MODULE POOL and selection screen

Hello Friends,
I need some help in ABAP. Please give me the overview, how to go about it?
My scenerio is:
I want to write an ABAP code which will display drop down list(list will have few years mentioned in it) on the first screen.
Thn after selecting the year I would like to display months corresponding to that year(it can be in the same screen or some other screen). Now when the user enters some details as per the months, he should het some output after execution(on the same screen or the other).
Please help me with it, so that I can proceed with my deelopment.
Looking forward for your reply.
Regards,
Lokesh

Hi,
Use this link, simple steps to learn to display data in ALV Grid.
https://www.sdn.sap.com/irj/scn/wiki?path=/display/snippets/learn%252bto%252bdisplay%252bdata%252bin%252balv%252bgrid
That was a basic sample code to display data in first alv, now follow the below steps to make it interactive.
When you double-click on any cell of alv grid, use this code to fetch the data of the line that you currently clicked, its working:-
When you double click on the ALV grid line, you will have sy-ucomm = '&IC1'.
So when you define a i_callback_user_command for the FM reuse_alv_grid_display, and create it as:-
FORM command USING ucomm LIKE sy-ucomm selfield TYPE slis_selfield.
DATA : ok_code TYPE sy-ucomm.
ok_code = ucomm.
CASE ok_code.
WHEN '&IC1'. "for double click on alv grid line
" your code
ENDCASE.
ENDFORM.
As you have used selfield TYPE slis_selfield, the field selfield will hold all the values.
To know on which row you have clicked and to retain that line, use code:-
Suppose you are currently displaying data from internal table itab and corresponding to it you have work area wa.
Now to know the field name that you clicked, use:-
selfield-fieldname " will fetch you the name of field that you clicked
Now using the work-area and the name of field that you clicked, you can easily make out the details of the field i.e., field name and field value and you can code as per your requirement.
Now here you can create a new field catalog and call another FM 'REUSE_ALV_GRID_DISPLAY' to display further information in the next grid based on the value obtained when user double clicks a cell.
Hope this helps you.
Thanks & Regards,
Tarun Gambhir

Module Pool with Selection Screen

I have a module pool in which I've created a sub screen to accommodate select-options.
SELECTION-SCREEN BEGIN OF SCREEN 1010 AS SUBSCREEN.
select-options: r_matnr for mara-matnr.
selection-screen end of screen 1010.
I've put this selection screen in an include of the module pool.
Now I can't seem to see my variable, r_matnr, in the program. How to I pass the value to the program and what have I done wrong. Perhaps where I placed the selection-screen.
Any help would be appreciated.
PS... I can see my screen but when I put the debug on, no value is in r_matnr.
Thanks Marianne

Hi Mariane,
Placing the selection screen declarations in an include does not make any issues. Can you please check your code. For your reference, I am placing a simple piece of code, in which I am also calling a selection screen from within a module pool and displaying the output of the select options. Execute this code and check what is the difference between your code and this.

Module Pool and Smart Form

Can anybody Provide me good step by step procedure for module pool and smart for programming with screenshot.
my email Id is [email protected]

