Performace tuning: how to pass data between different batch job programs?

Hi everyone,
    now i have one problem about performance tuning using threading in SAP programs: split one big program into two programs - one is main program and the other is sub program. using batch jobs, we can submit multi jobs of sub program at the same time.
    does anybody know how to pass data between different batch jobs? I don't want to use temp files. can ABAP memory can implement this?
    thanks!

Wei,
Yes we can transfer the data by using
SAP Memory OR ABAP Memory.
Ex: V_count TYPE i.
V_count = 100.
LOOP AT itab.
IF v_count EQ 25.
Here For every batch job
EXPORT data TO MEMORY ID 'ABC'
   Function module
    JOB_OPEN
   JOB_SUBMIT
   JOB_CLOSE.
ENDIF.
ENDLOOP .
IN your 2nd program.
INITIALIZATION.
IMPORT data FROM MEMORY IF 'ABC'.
FREE memory if .---When you free the memory you will get recent data.

How to pass data between two internal sessions using ABAP memory?

Hi,
How to pass data between two internal sessions using ABAP memory?
It would be fine if you could explain with an example.
And also let me clear about the data passing between two main sessions and two external sessions with specific examples.
Thanks.

Hi ,
check the example.
Reading Data Objects from Memory
To read data objects from ABAP memory into an ABAP program, use the following statement:
Syntax
IMPORT <f1> [TO <g 1>] <f 2> [TO <g 2>] ... FROM MEMORY ID <key>.
This statement reads the data objects specified in the list from a cluster in memory. If you do not use the TO <g i > option, the data object <f i > in memory is assigned to the data object in the program with the same name. If you do use the option, the data object <f i > is read from memory into the field <g i >. The name <key> identifies the cluster in memory. It may be up to 32 characters long.
You do not have to read all of the objects stored under a particular name <key>. You can restrict the number of objects by specifying their names. If the memory does not contain any objects under the name <key>, SY-SUBRC is set to 4. If, on the other hand, there is a data cluster in memory with the name <key>, SY-SUBRC is always 0, regardless of whether it contained the data object <f i >. If the cluster does not contain the data object <f i >, the target field remains unchanged.
In this statement, the system does not check whether the structure of the object in memory is compatible with the structure into which you are reading it. The data is transported bit by bit. If the structures are incompatible, the data in the target field may be incorrect.
PROGRAM SAPMZTS1.
DATA TEXT1(10) VALUE 'Exporting'.
DATA ITAB LIKE SBOOK OCCURS 10 WITH HEADER LINE.
DO 5 TIMES.
ITAB-BOOKID = 100 + SY-INDEX.
APPEND ITAB.
ENDDO.
EXPORT TEXT1
TEXT2 FROM 'Literal'
TO MEMORY ID 'text'.
EXPORT ITAB
TO MEMORY ID 'table'.
SUBMIT SAPMZTS2 AND RETURN.
SUBMIT SAPMZTS3.
The first part of this program is the same as the example in the section Saving Data Objects in Memory. In the example, the programs SAPMZTS1 and SAPMZTS2 are called using SUBMIT. You can create and maintain the programs called using the SUBMIT statement by double-clicking their names in the statement. For further information about the SUBMIT statement, refer to Calling Executable Programs (Reports)
Example for SAPMZTS2:
PROGRAM SAPMZTS2.
DATA: TEXT1(10),
TEXT3 LIKE TEXT1 VALUE 'Initial'.
IMPORT TEXT3 FROM MEMORY ID 'text'.
WRITE: / SY-SUBRC, TEXT3.
IMPORT TEXT2 TO TEXT1 FROM MEMORY ID 'text'.
WRITE: / SY-SUBRC, TEXT1.
Example for SAPMZTS3:
PROGRAM SAPMZTS3.
DATA JTAB LIKE SBOOK OCCURS 10 WITH HEADER LINE.
IMPORT ITAB TO JTAB FROM MEMORY ID 'table'.
LOOP AT JTAB.
WRITE / JTAB-BOOKID.
ENDLOOP.
The output is displayed on two successive screens. It looks like this:
and
The program SAPMZTS2 attempts to read a data object TEXT3 from the data cluster "text", which does not exist. TEXT3 therefore remains unchanged. The existing data object TEXT2 is placed in TEXT1. In both cases, SY-SUBRC is 0, since the cluster "text" contains data.
The program SAPMZTS3 reads the internal table ITAB from the cluster "table" into the internal table JTAB. Both tables have the same structure, namely that of the ABAP Dictionary table SBOOK.

