No of minuts in McuJoinsAndLeaves and session tables ????
Hi All,
I am trying to find out the No. of minutes in McuJoinsAndLeaves table(lcscdr DB) and session table(Qoeetrics DB) are exactly same or not..?? if no. of minutes are same in both table............please tell me conditions ????
Thanks
Brij
Which column did you refer to?
Please compare these two tables according to the following link.

What is the meaning of "PSEUDO" and "NONE" in v$session table.
Hi
What is the meaning of "PSEUDO" and "NONE" in v$session table.
V$SESSION:
SERVER VARCHAR2(9) Server type (DEDICATED| SHARED| PSEUDO| NONE)
thanks
sivaPSEUDO is the server column's value of killed sessions, until they are cleaned up by PMON.
A dedicated server session will always have DEDICATED as server value, while a shared server session has SHARED when it's active, and NONE when it's inactive. -
Hi friends,
In oracle EBS R12.1.3 we have two language preference options like 'AR' for Arabic and 'US' for English. Soon after the user changes the respective language and logs into the EBS application, those change languages will be stored as a code in session table for that EBS user.
I need to know that session table name where does the language is get setted for the user who logs into the application, so that i can query the appropriate session language for the corresponding user from the table in db.
Thanks in advance.

Hi Srini,
Actually the problem that im facing is that i couldnt pass the USERENV('LANG') variable to the where clause in my APEX from EBS session.
I have APEX 4.2 integrated with Oracle EBS R12.1.3, now from the EBS menu i can redirect to the apex page(by passing the apex login page) with EBS credentials.
Im near to the stage of bringing Arabic and English language in APEX, as my db contains data in both the lang.
But I need to bring it according to the USERENV(‘LANG’) that is set in the db for the users session from EBS login. But if I used the USERENV(‘LANG’) parameter in APEX it is not recognizing this EBS user language parameter. Whether you have any idea of how to make the APEX to recognize this EBS user language parameters.
I dont know how to pass this EBS user session variable to the apex, so that the data will be visible according to the EBS session language they select(either 'AR' or 'US').
If i give like below in the APEX report query of my where clause, means
where language = userenv('lang')
It is not working. But if i harcode like
where language = 'AR' means then i can see the arabic datas from db in APEX, but how i can pass this userenv code dynamically according to the EBS logged in user to the APEX.
Thanks
Brgds,
MiniThis is a different topic and I see that you have created another thread for it -- How to pass userenv('lang') of EBS user session to APEX 4.2 pages

Upload file with iframe loos session user and session id in wwv_flow_files
Hello every one, hope someone could help us with this problem.
What we are trying to do is to upload a file from a jquery dialog in a appex page by redirecting the POST action of the wwvFlowForm to the iframe.
*1. In the javascript there is the function call to open my modal window with the input*
function add_fichier_form(numeroProjet,idCat){
$("#div_upload_fichier").dialog(
modal : true ,
autoOpen : false ,
resizable: false ,
width: 700
$('#div_upload_fichier').parent().appendTo('#div_base');
$('#upload_button').unbind('click').click(function(){
if ($('#P4010_FILE_FICHIER').val() != '') {
$('#upload_iframe_v2').unbind('load').load(function () {
$('#upload_status').html(' déplacement du fichier...');
// move the file
$('#upload_status').html('Fichier transféré avec succès');
//file transfer ok
//calling the javascript function to add everything in my own table;
//we see the file in the wwv_flow_file_objects$ without
add_fichier_form_db();
// set the form target to the iframe, submit, then remove the target
$('#wwvFlowForm').attr('target','upload_iframe_v2').submit().removeAttr('target');
$('#upload_status').html(' Téléchargement du fichier...');
}else {
alert('Veuillez sélectionner un fichier');
$("#div_upload_fichier").dialog("option", "title", "Ajout d'un fichier");
$("#div_upload_fichier").dialog("open");
}*2. At this point we see the file in the table but without the user and session credential*
select *
from wwv_flow_file_objects$
The result is that the field security_group_id is assign to 0 AND created_by = APEX_PUBLIC_USER
*3. add_fichier_form_db(); the javascript function making the ajax call to a procedure plsql*
function add_fichier_form_db(){
//alert ('Dasn fichier form db');