Hi,
A module pool is a collection of screens, flow logic, menu bars and ABAP code that you use to build an application. Typically the transaction code that calls the application will refer to the module pool and the initial screen number.
-->What are the requirements a dialog program must fulfill ?
A dialog program must fulfill the following requirements
. 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.
What are the basic components of dialog program ?
Screens (Dynpros)
Each dialog in an SAP system is controlled by dynpros. A Dynpro consists of a screen and its flow logic and controls exactly one dialog step.
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.
What is a dynpro ? What are its components ?
A dynpro (DYnamic PROgram) consists of a screen and its flow logic and controls exactly
one dialog step.
- The different components of the dynpro are:
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
What is screen flow logic? What are the selections in it? Explain PAI and PBO?
Ans - Screen flow logic contains the procedural part of a screen. The screen flow logic is like an ABAP program in that it serves as a container for processing blocks. There are four event blocks, each of which is introduced with the screen keyword PROCESS:
PROCESS BEFORE OUTPUT.
PROCESS AFTER INPUT.
PROCESS ON HELP-REQUEST.
PROCESS ON VALUE-REQUEST.
Selections are performed in PAI.
PROCESS BEFORE OUTPUT (PBO) is automatically triggered after the PAI processing of the previous screen and before the current screen is displayed. You can program the PBO processing of the screen in this block. At the end of the PBO processing, the screen is displayed.
PROCESS AFTER INPUT (PAI) is triggered when the user chooses a function on the screen. You can program the PAI processing of the screen in this block. At the end of the PAI.
processing, the system either calls the next screen or carries on processing at the point from which the screen was called.
PROCESS ON HELP-REQUEST (POH) and PROCESS ON VALUE-REQUEST (POV) are triggered when the user requests field help (F1) or possible values help (F4) respectively. You can program the appropriate coding in the corresponding event blocks. At the end of processing, the system carries on processing the current screen.
step by step process of dialog programing:
Firstly, you can go to Tcode SE80 and here create a package.
On that package name right click and select program.
Then choose program type modulepool program.
Similarly, you can create screen and then select layout and drag and drop labels and pushbuttons as per your requirements.. Then double click on th push buttons.You will see property window and there we will find FCTCODE and there type the names e.g suppose you want to
display then typy on the fctcode Display or any name as you wish.
After that save and activate it. and then close the window.
And then go back to the intial screen .
And then click Flow logic button and then uncomment the statement
module status_1000 PBO block and then doible click on status_1000
save and activate and then go back and then PAI block uncomment the statement module status_1000 and the dobule click on status_1000.
step by step process of creating smartforms:
1.        What is Smartforms?
Smartforms is a tool to create and maintain forms for mass printing in SAP Systems. Just like sapscripts, for Smart
forms print program is used to create the output internal table which in turn is thrown to the smart form where the
field values are displayed. The output medium for Smartforms support printer, fax, e-mail, or the Internet.
Transaction Code: SMARTFORMS
To print a form the program for the data retrieval and a Smartform that contains the entire form logic is required. As
these two are separate one should adapt the Smartform if changes to the form logic are necessary. The application
program passes the data via a function module interface to the Smartform. When activating the Smartform the system
automatically generates the function module.
The architecture of the smart form is given below:
Creating Forms Using SAP Smart Forms
When creating a form one must:
1.      Retrieve the application data
2.      Describe the form
3.      Pass the application data to the form
Example: Create Smartform for printing Purchase order.
Retrieving the application data (Purchase Order information):
Write an ABAP program (Print Program) to retrieve data or include a retrieval routine into the application. This
code consists of statements that select data from databases according to certain selection criteria. Store the
retrieved data in internal tables, structures or variables and transfer it to the form in one step.
SAP has already provided with the Print Program (/SMB40/FM06P) for Purchase Order. Based on the business
requirement, this Print Program can be copied and modified to get the required data and transfer to Smartform.
Describing the Form:
The user defines the form using a Smartform. Use the tools of the form builder as listed below:
1.        Use the form painter to position the windows, graphics and addresses on a page.
2.        Use the PC editor to write the texts.
3.        Use the table painter to format the tables.
The flow control is used to print the pages and elements.
Form Logic (Introduction)
In the form builder one can describe a Smartform by a set of nodes. To do this, one can build up a tree structure on
the left side of the user interface.
The node global settings and its three successors form attributes, form interface and global definitions always exists
for any newly created forms.
To describe the form logic, create the hierarchy under the node pages and windows.
The following rules apply to control the flow of the form output.
1.        The nodes in the tree structure are processed from top to bottom.
2.        For each node there is a tab, this can be used to link the node to a condition. If the condition is true, the
system processes the node. If not, it skips the node and all its successors.
3.        One should define a next page for each page.
The SAP form builder of the smart form consists of:
1.        Form painter for creating the layout of the form
2.        PC Editor for entering texts and fields into output areas
3.        Navigation tree for maintaining the form logic
4.        Table painter for creating templates and tables
To define the text formats, one can use the Smart Styles.
Style builder:
On the left of the style builder screen consists of the predetermined nodes (header data, folder for paragraph
formats, and folder for character formats).
On the right one can see the maintenance screen with its tab pages. At the bottom the preview of the selected font
can be viewed.
Create Purchase Order Smartform
Create a Smartform, copy the existing SAP provided purchase order Smartform to ZSFM_PURCHASEORDER for
customizing as per business requirement.
1. Form Settings under Global Settings node, set the parameters in Output Option:
Page Format: Letter
Character per Inch: 20
Line per Inch: 6
Style: ZSTM_SMB40_SF
Output Format: Standard Output
2.        Form Interface
We can add parameters in the Import Parameters and tables in Tables tab of the form interface for the application
data to be available for the Smartform to print.
3. In Global definition we can define the all the global variables which can be used in Smartforms. Initialization
can be used for initializing the variables and even for retrieving the data.
Creating pages:
Each form consists of one or more pages. The first page in the tree structure is the start page and the
processing of the form starts with this page itself.
1.        Open the context menu for existing page node and choose create®page
2.        Enter a unique name (FIRST) for the node and a description (Page)
3.        Determine the format (1, 2, 3...)and the mode of the page counter (Increase counter) on the general
attributes tab
4.        Determine the print attributes (Portrait Format) of the page on the output options
5.        Determine a background graphic for the entire page on the background tab (Not used in PO).
Creating windows:
The size and position of the window can be graphically set in the form painter. There are main windows and
secondary windows. The difference between these two is that the output in a main window can cover several
pages.
1.        Open the context menu for an existing page node and choose®window
2.        Enter a name for the node (NAMEFORM) and a description (Title Window).
3.        On the general attributes indicate type of window. NAMEFORM is secondary window.
In similar fashion all the other windows are created and positioned as per the form design. Only one MAIN
window is created, it is used for line items which can cover several pages.
Positioning texts on the form
The texts are displayed in the form using text nodes. The only exceptions are addresses.
