Dear Abhilash,
Have you checked the upgrade document released by SAP on migrating from 4.7 to ECC 6.0. It may be possible that certain standard functionality might have been enhanced/changed which could affect your output. In this case you may have to align your program accordingly. SAP note search with MP keywords can also be helpful.

Strange problem in module pool programming

Hi all,
we have a module pool program which consists of screen 100 and 200 and 3 sub-screens 201,202 and 203.the problem is when we double click on any field we get a pop up message which should appear only when we press the 'SAVE' button for which ok_code is 'CHNG'.I have debugged the program for screen 100 pbo,pai,200 pbo but the value of ok_code is not equal to 'CHNG' then it takes me to screen 200 and when i double click then popup appears and and in 200 PAI the value of ok_code had already got changed to 'CHNG' without entering the change logic and I have not even pressed the SAVE button which has 'CHNG' code associated with it.Can any one help me solve this problem.I wish I could give a better explanation.
Thanks and Regards,
Sangram

Hi,
This is because the Shortcut key assigned to SAVE button in PF-STATUS is "F2". F2 is for Double Click. Assign some other Function Key to SAVE or any Button. Try to avoid assigning F2 key.
This would solve the problem.

Select-options Problem in module pool

Hi,
I have created select-options in a seperate program and i have called the subscreen in module pool program.
I dont have any problem with the display of select-options but whatever the value given is not getting in to the program. Hw to solve this problem
Assured Points
Thanks in Advance
Jai

hi,
did you declare that in top include?
if not declare it globally.
In stead of subscreen, try to do with screen itself.
Create screen like this.
selection-screen begin of screen 300.
selection-screen begin of block b1 with frame title text-000.
select-options : so_ebeln for v_ebeln modif id g1,
so_vbeln for v_vbeln modif id g2.
selection-screen end of block b1.
selection-screen end of screen 300.
Call this screen : in PAI of ur another screen.
call selection-screen 300.

Selection screen problem in module pool

Hi friends,
I am working on module pool programming, I need to put select screen on the screen of the module pool porgramming. I used Input/Output field to do that and activated. But I am getting message invalid field format (screen error) can any one tell me why I am not able to run the seletion screen when I am using input/output field, also please let me know how to solve this problem.
Regards,

Hello,
Think that this is useful for u/
SELECTION-SCREEN - Defining selection screens
Variants:
1a. SELECTION-SCREEN BEGIN OF SCREEN scr.
1b. SELECTION-SCREEN END OF SCREEN scr.
2. SELECTION-SCREEN BEGIN OF SCREEN scr AS SUBSCREEN.
Effect
Defines a selection screen with the number scr. scr may be up to 4 digits.
SELECTION-SCREEN BEGIN OF SCREEN scr.
Additions:
(zu SELECTION-SCREEN BEGIN OF SCREEN scr) 1. ... TITLE title
2. ... AS WINDOW
Notes
In reports (type 1 programs), a selection screen with number 1000 is created automatically when you use the SELECT-OPTIONS, PARAMETERS and SELECTION-SCREEN statments. This selection screen appears when you SUBMIT the report.
In any type of program (apart from subroutine pools - type S), you can define further selection screens using SELECT-OPTIONS, PARAMETERS and SELECTION-SCREEN. You enclose these statements between the SELECTION-SCREEN BEGIN OF SCREEN and SELECTION-SCREEN END OF SCREEN statements.
You call these screens using the CALL SELECTION-SCREEN statement.
Screen number 1000 is not allowed (reserved for standard selection screen).
When you generate the program, all user-defined selection screens are also generated.
Within a report (type 1 program), all SELECT-OPTIONS, PARAMETERS and SELECTION-SCREEN statements outside a SELECTION-SCREEN BEGIN/END OF SCREEN block form part of selection screen 100 (standard selection screen)

Problem is Module pool custom F4 help

In module pool selection screen . I have defined vendor field as a select option and attached a custom search help to it . Now the problem is that when i press F4 on that field and select a value from the help , that value is not populated in the input field .
The other problem is that if we keep this vendor select option as blank , then in the select statement using " IN S_lifnr " gives a dump as it treats the field as blank .( does not function as standard) . does this have anything to do with the custom search help .
any help would be appreciated .

