App Module Pooling and Failover

I have a LOCAL web application with a number of separate tasks (App Module A, B and C). The user logs on using JAAS and I want to store a session scope object representing the 'Company' to which that user belongs for later access by App Module A, B and C.
As I understand it (probably wrong), I should NOT store the 'Company' on the HTTP session state in order to maintain failover provided by the framework.
If this is the case where would 'Company' reside. Would obtaining the 'Company' at the start of each App Module (A, B and C) and setting it as a transient attribute be the correct technique ?

If pooling is turned off, each request to the server is passivated (normally into the db) and reload from there for the next request. This take time, especially if this is done for hundreds of users.
As John said this solution is not solution, you are just pushing the error to a later point of time when your users complain about a crawling system. You may get other errors when you run your app without pooling, which you must fix as they mean that your app is not activation/passivation save.

Urgent! App module pooling and frames

Hello,
I have this problem which I don't know how to solve:
I have a web page with two frames: page1.jsp and page2.jsp.
both JSPs use an application module of the same type.
I thought that each JSP would get a different instance of the application module from the pool.
However, it seems that they get the same Instance.
This is very annoying as my application module maintains a kind of internal state, which makes concurrent use of the same instance very "risky" at best.
The appModule is currently used as "local" but in the end it will be deployed to JSErver or iAs.
Is there any known workaround?
BTW: i use Jdev 3.1 and 8.1.6.
Thanks for any answer

Transient VO error when app module pooling shut off

Hi,
I am using JDev 10.1.3.3.0 to build an application with ADFBC and JSF.
I am trying to test the application with the app module pooling turned off.
There is one failure I am trying to focus on an solve. What I am trying to is to populate Transient VO xyz, navigate to a dialog page using dialog: where the contents of xyz should be displayed in an af:table.
When AM Pooling is turned on, I see the data.
When AM Pooling is turned off, I have the right number of rows in the table, but I every table cell contains no data. Its like the binding layer does not restore.
Could someone explain why this is the case?

Use of application module pool and ADF Busines Components

Hi to all;
Lets suppose an web application with about 10 CRUD forms and 15 to 20 reports or forms just to query and show data;
That's clear to me, all the advantages of using App modules pool.
But for that reports ..... Just an Read only and Forward Only data ?
I was wondering, if it will be more effective and lightweight if we just take an JNDI JDBC connection query data and show it.
This imaginary application will make use of application module pool to provide that 10 CRUD web forms and in other hand, will have for reports,JNDI data sources;
What are your opinion about having this two architectural approach working together in one application ?
Very thanks;
Marcos Ortega

Hi Deepak;
BC4J in my opinion is great and i am proud to share this opinion with all of you;
As a meter of fact, i post this thread to help me better understand BC4J architecture.
I think that my doubt main point is ...
Are application modules pool's life cycle an extra work , when the job is just to read and show data ?
Perhaps, an document about statefull and/or stateless application service release, help me;
IMHO;
cached data most of the time must to be discarted for reports, always we want to query database directly, View's object ClearCache() method would be called to reports.
I think that it's different, when we are talking about sequent requests when we need to span the session, views and entities states.
Forwards Thanks;

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.
II. Export :
I_List_type :
0 = simple list REUSE_ALV_LIST_DISPLAY
1 = hierarchcal-sequential list REUSE_ALV_HIERSEQ_LIST_DISPLAY
2 = simple block list REUSE_ALV_BLOCK_LIST_APPEND
3 = hierarchical-sequential block list
REUSE_ALV_BLOCK_LIST_HS_APPEND
D. REUSE_ALV_COMMENTARY_WRITE : This is used in the Top-of-page event to print the headings and other comments for the list.
Parameters :
I. it_list_commentary : internal table with the headings of the type slis_t_listheader.
This internal table has three fields :
Typ : H header, S selection , A - action
Key : only when typ is S.
Info : the text to be printed
E. REUSE_ALV_GRID_DISPLAY : A new function in 4.6 version, to display the results in grid rather than as a preview.
Parameters : same as reuse_alv_list_display
This is an example for simple list.
2. BLOCK REPORT
This is used to have multiple lists continuously.
The important functions used in this report are:
A. REUSE_ALV_BLOCK_LIST_INIT
B. REUSE_ALV_BLOCK_LIST_APPEND
C. REUSE_ALV_BLOCK_LIST_HS_APPEND
D. REUSE_ALV_BLOCK_LIST_DISPLAY
A. REUSE_ALV_BLOCK_LIST_INIT
Parameters:
I. I_CALLBACK_PROGRAM
II. I_CALLBACK_PF_STATUS_SET
III. I_CALLBACK_USER_COMMAND
This function module is used to set the default gui status etc.
B. REUSE_ALV_BLOCK_LIST_APPEND
Parameters :
Export :
I. is_layout : layout settings for block
II. it_fieldcat : field catalog
III. i_tabname : internal table name with output data
IV. it_events : internal table with all possible events
Tables :
i. t_outtab : internal table with output data.
This function module adds the data to the block.
Repeat this function for all the different blocks to be displayed one after the other.
C. REUSE_ALV_BLOCK_LIST_HS_APPEND
This function module is used for hierarchical sequential blocks.
D. REUSE_ALV_BLOCK_LIST_DISPLAY
Parameters : All the parameters are optional.
This function module display the list with data appended by the above function.
Here the functions REUSE_ALV_FIELDCATALOG_MERGE, REUSE_ALV_EVENTS_GET, REUSE_ALV_COMMENTARY_WRITE can be used.
3. Hierarchical reports :
Hierarchical sequential list output.
The function module is
A. REUSE_ALV_HIERSEQ_LIST_DISPLAY
Parameters:
I. Export:
i. I_CALLBACK_PROGRAM
ii. I_CALLBACK_PF_STATUS_SET