The predecessor node of the text node determines its use:
Predecessor node        Used to
Secondary window        Position text on one or more pages
Main window        Display text in relation to other nodes in the main window, it may cover several pages
Template         Displays texts for table cells of a static table
Table        Display table contents
There are three text types:
1.        Text element : to enter new text in the PC editor
2.        Text module : to include a text module
3.        Include text : to include an existing SAPscript text
Entering texts in PC editor: (TITLE)
·        To create a text node call the context menu for that node in the tree structure that should receive the
text, then choose->text
·        Enter a unique name (TITLE) for the node and the node description (TITLE)
·        On the general attributes tab choose text element as text type
·        In the text node box choose whether the text should be started with a new paragraph or only in a new
line
·        Enter the text in the PC editor. Text could be a program element like &Title& or Purchase Order. &Title&
is a variable for which the value is assigned in Program line before the text.
Including text modules: (TERMSCONDITION)
Text module of the text node is used to refer to an existing text module in the system. The text modules can be
used in two ways:
·        To create a text node, call the context menu for that node in the tree structure that shall contain the text
and choose create->text under the window TERMSCONDITION.
·        Enter a unique name for the node (TERMSCONDITION) and a description (Terms and Condition)
·        On the general attributes tab select the text type text module
·        Enter the name of the text module in the text name field (&G_TERMS_TEXT&). &G_TERMS_TEXT& is
used to determine the Text name dynamically in the program lines preceding the text module node.
·        Program Lines: GETTERMSCONDITION
Concatenate 'ZTMM_PO_TERMS_' ZXEKKO-BUKRS
                                  INTO G_TERMS_TEXT.
Including SAPscript texts: (HD_TXT_F01 Order Header Text)
The text type include text node to refer to a SAPscript text, which already exists in the system. To identify the
text the text name, object, id and the language is needed.
·        To create the text node, call the context menu for that node in the tree structure that shall receive the
text and choose create -> text under the main window.
·        Enter a unique name (HD_TXT_F01) for the node and the node description (Order Header Text).
·        On the general attributes tab choose include text as text type
·        Text Name - &ZEKKO-EBELN&, Text Object EKKO, Text ID F01, Language - &SY-LANGU&. Also check
mark No error if no text exists.
Tip: Since the size of text is not known, its better to have the text in MAIN window, so that it can run to more
than one page if required.
Inserting addresses: (SENDER):
Address node is used to insert an address into the form. This guarantees that the address is formatted
according to the postal rules of the sender country.
·        To create an address node , call the context menu for that node in the tree structure that one wants to
contain the text and choose create->Address
·        Enter a name for the node (COMPANY_CODE_ADDRESS) and a description (Company Code Address)
·        Determine the address type (Organization Address) on the general attributes tab
·        For organizational addresses - specify the address number, for any other - specify the person number
and the address number. In this case we get the company code address into variable &ADDNR&, so we need
program lines (SENDER) preceding the address text.
·        In the box additional addresses, attributes to specify how to display the address are maintained.
Printing graphics: (LOGO):
Tcode SE78 is used to import graphics into the SAP system. The transaction imports the graphics and stores it
in the BDS (business transaction server) and then it can be displayed in the form.
·        To create the graphic node , call the context menu for that node in the tree structure and choose create-
>graphic
·        Enter a name (LOGO) for the node and the description (Logo Graphic)
·        On the general attributes determine whether a colored or a black and white
·        On General Attributes use the fields object - GRPAHIC, id BMAP and name - &G_LOGO& to identify the
graphic. &G_LOGO& is variable and therefore we can print company code specific logo. Program line preceding
the graphic is required.
·        Program line COMP_LOGO is used to assign the value to G_LOGO. Concatenate 'ZCOMPANY_LOGO_'
ZXEKKO-BUKRS INTO G_LOGO. So, the name of graphic for example will be ZCOMPANY_LOGO_0202 for
company code 0202.
Displaying a static table (Window INFO, Template - TEM_INFO)
Use node type template to display a table whose layout and size is determined before the runtime of the print
program.
To create a template, define a table layout to determine the cell structure for each line. The cells are used to
display the cell structure for each line. The cells are used to display the contents of the successor nodes of the
template node.
·        Create Template under the INFO window node. Create > Template.
The template layout is used to determine the following,
1.        The number of lines and cells
2.        The height of each cell
3.        The width of each cell
4.        The alignment of the table in the window
5.        Whether and where to display separator lines or frames
Use the table control on the template tab to define the layout of the lines. Each line of the template must have
a definition.
Use the pattern box to select the desired table pattern.
Displaying contents in cells: (TLE_CONTACT)
The template node defines the table layout. The successor nodes of the template         determine the data to be
displayed in the table cells.
In General Attributes choose Text type Text Element. In editor, type DTE         Contact.
In Output Options, define the output structure LINE 5 and Column 1.
Similarly all other information for each cell can be filed using the text module and         address module.
Displaying Dynamic Table (ITEM_TABLE)
·        Create TABLE under the MAIN window node. In DATA Tab, loop through the data internal table.
L_XEKPO is the item table which has all the line item details.
Define the line types based on the positioning of the text in main window. For         example: TABLE_HEADER1
is used for positioning Header texts in the table.
·        Table is divided into three parts: Header, Main Area and Footer.
·        Header is used for printing the Header Title of the table and it at the start of the table on every page.
·         Main Area is used to print the line item details of the PO. Create a line (ITEM_DETAIL) of the line type
TABLE_HEADER1. It will dynamically generate number cells based on the line type defined in the table layout.
Name all the cells as per the usage. For each cell create the text node to display the information. For example:
Cell VAL_MATERIAL, Text node MATNR is created which has text element - -matnr.
·        Footer is used for printing the information after Main Area data is printed. This can be used for Total
printing or any other information which needs to be printed after all line items are printed. Create line
TLE_CONTR_STP for Contractual Stipulation of the line type LINE which has only one column. Create the
text element to print the information.
Special Requirement: Printing the Acknowledgement text if the order value is greater then USD 50,000.00 on
the second copy only.
·        This requirement needs the modification in the print program and the Smartform.
·        Modification in Print Program to trigger the second copy if the order value is greater then 50K. Its
advisable to copy the standard print program to custom Z program (Z_SMB40_FM06P), and changes should
be made to Z program. Number of copies is passed from NAST to ls_composer_param-tdcopies in Smartforms.
The value ls_composer_param-tdcopies is modified in the print program to 2 if the order value is greater then
50K.
·        The printing of Acknowledgement Text only on second copy is achieved using the COPIES WINDOW in
Smartforms. Define Window ACKN_COPY of the type COPIES WINDOW and Output to Only Copies Copies
Differ. Also set the condition in the Condition Tab of the window SFSY-JOBPAGES = 1, so that it only print
on the first page of the copy.
·        If user selects to print 2 copies and the order value is more then 50k, program needs to print 2 sets
meaning 4 copies. So number of copies is taken care of in Print program but again the printing of
Acknowledgement Text should be only the Even number copy meaning Copy# 2 and 4. This achieved by using
the program lines to determine the even copy. SFSY-COPYCOUNT will tell us the current copy number being
printed.