jocelynFinally we find what was wrong so i give you the solution.
In the javascript on the function add_fichier_form
We need to append the div of the form to the default form of apex wwvFlowForm
so the line*
$('#div_upload_fichier').parent().appendTo('#div_base');
should be change to*
$('#div_upload_fichier').parent().appendTo('#wwvFlowForm');Edited by: jocbed on 2012-01-26 11:08 -
Code and core tables in different schemas
Hi,
My db version : Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
I would like to understand, the pros and cons of the following situation:
We have a single application.
The db design for this application has 44 tables out of which 28 are core tables related by PK and FK relationships. The remaining 16 are look up and reference tables which are not related to any.
The team decided to place the 28 core tables in one schema A and the remaining 16 in another schema B within same database. (The reason for this is..since it is done in other projects lets do it here too).
Now comming to the code (stored procs, functions, packages etc). The teams wants to place most of the code in the schema B that has the 16 ref tables. (the reason again being the same).
What are the pros and cons doing this???
Please advice.
PS:
I have googled and found sth on these lines:
cons:
o harder to manage
o harder to upgrade
o harder to patch
o harder to maintain
o causes your shared pool size to increase 1,000 times (shared sql goes down the tubes)
o takes more space
o queries against the dictionary will be impacted
o latching on the shared pool goes WAY up (latching = locks = serialization device =
slows you down)
pros:
o none that I can think of.>
I would like to understand, the pros and cons of the following situation:
Yes I am straining to find more points (was not good at it though).

You just want to understand? Are you sure? Your thread reads more like you just want to do things your way and are looking for support.

My question to you is: what PROBLEM are you trying to solve? If the 'team' already uses this approach and there haven't been any substantive problems then why try to change things now? Why have you chosen to fight this battle?
Your 'team' has already decided and now, after that decision, you want to argue about it with them? The time to present arguments for/against a given plan is BEFORE the decisions are made, not after. Once a decision is made you need to be a team player and implement that decision to the best of your ability.
One thing I'm certain of. If you try to support your argument using things like that 'AskTom' link you posted any credibility you had will go out the window. That link, as you already hinted yourself, is not your use case at all. All it takes is for one of your 'team' members to point that out and everyone will pretty much stop listening to any other arguments you make.
People are generally not going to 'change their ways' unless you can show them:
a) there is something seriously wrong with the way they are now doing things or
b) a new way of doing things provides some substantial benefits
Choice 'a' above is where you need to start but you haven't provided ANY information in this post that you have identified any serious issues with the status quo.
The main task for Oracle is to be able to FIND the objects being referenced. So, in my opinion, that is what you should focus on when looking for PRO/CON arguments.
That is: What issues are there if an object being referenced is in a different schema than the session that needs to use the object?
1. objects may need to be prefixed with the schema name
2. public or private synonyms may need to be created/maintained to avoid having to deal with item #1 above
3. new grants may be needed to implement/maintain the proper security
4. new roles may need to be created to maintain proper security (see item #3 above)
5. additional work will be needed to maintain the new roles in item #4 above
6. PL/SQL code may not be able to reference the object or may reference the wrong object
7. Roles are disabled in PL/SQL (see item #6 above) - this means that the new grants (see item #3) may need to be granted directly to the schema users that need access instead of to roles. That can make it harder to create and maintain a role-base security schema.
If I were you I would spend my time on other more important thingsd. But if I chose to fight this particular battle then I would make a list of problems that occured in the past with the current method of doing things and also problems related to the above list of items and then show how many of those problems will 'disappear' if the new method is used. -
Hi,
Archiving Database Schema states that in the tables SessionDetails and Conferences tables, the column 'SessionIdTime'
holds datetime value at which session request is captured by Archiving service.
But, is there any order in which the records are stored in the db?
Say, a session 'S1' starts at 1:00 PM and another session 'S2' starts at 1:05PM. 'S2' ends at 1:10 PM and 'S1' is still on going. I have observed that on ending the session the record is written to DB, so is it possible that details of session S2 is written
in db prior to 'S1'?
Is there any way to query these tables, in the order in which the records are stored?
Thanks and Regards,
ArjabhHi,
You can export records that have been stored in the Lync Server Archiving database with the following cmdlet in the link using Lync server manageshell.
http://technet.microsoft.com/en-us/library/gg398452.aspx
You need to write a SQL query/view or report server report to display the information.
More details:
http://blogs.technet.com/b/dodeitte/archive/2013/06/02/sample-lync-server-archiving-report-available.aspx
For the issue about “is there any order in which the records are stored in the db?” you can post a case to SQL forum and more experts will help to verify the issue.

