBSCREEN: <area1>, <area2>, <area3>, ... ...
Paging on the Application Server
When you page on the application server, you only have to include a subscreen for the one subscreen area:
PROCESS BEFORE OUTPUT. ... CALL SUBSCREEN <area> INCLUDING [<prog>] <dynp>. ...
PROCESS AFTER INPUT. ... CALL SUBSCREEN <area>. ...
Handling in the ABAP Program
Before you can use a tabstrip control in your ABAP program, you must create a control for each control in the declaration part of your program using the following statement:
CONTROLS <ctrl> TYPE TABSTRIP.
where <ctrl> is the name of the tabstrip area on a screen in the ABAP program. The control allows the ABAP program to work with the tabstrip control. The statement declares a structure with the name <ctrl> . The only component of this structure that you need in your program is called ACTIVETAB.
Use in the PBO event
Before the screen is displayed, you use the control to set the tab page that is currently active. To do this, assign the function code of the corresponding tab title to the component ACTIVETAB:
<ctrl>-ACTIVETAB = <fcode>.
When you page at the SAPgui, you only need to do this once before the screen is displayed. This initializes the tabstrip control. The default active tab page is the first page. After this, the page activated when the user chooses a tab title is set within SAPgui.
When you page on the application server, you must assign the active page both before the screen is displayed for the first time, and each time the user pages. At the same time, you must set the required subscreen screen.
P.Naganjana Reddy
You can suppress a tab page dynamically by setting the ACTIVE field of table SCREEN to 0 for the corresponding tab title.
Use in the PAI event
In the PAI event, ACTIVETAB contains the function code of the last active tab title on the screen. When you page in the SAPgui, this allows you to find out the page that the user can currently see. When you page at the application server, the active tab page is controlled by the ABAP program anyway. The OK_CODE field behaves differently according to the paging method:
Paging in the SAPgui
When you page in the SAPgui, the PAI event is not triggered when the user chooses a tab title, and the OK_CODE field is not filled. The OK_CODE field is only filled by user actions in the GUI status or when the user chooses a pushbutton either outside the tabstrip control or on one of the subscreens.
Paging on the application server
If you are paging at the application server, the PAI event is triggered when the user chooses a tab title, and the OK_CODE field is filled with the corresponding function code. To page through the tabstrip control, you must assign the function code to the ACTIVETAB component of the control:
<ctrl>-ACTIVETAB = <ok_code>.
This statement overwrites the function code of the last active tab page with that of the new tab title. At the same time, you must ensure that the correct subscreen is inserted in the subscreen area. Otherwise, tabstrip controls are handled like normal subscrens in ABAP programs, that is, the ABAP program of a subscreen screen must contain the dialog modules called from the flow logic of the subscreen.
P.Naganjana Reddy
EXERCISE
Goto SE38. Enter the tabstrip program name Eg: ZKA_TABSTRIP and click on the create button.
First we need to declare the tables.
Then use the controls for the tabstrip.
Syntax: <ctrl-name> TYPE TASTRIP.
Now call the screen. Using CALL SCREEN statement.
Double click on the screen no to draw the screen for tabstrip control.
Now uncomment the FLOW LOGIC and click on the LAYOUT.
P.Naganjana Reddy
The flow logic for the tabstrip would be as follows.
PBO:
The PBO is initiated so that the subscreen for the corresponding tab can be maintained.
Syntax:
CALL SUBSCREEEN <sub-screen name> INCLUDING SY-REPID <screen-var>.
PAI:
When the tab is clicked, the corresponding subscren should open
Syntax:
CALL SUBSCREEN <subscreen>.
P.Naganjana Reddy
DRAWING THE TABSTRIP CONTROL:
Click on the TABSTRIP button and place it on the screen for the required size.
Double click on the control and give the name for the tabstrip control in the ATTRIBUTES screen.
Now double click on the tab and fill in the attributes screen for the name and the text.
Also draw the subscreen in one of the tab and refer the same subscreen in the rest of the tabs.
P.Naganjana Reddy
Now in the sub-screens, we need to get the screen for the tabs.
So call an other screen and draw with fields and pushbuttons to perform actions very similar like SCREEN WITH FIELDS (refer screen painter).
Enter the short description and click on the FLOW LOGIC tab.
P.Naganjana Reddy
Uncomment the flow logic, both PAI and PBO.
Now click on the LAYOUT button.
Naganjana Reddy.P
Click on the DICTIONARY/PROGRAM FIELDS WINDOW F6 button. Type in the table name and click on GET FROM DIC button and select the fields required for the screen and click on the COPY button.
Now drag and place the INPUT/OUTPUT fields box on the screen.
P.Naganjana Reddy
Now click on the TEXT FIELD button and place in the screen and stretch the box for the size required. Now double click on the box, U will get the attributes screen. Enter the name and Text for the field.
Now we need to place the bush buttons. So Click on the push button on the left side and place it on the screen. Double click on it, u will get the attributes screen. Enter the name, text and the icon required and mainly the FCTCODE. It is the one which links the screen painter with the code.
P.Naganjana Reddy
Once everything is set up, SAVE, CHECK and ACTIVATE the screen.
P.Naganjana Reddy
Click on the BACK button. U will be guided to the FLOW LOGIC screen.
Double click on PAI, Because for the screen painter with the fields, Process After the Input is done and so u will guided to the Editor screen.
P.Naganjana Reddy
Now we need to set the System-Uses commands which links the code to the Editor.
So the conditions would be:
IF SY-UCOMM = 'DISPLAY'.
SELECT SINGLE * FROM ZKA_CENTER WHERE CENTERNO = ZKA_CENTER-CENTERNO.
ELSEIF SY-UCOMM ='SAVE'.
INSERT ZKA_CENTER.
ELSEIF SY-UCOMM = 'REFRESH'.
CLEAR ZKA_CENTER.
ELSEIF SY-UCOMM = 'GOTO'.
LEAVE TO SCREEN '0002'.
ELSEIF SY-UCOMM = 'EXIT'.
LEAVE PROGRAM.
ENDIF.
The same procedure for the company table as well will lead the screen in the below manner.