vineela.

ALV
ABAP List Viewer
The common features of report are column alignment, sorting, filtering, subtotals, totals etc. To implement these, a lot of coding and logic is to be put. To avoid that we can use a concept called ABAP List Viewer (ALV).
This helps us to implement all the features mentioned very effectively.
Using ALV, We can have three types of reports:
1. Simple Report
2. Block Report
3. Hierarchical Sequential Report
There are some function modules which will enable to produce the above reports without much effort.
All the definitions of internal tables, structures and constants are declared in a type-pool called SLIS.
1. SIMPLE REPORT.
The important function modules are
a. Reuse_alv_list_display
b. Reuse_alv_fieldcatalog_merge
c. Reuse_alv_events_get
d. Reuse_alv_commentary_write
e. Reuse_alv_grid_display
A. REUSE_ALV_LIST_DISPLAY : This is the function module which prints the data.
The important parameters are :
I. Export :
i. I_callback_program : report id
ii. I_callback_pf_status_set : routine where a user can set his own pf status or change the functionality of the existing pf status
iii. I_callback_user_command : routine where the function codes are handled
iv. I_structure name : name of the dictionary table
v. Is_layout : structure to set the layout of the report
vi. It_fieldcat : internal table with the list of all fields and their attributes which are to be printed (this table can be populated automatically by the function module REUSE_ALV_FIELDCATALOG_MERGE
vii. It_events : internal table with a list of all possible events of ALV and their corresponding form names.
II. Tables :
i. t_outtab : internal table with the data to be output
B. REUSE_ALV_FIELDCATALOG_MERGE : This function module is used to populate a fieldcatalog which is essential to display the data in ALV. If the output data is from a single dictionary table and all the columns are selected, then we need not exclusively create the field catalog. Its enough to mention the table name as a parameter(I_structure name) in the REUSE_ALV_LIST_DISPLAY. But in other cases we need to create it.
The Important Parameters are :
I. Export :
i. I_program_name : report id
ii. I_internal_tabname : the internal output table
iii. I_inclname : include or the report name where all the dynamic forms are handled.
II Changing
ct_fieldcat : an internal table with the type SLIS_T_FIELDCAT_ALV which is
declared in the type pool SLIS.
C. REUSE_ALV_EVENTS_GET : Returns table of possible events for a list type
Parameters :
I. Import :
Et_Events : The event table is returned with all possible CALLBACK events
for the specified list type (column 'NAME'). For events to be processed by Callback, their 'FORM' field must be filled. If the field is initialized, the event is ignored. The entry can be read from the event table, the field 'FORM' filled and the entry modified using constants from the type pool SALV.