How to pass data between views using Flex for mobile?

Hi,
In my 1st view, I have set of images. Each image represents a product category. When I click on an image, it has to show my 2nd view which is a list. This should show all the products linked to this category.
I saw few examples where the 1st view is a list. Select an item in a list shows the details in the next view.
But what I need is, I need to know which image is clicked in my 1st view (ie) Home page. This id needs to be passed to my 2nd view to retrieve the data for the clicked image (clicked product category).
Can anyone help me in this?

Chellaa2011,
If I understand you correctly, you can pass data to the next view by passing the second parameter to the pushView method.
check out: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/spark/components/ViewNa vigator.html#pushView()
I've written similar apps in the past and found that a singleton class alleviates some of these issues. If you use a singleton to track currently selections all your views can access the same data without having to pass and return data from each other.
Hope this helps,
KLee

How To Pass Data Between A Main Report and a Subreport

Hello,
I'm working with Crystal Reports Professional XI.
I have a main report with two date parameters: BeginDate of Date type and EndDate of Data type. The main report has no details being printed instead it's grouped by a formula field and displays a summary count at the group footer. I have a subreport that is not linkable to the main report. The subreport is grouped differently. It has no detail records being printed and displays a summary count at the group footer as well. The two reports are using the same tables with the same linking relationship.
   I created the same two date parameters in the subreport but this isn't right because when I run the report then I get four Date prompts: BeginDate and EndDate parameter from the main report and the BeginDate and EndDate parameter from the subreport.
I'm not dong something right here. What do I need to change in the reports so that l have the same record selecton being passed from the main report to the subreport record selection based on the BeginDate parameter and the End Date parameter from the main report? Right now, the subreport is selecting all the records in the tables specified.
Have a great day. Any feedback would be greatly appreciated.
Thanks,
Ting

Hi Jason,
   Thanks for replying to my posting. It's been awhile since I've worked on Crystal Reports so I'm getting reacquainted with sub-reports again.
    By linking the main report to the subreport by the BeginDate and BeginEnd parameters, will the date parameters be passed from the main report to the record selection for the subreport?
   Also by doing your approach when the user is prompted to run the report, will it display on the popup window four date parameters: the BeginDate and EndDate from the main report and underneath that the BeginDate and EndDate from the sub report? If so I'm trying to avoid that because it would be the same date range that I'm wanting to use for the main report and the subreport.
    I hope that made sense.
Thanks,
Ting

How to transfer data between different tables in an Oracle 10g databse?

I have to do the following: there are 5 database tables in our Oracle 10g database that store certain data. Then there are 2 new tables where we want the data to go to. My task is to somehow transfer all the data that is in the first 5 tables and insert it in the 2 new ones. All tables are in the same database. The challenge lies in the fact that the structures of the tables are very dissimilar so it won't be a matter of a simple INSERT SQL query.
The data access tier of our application is developed in JAVA. We use EJB. So one way I am thinking of doing the above mentioned data transfer is to simply code it in the JAVA backed. But that might be to slow, there are millions of records in those first 5 tables. What is the best way to do something like that? Perhaps a custom (Perl?) script or some such?
Thanks.