How to use Connection.clientinfo with v$session table
Hi everyone,
I'm trying to keep tabs on the number of connections I create (via python and cx_Oracle) by monitoring Oracle's v$session table.
From the cx_Oracle docs, it appears the preferred way to write my "module" and "action" parameters to v$session is via the Connection.clientinfo method.
I tried creating a connection and using that method, but the results did not appear in the v$session table. Below is how I called the method:
cnx.clientinfo(module="name of module", action="myaction")
Is that the correct way to use "clientinfo"?
The cx_Oracle docs don't provide any usage examples (that I could find), and only point to the Python DB API specs. I didn't notice a mention of this method there:
http://www.python.org/dev/peps/pep-0249/
Can anyway show me an example of how to use the "clientinfo" method? Also, is it necessary to have "write" permission for my username in order to access v$session? If so, perhaps that's my problem...C:\Documents and Settings\tchsensoy>python

Business Delegate and Session Facade usage.
Hi guys.
I am new to JavaEE and I recently learnt the Business Delegate and Session Facade design patterns. The tutorials from Oracle did gave me a basic idea of what they are and why they are used, but the example didn't really answer all my questions. So I decided to use a real life scenario here and put my question in to it. Any help is appreciated.
Assume I want to create a search employee page for my company, the employees are categorized by his or her department and the province he or she is in. I have in the database a look up table for department and province. (as shown in the image below)
http://oi46.tinypic.com/idvpsl.jpg
So I create three JPA entities, one for each table. Now I am stuck with what is the proper way to design the session facade design pattern. I know that I will need the to access all three entities in my page. (to get the drop down list for Provinces and Departments, and to retrieve list of Employees based on the selection) So should I create a Stateless Session Bean as session facade to access all three JPA Entities or should I create three separate Stateless Session Bean to manage one Entity each?
I came up three component diagram in the below picture.
The first one has one Stateless Session Bean as session facade and manages all three Entities.
The second one has a session facade to manage the relationship between business objects such as ProvinceManagerEJB and DepartmentManagerEJB which will manage the corresponding Entities.
The last one has three Stateless Session Beans that will manage one Entity each, all three Stateless Session Beans can be looked up via the Business Delegate pattern.
http://oi46.tinypic.com/10pqets.jpg
Please let me know if any one of them is the proper way to use business delegate and session facade. or none of them is correct. (which I assume might happen)
Again, thank you so much for your help.
Cheers