Difrence between module pool and dialog programming

Hi abapers,
can plz tell me difrence between module pool and dialog programming.

Hi,
Actually Dialog Programming is Module pool Programming.
Please go thru this , see if your dbout gets clear.
Basic components of dialog program?
- Screens (Dynpros)
- Each dialog in an SAP system is controlled by dynpros.A dynpros consists of a screen
And its flow logic and controls exactly one dialog step.
- 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.
Regards,
Priyanka.

What is meany By Module Pools and Functional Pools

Hi gurus,
I want to know what are module pools and functional pool. If any of you have some information on it, I would be glad if you can share it with me
Regards
Jason

Hi Jason
Module pool is a type of program that contains steps of screens and can only be executed with a transaction code or menu function.
function-pool is the introductory statement for programs of type Function Group, these are programs in which you can define function modules.
Take a look at this:

Hi Experts ,

but problem is that i have to maintain selection text and text element for every program .

Thanks and Regards
Priyank Dixit

Hi again,
1. I tried the same thing - include bdcrecx1
   and it only provides radiobuttons, parameters and checkboxes.
   The labels/text elements are totally empty.
PS: Only after we GOTO--->Text Elements
     and again activate them, (by ticking the 'dictionary checkbox or entering some appropriate text);
do they appear properly in the selection screen.

Hi Hariharan,
I would recommend you to use primarily use push button and then after SUBMIT statement, and also the example for the same is provided below:
*Code used to execute a report
SUBMIT Zreport.
*Code used to populate 'select-options' & execute report
DATA: seltab type table of rsparams,
      seltab_wa like line of seltab.
seltab_wa-selname = 'PNPPERNR'.
seltab_wa-sign    = 'I'.
seltab_wa-option = 'EQ'.
* load each personnel number accessed from the structure into
* parameters to be used in the report
loop at pnppernr.
    seltab_wa-low = pnppernr-low.
    append seltab_wa to seltab.
endloop.
SUBMIT zreport with selection-table seltab
                                via selection-screen.
*Code used to populate 'parameters' & execute report
SUBMIT zreport with p_param1 = 'value'
                with p_param2 = 'value'.
Please validate the same at your end as well, please come back, if inputs are required.