The problem is that the way the data is stored in the old tables you cannot write a query that would return it in such a format that you could immediately insert it in the new table without some formatting. Let me illustrate with an example. To pull the data from the old tables I use this query:
SELECT
     SXML_DOCUMENT_DATA.VALUE As DocumentValue,
SXML_ELEMENT.NAME As ElementName
FROM
     SXML_DOCUMENT,
     SXML_DOCUMENT_DATA,
     SXML_DOCUMENT_DETAIL,
     SXML_ELEMENT,
     SXML_TYPE
WHERE
     SXML_TYPE.XML_TYPE_KEY = SXML_DOCUMENT.XML_TYPE_KEY
AND     SXML_DOCUMENT.XML_DOCUMENT_KEY = SXML_DOCUMENT_DETAIL.XML_DOCUMENT_KEY
AND     SXML_DOCUMENT_DETAIL.XML_DOCUMENT_DETAIL_KEY = SXML_DOCUMENT_DATA.XML_DOCUMENT_DETAIL_KEY
AND     SXML_ELEMENT.XML_ELEMENT_KEY = SXML_DOCUMENT_DATA.XML_ELEMENT_KEY
AND     SXML_TYPE.NAME = 'DA_UNIT_COMMITMENT'
AND     (SXML_ELEMENT.NAME = 'resource'
     OR SXML_ELEMENT.NAME = 'resourceType'
     OR SXML_ELEMENT.NAME = 'commitmentType'
     OR SXML_ELEMENT.NAME = 'startTime'
     OR SXML_ELEMENT.NAME = 'endTime'
     OR SXML_ELEMENT.NAME = 'schedulingCoordinator')
ORDER BY
     SXML_DOCUMENT.NAME,
     SXML_DOCUMENT_DETAIL.XML_DOCUMENT_DETAIL_KEY,
     SXML_DOCUMENT_DATA.XML_DOCUMENT_DATA_KEY,
     SXML_ELEMENT.NAME;
The results from the SQL query above look like this:
DOCUMENTVALUE | ELEMENTNAME
1 | ALAMIT_7_UNIT_1 | resource
2 | GEN | resourceType
3 | BRS8 | schedulingCoordinator
4 | IFM | commitmentType
5 | 2008-07-29T18:00:00:00 | startTime
6 | 2008-07-30T00:00:00 | endTime
7 | ALAMIT_7_UNIT_1 | resource
8 | GEN | resourceType
9 | BRS8 | schedulingCoordinator
10 | IFM | commitmentType
11 | 2008-07-29T00:00:00 | startTime
12 | 2008-07-29T04:00:00 | endTime
and so on. The type of data repeats every 6 records. And the values of each 6 records corresponds to 1 row in the new table, which looks like this:
schedulingCoordinator | resource | resourceType | commitmentType | startDate | endDate
1| 1 | 27 | GEN | IFM | 2008-07-29T18:00:00:00 | 2008-07-30T00:00:00
2| 1 | 27 | GEN | | 2008-07-29T00:00:00 | 2008-07-29T04:00:00
So hopefully now you see the challenge. It is not as simple as writing a SQL query that returns result rows corresponding 1 to 1 to a row in the new table. Somehow I need to take the first 6 result rows from that big SQL query and put them in the first row of the new table. Then the next 6 and put them in the second row and so on. And also, we are talking about millions of records. What happens if I process the first 2 million and then some error occurs? Do I start from the beginning again? One idea I have is to process the data in chunks, say process 500 results, commit, process another 500, commit, and so on.

How to pass data from report list to program?

Hi all,
I have displayed an internal table content in a list with some fields setting input on.
For example,
LOOP AT ITAB.
   WRITE: ITAB-MATNR.
   WRITE: ITAB-MAKTX INPUT ON.
   WRITE: ITAB-LABOR INPUT ON.
ENDLOOP
Suppose there are 4 entries in ITAB, user then changes the MAKTX, LABOR of any 3 entries.
Now, I want to update ALL the fields values (MAKTX, LABOR) on the list to database even though some fields values have not been changed. How could I pass ALL the fields values (MAKTX, LABOR) from the screen to the program? Should I use the read line command?
Please help. Thanks.

It's been a while since I tried this, but I think it goes:
do:
READ LINE sy-index FIELD VALUE ITAB-MATNR INTO matnr.
if sy0subrc <> 0.
    exit.
endif.
enddo.
The ABAP know that you wrote itab-matnr, and READ LINE is able to get that variable back again.

Best method for passing data between nested components

I have a fairly good sized Flex application (if it was
stuffed all into one file--which it used to be--it would be about
3-4k lines of code). I have since started breaking it up into
components and abstracting logic to make it easier to write,
manage, and develop.
The biggest thing that I'm running into is figuring out a way
to pass data between components. Now, I know how to write and use
custom events, so that you dispatch events up the chain of
components, but it seems like that only works one way (bottom-up).
I also know how to make public variables/functions inside the
component and then the caller can just assign that variable or call
that function.
Let's say that I have the following chain of components:
Component A
--Component B
-- -- Component C
-- -- -- Component D
What is the best way to pass data between A and D (in both
directions)?
If I use an event to pass from D to A, it seems as though I
have to write event code in each of the components and do the
bubbling up manually. What I'm really stuck on though, is how to
get data from A to D.
I have a remote object in Component A that goes out and gets
some data from the server, and most all of the other components all
rely on whatever was returned -- so what is the best way to be able
to "share" data between all components? I don't want to have to
pass a variable through B and C just so that D can get it, but I
also don't want to make D go and request the information itself. B
and C might not need the data, so it seems stupid to have to make
it be aware of it.
Any ideas? I hope that my explanation is clear enough...
Thanks.
-Jake