Do you mean that u created a custom cearch help using se11 and attached that using F4IF_INT_TABLE_VALUE_REQUEST.
I dont think that is possible.
F4IF_INT_TABLE_VALUE_REQUEST is used to programmatically create an f4 help, fetching data from an internal table.
here is an eg.
DATA: BEGIN OF VALUE_ITAB OCCURS 0,
      moldno TYPE zqmrr-zzmoldno,
      END OF VALUE_ITAB.
DATA: FIELD_TAB LIKE DFIES OCCURS 0 WITH HEADER LINE.
DATA: RETURN_TAB LIKE DDSHRETVAL OCCURS 0 WITH HEADER LINE.
select-options :           s_moldno for zqmrr-zzmoldno,
AT SELECTION-SCREEN ON VALUE-REQUEST FOR S_MOLDNO-LOW.
REFRESH VALUE_ITAB[].
REFRESH FIELD_TAB[].
REFRESH RETURN_TAB[].
SELECT ZZMOLDNO FROM ZQMRR INTO table VALUE_ITAB.
FIELD_TAB-FIELDNAME = 'ZZMOLDNO'.
FIELD_TAB-TABNAME   = 'ZQMRR'.
APPEND FIELD_TAB.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
   DDIC_STRUCTURE         = ' '
      RETFIELD               = FIELD_TAB-FIELDNAME
    TABLES
      VALUE_TAB              = VALUE_ITAB
     FIELD_TAB              = FIELD_TAB
     RETURN_TAB             = RETURN_TAB
   DYNPFLD_MAPPING        =
EXCEPTIONS
   PARAMETER_ERROR        = 1
   NO_VALUES_FOUND        = 2

Problem creating module pool

I'm trying to create dialog program ( probably referred to as a module pool in today's terminology) in R/3 4.7 and I'm getting authorization errors when I use the naming convention I have always used SAP + M + Z + program name. For example if my program name was TEST the dialog program name would be SAPMZTEST. In creating this program I answer yes to creating the top include, then yes to the proposed name of the top include which is MZTESTTOP. Then I get stopped by the authorization error.
My question is this: Is there a new way to create dialog programs in 4.7 or is this merely an authorization problem - if so, what value needs to be the object entry of S_DEVELOP
I would greatly appreciate some guidance on this
Thanks,
Brent

I did that and the basis guys responded that we are only authorized to create programs in the Y & Z name space. I tried to explain that there was a particular naming convention for module pools.
I just wanted to make sure that there is no change in the naming convention, and no change in the way those programs are created.
Thanks,
Brent

Problem in module pool with table control scrolling

hi,
i am using the table control in module pool,in the table control i have radion button for all the rows.
After i got the data into the table control ,if i select radio button and if i press vertical scroll bar button, that radio button is deselecting,how to solve this issue.
Please help me.

Hi
Generally we don't keep radiobuttons in table control for selecting the records
We keep check boxes for selecting the records
Radio button is used to select a single from a group of records and at a time only one is selected, where as checkboxes at a time you can select a single or multiple.
So use checkboxes and code correctly see the doc for Table control
syntax:
CONTROLS .
if you only want to determine the row of the table control. SY´-SUBRC allows you to check if the cursor is placed in a row of a table control.
u need to comment the performs of table control fields and write ur own perform statements. And u have to declare the table control fields as separate internal tables.
Go through this urls.

Problem in Module Pool Programming

hello,
I am using module pool programming.
i want to assign the text to textbox during runtime
thanks!

Hi Raghvendra Bhanap,
declare the variable with the same name of text box(In module pool) and in the PAI even write the module by double clicking on that in your program just assign some text to that name then the text automatically come in that text box.
See this example programm.
*In Screen Painter PAI Event.*
moudle assigntext.
In your Program.
Data w_name(40). (*In the module pool also put this name only)
Module assigntext.
w_name = 'Raghvendra Bhanap'.
Endmodule.