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.

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.

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:

F4 Help in Module pool and restricting the entries

Hi all,
      I was looking how to give F4 help in module pool program and restrict the number of entries on tht event.
Take a example of VBELN, it is having number of entries so for F4 help we first take all the entries for VBAK for VBELN and then use FM 'F4IF_INT_TABLE_VALUE_REQUEST' and pass the table.
So how can we restrict number of entries initially 200 and then user can input number of hits.
( How to use Callback subroutin ).
   Waiting for valuable additions.
Thanks,
Anmol.

Hi ,
    This is my query, I want to restrict the number of entries fetched by the search help depending on the user input like in standard help.
Like VBELN is having number of records how can we asign a help to field like VBELN( for example ), is there any way to restrict the entries on search help rather than selection all the entries for tht field from database which is not good for performance. Like initially it should fetch 100 or 200 records, then if user want more entries to be fetch he can input the number of entries like in standard help. Any idea on this.
Thanks,
Anmol.

What is dfference between module pool and executable

Hi experts,
I want to create transaction(dialog programming).
i am confusing what's the program type i need to enter.
what is difference .
please help..

Hi Ramesh,
As how others said .. A Module pool programming(Dialog programming) cannot be executed directly. A transaction code has to be assigned to it (in SE93)
So ur program type will be - M
Execution can be done accordingly
1. goto SE93.
2. Type in the Dialog programming name
3. Click Create
4. Give any transaction text
5. Give the program Name ( ur dialog programing name)
6. Give the screen number ( the first screen which u want the users to see and enter the data )
then for running/executing the program give the transaction code ....
All the best
Cheers,
R.Kripa.

Develop large Apps Module wise and Integrate Later

Hi,
What is the best way to develop large applications using JDeveloper in a modular way. For example a team of developers to work on a jdeveloper project that is a single module in a large application and another set of developers to work on a different module in a different JDev project. The idea is to keep the individual module apps manageable and to later integrate these to work as a single application once deployed in the WL server.
Appreciate if someone can point me to a document or a best practice guide to achieve this. I heard may be Hudson a good choice to do this but no idea how to.
Thanks

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

Application Module Pooling

Hopefully someone will be able to help us with this CRITICAL issue we've encountered since moving our application from 9.0.3 to 9.0.4.
Our application has over 140 application modules and relies on the BC4J framework.
Under 9.0.3 we used JDBC connection pooling to control the number of database connections, but since going to 9.0.4 we use application module pooling.
Our settings for application module pooling are currently:
jbo.ampool.doampooling=true
oc4j.userThreads=true
jbo.ampool.initpoolsize=0
jbo.ampool.maxpoolsize=15
jbo.recyclethreshold=7
jbo.ampool.maxavailablesize=7
jbo.ampool.minavailablesize=0
The rest are set to their default values.
We only have 75 or so users on the system at a time (load balanced between 2 servers) and within a matter of hours the application crawls to a halt and dies.
What we are seeing is that while the app modules might release, they do not release their database connection, thus they cripple the database as well as the application servers.
The only way out of this situation is to bounce the oc4j instance on the app servers and "start over"....
I guess what my question is, are those app module pooling settings totally wacky and are there some other settings that I am missing?
Tried going back to using JDBC connection pooling but that breaks the application (guess something changed with 9.0.4).
The application servers themselves are fairly beefy, 4GB of RAM and 2 procs, I would hope they would be able to handle a scant 40 users each...

does anyone have any ideas on this??