Edited by: 992005 on 05-Mar-2013 18:17Well I can't access any of your diagrams from here so can't comment on them. For dividing the functionality into separate classes, think about
1.) Quantity - Are there many enough service calls to require splitting up or will one application service class be enough? The size of the system is important here.
2.) Are you duplicating logic in the services? e.g save person, delete person in one service and save department, delete department in another e.t.c is better factored into one service with save entity, delete entity calls because the JPA entity manager doesn't know about the type anyway and it's easier to apply common logic (e.g logging auditing) around the calls.
3.) Will each service makes sense on it's own or do you always need the other functionality to completely describe the service? Here it is important not think about entities but about the business use cases. Process1Service is better than Entity1Service, Entity2Service ... EntitynService.Think granule of reuse = granule of release. Only split out individually reusable services. A good way to understand granules of reuse in your system is to think about (or start by writing) test cases for the functionality. Testable code is reusable code.
4.) Will the services change together? At class level you would look at common closure principle (classes that change together should be packaged together). You can apply the closure to the methods as well. Make it easy for future developers to recognize dependent functionality by packaging it together.
These are just general because in enterprise development requirements are king. You can chose to follow or discard any of these rules depending on your requirements as long you understand the impact of each decision. -
COMMAND column in V$SESSION table
Is there any table which stores all the meaning of various values that can be stored in COMMAND column of V$SESSION table
Like 3 is for SELECT and 47 for Execute, I found some documentation in data dictionary but was wondering if there is some table that can be used when a trigger or procedure is running to pull the values on the fly.
ThxYou can find the various values for V$SESSION.COMMAND in Table 7-5 COMMAND Column of V$SESSION and Corresponding Commands found in the link below to build your own table.

Identifying deadlocked resources in graph with 1 row lock and 1 table lock
Hi, I have run into repeated occurrences of the deadlock graph at the bottom of this post and have a few questions about it:
1. It appears that proc 44, session 548 is holding a row lock (X). Is the waiter, proc 30, session 542, trying to acquire a row lock (X) also or an exclusive table lock (X) on the table containing that row?
2. Under what circumstances would something hold a row exclusive table lock (SX) and want to upgrade that to a share row exclusive table lock (SSX)?
3. Our table cxml_foldercontent has a column 'structuredDataId' with a FK to cxml_structureddata.id and an ON DELETE SET NULL trigger. Would this help explain why an "update" to one table (i.e.g cxml_foldercontent) would also need to acquire a lock in a foreign table, cxml_structureddata?
4. What is the difference between "Current SQL statement:" and "Current SQL statement for this session:"? That terminology is confusing. Is session 542 executing the "update" or the "delete"?
5. In the "Rows waited on:" section is it saying that Session 542 is waiting on on obj - rowid = 0000BE63 - AAAL5jAAGAAA6tZAAK or that it is has the lock on that row and other things are waiting on it?
A couple of notes:
- the cxml_foldercontent.structuredDataId FK column has an index on it already