How to use module pool program in my custom report?
Hi,
I am developing a custom report in abap. I want to fetch data from a standard module pool program.I want output of this standard module pool program to be used in my standad report.Submit cannot be used with module pool programs. How can i do this?Can u please suggest?HI friend,
For this you can directly use the table fields i.e. each and every module pool screen fields will be having the table name along with its fields (which you can see by double clicking the field and selecting technical settings button) and since it is a standard module pool program that will get populated directly. So you can get the screen field values directly from the table. I think this will help. Please try and let us know wheather it is solved.
Thanks and regards,

Module pool screen element not shown
Hi,
I have a module pool with table control.
I have added a new field to the internal table and included it in layout-checked properties and it is active/shown in output and input enabled
Also, when I checked in PBO debugging, loop at screen, when the screen element is this field, active/input/output = 1
I have activated the program/generated it/logged off from system and logged in again (to take care of refreshing the screen)
The internal table has values for this field.
When I execute the screen directly instead of module pool program, field is shown in table control
But when I execute the module pool program, this field and heading are not shown in table control but empty space allocated for this field is shown.
May I know how can I resolve this.
Thanks!Hi Vasu,

Default Back Button ( F3 ) with mandatory fields ( module pool program )
Guys,
I'm editing another persons dialog program and as mentioned in the subject line, there are mandatory fields. WIthout them being filled, I cannot use the back button to exit the program as it prompts me to first fill the mandatory fields.
How can I get past this?
I did a /h for debug mode and pressed Back but it did not even show the debugger.
Regards,
Kevin<b>Use AT exit-command.</b>
MODULE mod [ AT {EXIT-COMMAND|CURSOR-SELECTION} ]
[ ON {CHAIN-INPUT|CHAIN-REQUEST} ]
[ SWITCH switch ].
Extras:
1. ... AT EXIT-COMMAND
Effect
The statement MODULE of the dynpro flow logic calls the dialog module mod of the ABAP program. You can use MODULE either as a keyword or as an addition of statement FIELD. When using it as an addition, the call of the dialog module depends on conditions for the screen fields.
As a keyword, the statement calls the dialog module mod of the respective ABAP program. At the event PAI, you can use the additions AT and ON to specify conditions for the call of the dialog module.
At the event PBO, you can call any dialog module defined in the ABAP program with the addition OUTPUT. At the events PAI, POH and POV, you can call any dialog module defined with the addition INPUT or without any addition. If the dialog module mod does not exist in the ABAP program, an untreatable exception is triggered. After processing a dialog module in the ABAP program, processing of the dynpro flow logic is resumed after the position of the call, unless the screen processing is completed within the dialog module.
You can use MODULE as a keyword only at the events PBO and PAI. At the events POH and POV, you can use MODULE only as an addition to the FIELD statement.
Note
Do not mix up the MODULE statement of the dynpro flow logic with the identically called statement MODULE for defining dialog modules in the ABAP program.
Addition 1
... AT EXIT-COMMAND
Effect
Addition AT EXIT-COMMAND at the event PAI causes module mod to be called exactly if:
The function used to trigger event PAI has function type "E"
Into the input field of the standard toolbar, the user entered a character string starting with "E" and confirmed it using ENTER.
The dialog module is called before the automatic input checks defined in the system or in the ABAP Dictionary and independent of its position in the event block. The only screen field transported to the ABAP program is the OK field. If the function that triggered the PAI event does not fulfill any of the above prerequisites, the MODULE statement is not executed.
If several MODULE statements have the AT EXIT COMMAND addition, only the first one is executed. If no MODULE statement has the addition AT EXIT COMMAND, a normal PAI processing is executed: The predefined input checks are executed and then the PAI event block is processed sequentially. Provided the screen processing is not terminated in the dialog module mod, after the return from the dialog module, the complete PAI processing is executed. You must not use the addition AT EXIT COMMAND in connection with the statement FIELD.
Note
The function type of a function is determined in the Screen Painter or Menu Painter. Usually those functions of the user interface are defined with function type "E" that are assigned to the icons Back, Exit and Cancel in the standard toolbar of the GUI status. Therefore, the called dialog module should terminate the screen processing and allow security checks, if required.