Peter (or anyone else)...
To take this example to the next (albeit parallel) level, how
would you go about creating a class that will let you just
capture/dispatch local data changes? Following along my original
example (Components A-D),let's say that we have this component
architecture:
Component A
--Component B
-- -- Component C
-- -- -- Component D
-- -- Component E
-- -- Comonnent F
How would we go about creating a dispatch scheme for getting
data between Component C and E/F? Maybe in Component C the user
picks a username from a combo box. That selection will drive some
changes in Component E (like triggering a new screen to appear
based on the user). There are no remote methods at play with this
example, just a simple update of a username that's all contained
within the Flex app.
I tried mimicking the technique that we used for the
RemoteObject methods, but things are a bit different this time
around because we're not making a trip to the server. I just want
to be able to register Component E to listen for an event that
would indicate that some data has changed.
Now, once again, I know that I can bubble that information up
to A and then back down to E, but that's sloppy... There has to be
a similar approach to broadcasting events across the entire
application, right?
Here's what I started to come up with so far:
[Event(name="selectUsername", type="CustomEvent")]
public class LocalData extends EventDispatcher
private static var _self:LocalData;
// Constructor
public function LocalData() {
// ?? does anything go here ??
// Returns the singleton instance of this class.
public static function getInstance():LocalData {
if( _self == null ) {
_self = new LocalData();
return _self;
// public method that can be called to dispatch the event.
public static function selectUsername(userObj:Object):void {
dispatchEvent(new CustomEvent(userObj, "selectUsername"));
Then, in the component that wants to dispatch the event, we
do this:
LocalData.selectUsername([some object]);
And in the component that wants to listen for the event:
LocalData.getInstance().addEventListener("selectUsername",
selectUsername_Result);
public function selectUsername_Result(e:CustomEvent):void {
// handle results here
The problem with this is that when I go to compile it, it
doesn't like my use of "dispatchEvent" inside that public static
method. Tells me, "Call to possibly undefined method
"dispatchEvent". Huh? Why would it be undefined?
Does it make sense with where I'm going?
Any help is greatly appreciated.
Thanks!

How to pass data from one internal session to another

Memory Structures of an ABAP Program
In the Overview of the R/3 Basis System you have seen that each user can open up to six R/3 windows in a single SAPgui session. Each of these windows corresponds to a session on the application server with its own area of shared memory.
The first application program that you start in a session opens an internal session within the main session. The internal session has a memory area that contains the ABAP program and its associated data. When the program calls external routines (methods, subroutines or function modules) their main program and working data are also loaded into the memory area of the internal session.
Only one internal session is ever active. If the active application program calls a further application program, the system opens another internal session. Here, there are two possible cases: If the second program does not return control to the calling program when it has finished running, the called program replaces the calling program in the internal session. The contents of the memory of the calling program are deleted. If the second program does return control to the calling program when it has finished running, the session of the called program is not deleted. Instead, it becomes inactive, and its memory contents are placed on a stack.
The memory area of each session contains an area called ABAP memory. ABAP memory is available to all internal sessions. ABAP programs can use the EXPORT and IMPORT statements to access it. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
All ABAP programs can also access the SAP memory. This is a memory area to which all sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters are often used to preassign values to input fields. You can set them individually for users, or globally according to the flow of an application program. SAP memory is the only connection between the different sessions within a SAPgui.
The following diagram shows how an application program accesses the different areas within shared memory:
In the diagram, an ABAP program is active in the second internal session of the first main session. It can access the memory of its own internal session, ABAP memory and SAP memory. The program in the first internal session has called the program which is currently active, and its own data is currently inactive on the stack. If the program currently active calls another program but will itself carry on once that program has finished running, the new program will be activated in a third internal session.
Data Clusters in ABAP Memory
You can store data clusters in ABAP memory. ABAP memory is a memory area within the internal session (roll area) of an ABAP program and any other program called from it using CALL TRANSACTION or SUBMIT.
ABAP memory is independent of the ABAP program or program module from which it was generated. In other words, an object saved in ABAP memory can be read from any other ABAP program in the same call chain. ABAP memory is not the same as the cross-transaction global SAP memory. For further information, refer to Passing Data Between Programs.
This allows you to pass data from one module to another over several levels of the program hierarchy. For example, you can pass data
From an executable program (report) to another executable program called using SUBMIT.
From a transaction to an executable program (report).
Between dialog modules.
From a program to a function module.
and so on.
The contents of the memory are released when you leave the transaction.
To save data objects in ABAP memory, use the statement EXPORT TO MEMORY.
Saving Data Objects in Memory
To read data objects from memory, use the statement IMPORT FROM MEMORY.
Reading Data Objects from Memory
To delete data clusters from memory, use the statement FREE MEMORY.
Deleting Data Clusters from Memory