delete from cascade.cxml_structureddata where id=:1Mohamed Houri wrote:
What is important for a foreign key is to be indexed (of course if the parent table is deleted/merged/updated, or if a performance reason imposes it). Wether this index is unique or not doesn't matter (as far as i know).But, you should ask your self the following question : what is the meaning of having a 1 to 1 relationship between a parent and a child table ? if you succeed to create a unique index on your FK then this means that for each PK value corresponds at most one FK value!! Isn't it? is this what you want to have?Thanks, as I mentioned above, cxml_structureddata is actually the child table of cxml_foldercontent with 1 or more records' owningEntityId referring to rows in cxml_foldercontent. The reason for the FK on cxml_foldercontent.structuredDataId is a little ambiguous but it explained above.
Will a TX-enqueue held on mode X always be waited on by another TX-enqueue row lock X? Or can it be waited on by an Exclusive (X) table lock?Not really clear. Sorry, are you saying my question is unclear or it's not clear why type of eXclusive lock session 542 is trying to acquire in the first line of the trace? Do you think that the exclusive lock being held by session 548 in the first line is on rows in cxml_foldercontent (due to the ON DELETE SET NULL on these child rows) or rows in the cxml_structureddata that it's actually deleting?
Is there any way for me to tell for certain?
The first enqueue is a TX (Transaction Enqueue) held by session 548 on mode X (exclusive). This session represents the blocking session. At the same time the locked row is waited on by the blocked session (542) and the wait is on mode X (exclusive). So put it simply, we have here session 542 waiting for session 548 to release it lock (may be by commiting/roll backing). At this step we are not in presence of a deadlock.
The second line of the deadlock graph shows that session 542 is the blocking session and it is doing a TM enqueue (DML lock) held on SX(Shared eXclusive). While session 548(which is the waiting session) is blocked by session 542 and is waiting on SSX mode.
Here we see that 548 is blocking session 542 via a TX enqueue and session 542 is blocking session 548 via a TM enqueue ---> That is the deadlock. Oracle will then immediately choose arbitrarlly a victim session (542 or 548) and kill its process letting the remaining session continuing its work.
That is your situation explained here.Thanks, any idea why session 542 (the DELETE from cxml_structureddata) would be trying to upgrade it's lock to SSX? Is this lock mode required to update a child tables foreign key columns when using an ON DELETE SET NULL trigger? Having read more about SSX, I'm not sure I understand in what cases it's used. Is there a way for me to confirm with 100% certainty specifically which tables in the TM enqueue locks are being held on? Is session 548 definitely trying to acquire an SSX mode on my cxml_foldecontent table or could it be cxml_structureddata table?
(a) Verify that all your FK are indexed (be carreful that the FK columns should be at the leading edge of the index)Thanks, we've done this already. When you say the "leading edge" you mean for a composite index? These indexes are all single column.
(b) Verify the logic of the DML against cxml_foldercontentCan you be more specific? Any idea what I'm looking for? -
What is the diffreence between call transaction and session method
hi gurus
can any one suggest me
what is the difference between call transaction and session methods
in which cases we have to use teh call transaction and
in which cases we have to use session method.
thank you
regards
kals.CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
BATCH INPUT METHOD:
This method is also called as ‘CLASSICAL METHOD’.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
Features:
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.
http://www.sap-img.com/abap/difference-between-batch-input-and-call-transaction-in-bdc.htm
Among the two methods call transaction is better compared to session bcoz data transfer is faster in it.
Differences between call transaction and session.
Session Method:
1) Data is not updated in the database table until the session is processed.
2) No sy-subrc is returned.
3) Error log is created for error records.
4) Updation is always synchronous.
Call Transaction Method:
1) Immediate updation in the database table.
2) sy-subrc is returned.
3)Error need to be handled explicitly.
4) updation can be synchronous as well as asynchronous.
2) ya u can use using the N mode no screen.
3)u can't handle multiple transaction in call transaction.
4) u can handle multiple transaction in session using the BDC_INSERT fm.
5)When u go to SM35 u can able to see the error records.
Which is best?
That depends on your requirement. Both of them have there advantages.
According to the situation u can choose any one of these.
difference between batch input and call transaction in BDC Session method.
1) synchronous processing.
2) can tranfer large amount of data.
3) processing is slower.
4) error log is created
5) data is not updated until session is processed.
Call transaction.
1) asynchronous processing
2) can transfer small amount of data
3) processing is faster.
4) errors need to be handled explicitly
5) data is updated automatically
For session method,these are the function modules to b used.
BDC_OPEN_GROUP
BDC_INSERT
BDC_CLOSE_GROUP
For call transaction,this is the syntax.
CALL TRANSACTION TCODE USING BDCDATA
MODE A or E or N
UPDATE A or S

Take a scenario where we need to post documents in FB01 and the input file has say 2000 records (2000 documents, not line items in FB01 but 2000 records)
In the BDC call transaction method
We call the transaction FB01 2000 times (once for each record posting) and if the processing fails in record no 3 it can be captured and start with reocord 4.
Eg: Loop at itab.
call transaction FB01
capture errors
endloop.
In the session method.
We do not explicity call the transaction 2000 times, but all the records are appeneded into a session and this session is stored. The processinf of the session is done wwhenever the user wants it to be done. Hence the errors cannot be captured in the program itself