Selection OPTION: Date input problem in Module POOL through Subscreen

Dear ALL,
Being new to ABAP, I am struck in a Problem.
Requirement:
I want an option on the Screen( My Screen 9000) for Date Range. Through this Date-Range I want to filter and pull some data from
Database.
As Date Range Selection option is possible only through Sub-Screen integration. Hence I integrated a Sub-Screen 400 (as below) and named the Sub-Screen area as SEL on my screen.
Problem: As soon as I enter the dates on the screen, then those dates are not taken up by the code.
During debugging I saw the the S_datum-low and S_datum-high are empty (in fact 00000000)
The code follows:
PROCESS BEFORE OUTPUT.
MODULE STATUS_9000.
Call SUBSCREEN SEL INCLUDING sy-repid '400'.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_9000.
DATA: gv_datum     Type   dats,
SELECTION-SCREEN BEGIN OF SCREEN 400 AS SUBSCREEN.
    SELECT-OPTIONS: s_datum FOR gv_datum.
SELECTION-SCREEN END OF SCREEN 400 .
Plz help where I am missing something.
Regards
Chandan

Problem in Connection pooling after deploying BC4J App Module as EJB

Hi,
We have deployed the application modules on standalone OC4J as stateful EJB session beans.
The problem is that with each user, the number of database connections seem to increase. This is making the application unscalable, which defeats the purpose of using EJB!
Can someone please suggest how to limit the number of database conections in this scenario?
Can this be solved by application module pooling? How can we use the PoolMgr to work with the session beans?
We have tried to invoke disconnect on the application module after calling methods(using appmodule.disconnect(true)) and reconnect (appmodule.reconnect()) on entering the method. This keeps the number of connections low and works the first time the method is invoked. But subsequently, it gives nullpointerexception when the Row is accessed in the JSP.
The exception we are getting is :

<AppServerConnectionName>StandaloneOC4JConnection</AppServerConnectionName>
<AppModuleJndiName>Supplier.SupplierAM</AppModuleJndiName>
<java.naming.security.credentials>admin</java.naming.security.credentials>
<DeployPlatform>EjbIas</DeployPlatform>
<java.naming.security.principal>admin</java.naming.security.principal>
<DtMiddleTierDeploymentProfile>ProjectMiddleTier.deploy</DtMiddleTierDeploymentProfile>
<ApplicationName>Supplier.SupplierAM</ApplicationName>
<DtDeploymentProfile>ProjectEJB.deploy</DtDeploymentProfile>
<DtCommonDeploymentProfile>ProjectCommon.deploy</DtCommonDeploymentProfile>
<JDBCDataSource>jdbc/ConnectionCoreDS</JDBCDataSource>
<jbo.server.internal_connection>jdbc/ConnectionCoreDS</jbo.server.internal_connection>
<jbo.ejb.txntype>local</jbo.ejb.txntype>
<jbo.doconnectionpooling>true</jbo.doconnectionpooling>
<ApplicationPath>ProjectEJB</ApplicationPath>
</AppModuleConfig>
The Datasource used (in $ORACLE_HOME/j2ee/home/config/data-sources.xml) is:
<data-source
          class="oracle.jdbc.pool.OracleConnectionCacheImpl"           connection-driver="oracle.jdbc.driver.OracleDriver"
          ejb-location="jdbc/ConnectionDS"
          inactivity-timeout="30"
          location="jdbc/ConnectionCoreDS"
          name="ConnectionDS"
          password="*******"
          pooled-location="jdbc/ConnectionPooledDS"
          url="jdbc:oracle:thin:@<IPADDESS>:<SID>"
          username="USER"
          xa-location="jdbc/xa/ConnectionXADS"
          max-connections="5"
          min-connections="1"/>

Can this be solved by application module pooling? How
can we use the PoolMgr to work with the session
beans?You can use a stateless checkout/checkin appmodule.
Take a look at the following help topics which explain this in good detail.
"About Application Module Pooling"
"About JSP Pages and Application Module Pooling"
The pool can help reuse the appmodule instance across requests thus reducing the number of concurrent db sessions.

Problem in custom infotype module pool

Hi experts,
I have created custom infotype using PM01 where i am showing fields Basic and HRA. When I enter the value for Basic, automatically the calculation for HRa should be done depending on formula. Also, the HRA fields should be only output field. When I do the changes in the module pool PBO and regenerate the object , the changes I made get disappered. Do I have to create Z of the includes. If so, how to assign it to the infotype? Please help me to solve this problem since its urgent.
Thanks in advance.
Proper solution would be rewarded.

C
This is the flavour of Infotype.
When you regenerate the Infotype, you are again reassigning the Chanrecterstcis of your Infotype. so the Existing will get regenerated with the Standard Code.
To avoid this what I suggest you is.
After finishing the Regeneration then edit the Module pool of the Infotype basically Screen 200 then add your code and Activate it there itself. Hope you got it.
If you again Regenerate it you loose your Code.
If you have further Questions please let me know.