How to pass data from one session to another?

What does SAP memory use to pass data between sessions?
What is the syntax of "Export to ..."? Where is it used?

hi suman vijay,
EXPORT obj1 ... objn TO MEMORY.
Exports the objects obj1 ... objn (fields, structures or tables) as a data
cluster to ABAP/4 memory .
EXPORT obj1 ... objn TO DATABASE dbtab(ar) ID key. Exports the objects obj1 ... objn (fields, structures or tables) as a data cluster to the database table dbtab.
IMPORT f itab FROM MEMORY.
Imports data objects (fields or tables) from the ABAP/4 memory . Reads in all data without an ID that was exported to memory with "EXPORT ... TO MEMORY."
IMPORT f itab FROM DATABASE dbtab(ar) ID key. imports data objects (fields, field strings or internal tables) with the ID key from the area ar of the database dbtab .
EXPORT obj1 ... objn TO MEMORY.
If you call a transaction, report or dialog module (with CALL TRANSACTION , SUBMIT or CALL DIALOG ), the contents of ABAP/4 memory are retained, even across several levels. The called transaction can then retrieve the data from there using IMPORT ... FROM MEMORY .
Each new EXPORT ... TO MEMORY statement overwrites any old data, so no data is appended.
EXPORT obj1 ... objn TO DATABASE dbtab(ar) ID key
The database table dbtab must have a standardized structure .
The database table dbtab is divided into different logically related areas ( ar , 2-character name).
You can export collections of data objects (known as data clusters ) under a freely definable key (field key ) to an area of this database.
IMPORT allows you to import individual data objects from this cluster.
thanks

Pass data between InfoPath forms in SharePoint

Hello!
Maybe someone has ideas about the next issue: how to make pass data between InfoPath forms in SharePoint, like it is shown in a video: https://www.youtube.com/watch?v=-nGl-Se2cOQ
I've read similar topics, but still can't find solution.
Thank you.

When you go to modify the submit connection, you can specify whether or not to overwrite, as well as a default title value. If you use the now() function in the title, it should never have the same name.

How to Reconcile Data Between SAP Source Systems and SAP NetWeaver BI

Hi,
I just read "How to Reconcile Data Between SAP Source Systems and SAP NetWeaver BI". While I'm waiting for more authorisation to r/3 to carry it out and test this functionality.
I'd like to ask a question to anyone who has implemented this type solution. On page 10 it talks about creating a view then setting up the datasource. The solution talks about runnig a query. I suspect when we run a query I would run it for only a period(using variable) to reconcile.
My question is this. Will the datasource extractor on /r3 only select the period in our variable or will it do a full selection of the data which would then be passed to BW for filtering?
Regards

DEar Mark,
There are several avenues where you can see and reconcile your data with source system, u can see data in by tcode RSA3 for a datasource, and compare the values with actual document posted into the R/3 system. Respective fuctional consultant canhelp you a lot to confirm the data.
On BW side u can see the data in PSA and then check tranformations which subsequent change/update/reject data records based on the selective conditions.
hope this helps.
Kindly assign the points if it works.
Revert back if u need futher help/information.