Batch Input Session method is asynchronous as told by others here. But the advantage of this is that you have all the error messages and the data for each transaction held persistantly. You don't have to code anything for processing them or writing the logs.
But at the same time, the same feature can be disadvantageous if you need to react to an error or if there are too many errors to manually correct in a session. Since the session are created in the program and its execution is done seperately, you loose the trackability of such transactions.
With a call transaction, what was a disadvantage above will become an advantage. Call transaction immediately gives you messages back and you can react to it in your program. But the disadvantage is that, if you have several hundreds of transactions to run, running them from within the program can be resource crunching affair. It will hamper the system performance and you cannot really distribute the load. Of course, you have some mechanisms with which you can overcome this, but you will have to code for it. Also, storing the messages and storing the errored transaction data etc will have to be handled by you in the program. Whereas, in batch input session, your program's job is to just create the session, after that everything is standard SAP system's responsibility.
Ideally, you should do a call transaction if the resources are not a problem and if it fails, put the errored transaction into a session.
You can decide based on the data volume that your BDC is processing. If data volume is high go for session else call transaction will do.The call transaction updates will be instantaneous where as session needs to be processed explictly after creation.
Session Method
1) Session method supports both small amount of data aswell as large amount of data
2) data processing is asynchronus and data updation is synchronus.
3) it process multiple apllication while perfomaning validations.
4) in session method data will be updated in data base only after processing session only.
5) system provide by default logfile for handling error records.
6) it supports both foreground aswell as background process
in bdc we use FM ...
bdc_open_group " for creating Session
bdc_insert " adding transaction and bdcdata table for updating database
bdc_close_group " for closing Session
Call Transaction
1) Call transaction exclusively for small amout of data
2) it supports only one apllication while perfoming validations
3) there is no default logfile, We can explicitly provide logic for creating logfile for handling error records.
we can create logfile by using structure....BDCMSGCOLL
4) it doesn't support background processing.
5) data processing is synchronous and Data updation is Synchronous( default), in
this method also supports daya updation in asynchronus process also.
syntax:
Call transaction <transaction-name> using BDCDATA
mode <A/N/E>
update <L/A/S>
messages into BDCMSGCOLL.
BDC:
Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
Features :
BDC is an automatic procedure.
This method is used to transfer large amount of data that is available in electronic medium.
BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
BDC uses normal transaction codes to transfer data.
Types of BDC :
CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
BATCH INPUT METHOD:
This method is also called as ‘CLASSICAL METHOD’.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
Features:
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.

Dif betwen BDC call transaction and session method
Hi to all,
This is my problem. I want to know, what is the difference between BDC call Transaction method and Session method. where the situation we can use these methods.
I will be thankfull to all.Session Method :
Asynchronous Processing.
Transfers Data for Multiple Transactions
Synchronous Database Update
During Processing, No Transaction is started until the previous transction has been written to the database.
A Batch Input Processing log is generated for each session
Sessions can not be generated in Parallel.
The Batch Input Porgram must not open a Session until it has closed the preceding Session.
Call Transaction :
Synchronous Processing.
Transfers Data for a single transaction.
Synchronous and Asynchronous Database updating both Possible.
The Program Specifies which kind of updating is desired.
Seperate LUW for the transaction.
The System Performs a database commit immediately before and after the CALL TRANSACTION Using Statement.
No Batch Input Processing Log is generated.
These are the differences between session and call transaction method.
Call transaction is faster then session method. But usually we use session method in real time...because we can transfer large amount of data from internal table to database and if any errors in a session. Process will not complete until session get correct. -
Can we hav call transaction and session method for an application
can we hav call transaction and session method for an application ?if yes how?
Hi ,
You can. If Call Transaction fails, a batch input session can be created.
Check this example-
Call the transaction. Messages from Call Transaction are stored in the
internal table messtab
CALL TRANSACTION 'LT01' USING bdc_tab MODE 'N' UPDATE 'S'
MESSAGES INTO messtab.
IF sy-subrc = 0.
Call transaction successfull, get the number of the Transfer Order that
was created
LOOP AT messtab.
IF messtab-dynumb = '0104' AND messtab-msgnr = '016'.
w_transportorderno = messtab-msgv1.
ENDIF.
ENDLOOP.
ELSE.
Call transaction failed, create a batch input session instead.
PERFORM open_group.
PERFORM bdc_insert USING 'LT01'.
PERFORM close_group.
ENDIF.