I have created a Screen on which one field is created Say Bank Name. I would like to give some spcific value for this fileld where user can select only seeing in drop down cann't enter.
Can anyone tell how can we do it ?

Hi,
The selected value key will be stored in the parameter.
eg: Refer below code. Here if i select Vinod then po_name will be 1. After this read i_values WITH this key and get the actual value.
PARAMETERS: po_name(30) TYPE c VISIBLE LENGTH 20 AS LISTBOX.
TYPE-POOLS: VRM.
DATA: i_values TYPE vrm_values,
      wa_values LIKE LINE OF i_values.

wa_values-key = '1'.
wa_values-text = 'Vinod'.
APPEND wa_values TO i_values.
wa_values-key = '2'.
wa_values-text = 'Kumar'.
APPEND wa_values TO i_values.
wa_values-key = '3'.
wa_values-text = 'Reddy'.
APPEND wa_values TO i_values.
CALL FUNCTION 'VRM_SET_VALUES'
       EXPORTING
            id              = 'PO_NAME'
            values          = i_values

            id_illegal_name = 1
            OTHERS          = 2.
START-OF-SELECTION.
READ TABLE i_values INTO wa_values WITH KEY key = po_name.
MOVE wa_values-text TO w_name. " This will be ur actual value.
Thanks,

Abap objects and selection screen

Hello everybody,
I am interested in your ways of implementing selection-screens in the style of ABAP Objects.
In earlier times (when I used to implement ABAP objects in a procedural way) I just put the selection-screen commands in an include or a form routine of my ABAP report. So it was possible to run the report in background.
Now I read something about selection-screens/dynpros and "separation of concerns" in the book "ABAP Objects" written by Keller. He advises using function groups to encapsulate presentation from logical matters. (Selection-screen commands are in an automatically generated include now). I implemented this way. (ABAP report with a local class, which has a main method, where function module of the function group is called). It works, but i see no chance to run my report in background now.. but I need to run the report in background.
Does anybody know a solution without deleting function group?
What do you think is the best way of using selection-screen-commands and ABAP Objects, especially regarding running in background?
Thx for your advise in advance.
Kind regards,
Anne

Hi Naimesh,
thx for explanation. I am not sure, if I understood everything in the right way.
Where do you write the code for building the selection-screen? (PARAMETERS, SELECT-OPTIONS etc.)
If you write these commands in a class method, you will get a syntax error ( because it's forbidden per definition of ABAP objects). So, am I right assuming that you put the coding just at the beginning of the ABAP report ? And after START-OF-SELECTION-event you start the processing... ?
Furthermore, I don't really understand why you create an separate class for ALV. I found your "SAP abap help"-blog, where you explained the concept of MVC ((By the way, well done!), but you didn't mention an "ALV class" there..
Mh.. another question - have you ever combined MVC with object services?
At the moment I'm working on a software project where I use object services. I created 2 persistent classes via SE24 and one local class in my ABAP Report.
I don't really see possibility to implement MVC in this project without change very much of coding and class structure...
In my opinion the M (data&business logic) are my existing global classes and my local class is kind of Controller class?!
Thx in advance,
Anne

Module pool ( call multiple screens )

hi abapers,
in module pool program ,
iam call one screen into another screen .
ex : screen no . 100
iam designed table control with some column fields .
iam call one of column field of table control into another screen,
at that time last record value of that field will comes to the other screen.
but i want, what of the selected value of field value comes to the other call screen number.

Hi Raj,
Use GET CURSOR FIELD FNAME VALUE FVAL.
Whis is a syntax for system can identify yhe record i.e we can able to select one record from screen 100 is transferred to screen 120.
FNAME ---> Field Name
FVAL----->Value Which is selected from that Value (screen 100)..

Call transaction MB22, put the cursor on reservation field and press F1, then press either F9 or click on technical information, there you should find the Parameter ID to fill. Here you are lucky there is one so just SET PARAMETER ID and CALL TRANSACTION ... AND SKIP FIRST SCREEN.
Just some remarks.
Were you unlucky (next time ?) you may be required to look at PBO modules (or report event like INITIALIZATION) to find if and where the transaction looks for the initial values.
Remember that the SKIP may not be performed if the dynpro number of the transaction initial screen is statically specified as its next dynpro
If no solution found, you may be required to build a small BDC.

Raymond