Difference b/w call transaction and session method
hi there,
whatz the major difference b/w call transaction and session method in BDC.
thanks in advance
dattuVijay,
Welcome to SDN
<b>SESSION METHOD</b>
Data is not updated in database table unless Session is processed.
No sy-subrc is returned.
Error log is created for error records.
Updation in database table is always synchronous
<b>CALL TRANSACTION</b>
Immediate updation in database table.
Sy-subrc is returned.
Errors need to be handled explicitly
Updation in database table can be synchronous Or Asynchronous.

Regarding call transaction and session method???
HI All,
Cud u pls let me know
1. differences between call transaction and session???
2. Is it possible to schedule call transaction in background?? ( all are saying MODE N = background scheduling in call transaction.......but i dont think so)
3. Is it posible to handle multiple transactions in call transaction ? if so,how?
4. Is it posible to handle multiple transactions in session ? if so,how?
5. How can we see the log in session method????Hi ,
Check this documentation.
About Session method
In this method you transfer data from internal table to database table through sessions.
In this method, an ABAP/4 program reads the external data that is to be entered in the SAP System and stores the data in session. A session stores the actions that are required to enter your data using normal SAP transaction i.e., Data is transferred to session which in turn transfers data to database table.
Session is intermediate step between internal table and database table. Data along with its action is stored in session i.e., data for screen fields, to which screen it is passed, the program name behind it, and how the next screen is processed.
When the program has finished generating the session, you can run the session to execute the SAP transactions in it. You can either explicitly start and monitor a session or have the session run in the background processing system.
Unless session is processed, the data is not transferred to database table.
BDC_OPEN_GROUP
You create the session through program by BDC_OPEN_GROUP function.
Parameters to this function are:
User Name: User name
Group: Name of the session
Lock Date: The date on which you want to process the session.
Keep: This parameter is passed as X when you want to retain session after
processing it or to delete it after processing.
BDC_INSERT
This function creates the session & data is transferred to Session.
Parameters to this function are:
Tcode: Transaction Name
Dynprotab: BDC Data
BDC_CLOSE_GROUP
This function closes the BDC Group. No Parameters.
Some additional information for session processing
When the session is generated using the KEEP option within the BDC_OPEN_GROUP, the system always keeps the sessions in the queue, whether it has been processed successfully or not.
However, if the session is processed, you have to delete it manually. When session processing is completed successfully while KEEP option was not set, it will be removed automatically from the session queue. Log is not removed for that session.
If the batch-input session is terminated with errors, then it appears in the list of INCORRECT session and it can be processed again. To correct incorrect session, you can analyze the session. The Analysis function allows to determine which screen and value has produced the error. If you find small errors in data, you can correct them interactively, otherwise you need to modify batch input program, which has generated the session or many times even the data file.
CALL TRANSACTION
About CALL TRANSACTION
A technique similar to SESSION method, while batch input is a two-step procedure, Call Transaction does both steps online, one after the other. In this method, you call a transaction from your program by
Call transaction <tcode> using <BDCTAB>
Mode <A/N/E>
Update <S/A>
Messages into <MSGTAB>.
Parameter 1 is transaction code.
Parameter 2 is name of BDCTAB table.
Parameter 3 here you are specifying mode in which you execute transaction
A is all screen mode. All the screen of transaction are displayed.
N is no screen mode. No screen is displayed when you execute the transaction.
E is error screen. Only those screens are displayed wherein you have error record.
Parameter 4 here you are specifying update type by which database table is updated.
S is for Synchronous update in which if you change data of one table then all the related Tables gets updated. And sy-subrc is returned i.e., sy-subrc is returned for once and all.
A is for Asynchronous update. When you change data of one table, the sy-subrc is returned. And then updating of other affected tables takes place. So if system fails to update other tables, still sy-subrc returned is 0 (i.e., when first table gets updated).
Parameter 5 when you update database table, operation is either successful or unsuccessful or operation is successful with some warning. These messages are stored in internal table, which you specify along with MESSAGE statement. This internal table should be declared like BDCMSGCOLL, a structure available in ABAP/4. It contains the following fields:
1. Tcode: Transaction code
2. Dyname: Batch point module name
3. Dynumb: Batch input Dyn number
4. Msgtyp: Batch input message type (A/E/W/I/S)
5. Msgspra: Batch input Lang, id of message
6. Msgid: Message id
7. MsgvN: Message variables (N = 1 - 4)
For each entry, which is updated in database, table message is available in BDCMSGCOLL. As BDCMSGCOLL is structure, you need to declare a internal table which can contain multiple records (unlike structure).
Steps for CALL TRANSACTION method
1. Internal table for the data (structure similar to your local file)
2. BDCTAB like BDCDATA
3. UPLOAD or WS_UPLOAD function to upload the data from local file to itab. (Considering file is local file)
4. Loop at itab.
Populate BDCTAB table.
Call transaction <tcode> using <BDCTAB>
Mode <A/N/E>
Update <S/A>.
Refresh BDCTAB.
Endloop.
(To populate BDCTAB, You need to transfer each and every field)
The major differences between Session method and Call transaction are as follows:
SESSION METHOD CALL TRANSACTION
1. Data is not updated in database table unless Session is processed. Immediate updation in database table.
2. No sy-subrc is returned. Sy-subrc is returned.
3. Error log is created for error records. Errors need to be handled explicitly
4. Updation in database table is always synchronous Updation in database table can be synchronous Or Asynchronous.
Error Handling in CALL TRANSACTION
When Session Method updates the records in database table, error records are stored in the log file. In Call transaction there is no such log file available and error record is lost unless handled. Usually you need to give report of all the error records i.e., records which are not inserted or updated in the database table. This can be done by the following method:
Steps for the error handling in CALL TRANSACTION
1. Internal table for the data (structure similar to your local file)
2. BDCTAB like BDCDATA
3. Internal table BDCMSG like BDCMSGCOLL
4. Internal table similar to Ist internal table
(Third and fourth steps are for error handling)
5. UPLOAD or WS_UPLOAD function to upload the data from the local file to itab. (Considering file is local file)
6. Loop at itab.
Populate BDCTAB table.
Call transaction <tr.code> using <Bdctab>
Mode <A/N/E>
Update <S/A>
Messages <BDCMSG>.
Perform check.
Refresh BDCTAB.
Endloop.
7 Form check.
IF sy-subrc <> 0. (Call transaction returns the sy-subrc if updating is not successful).
Call function Format_message.
(This function is called to store the message given by system and to display it along with record)
Append itab2.
Display the record and message.
Check this program for session method using multiple transactions.
Have one BDC_OPEN_GROUP, multiple BDC_INSERT s and one BDC_CLOSE_GROUP.
You should have multiple BDC_INSERT s for multiple transactions.
call function BDC_OPENGROUP.
Build BDC data and cal lBDC_INSERT for transaction 1
Build BDC data and cal lBDC_INSERT for transaction 2
Build BDC data and cal lBDC_INSERT for transaction 3
call function BDC_CLOSE_GROUP.
