Effect of commit
Hi All,
I am writing some code in a BADI. In my code I am calling some SAP function modules and in one of the function module there is a statement 'Commit work' . Will this has any effect on the overall transaction for which the BADI is implemented.
Regards,
Jeetu
hi.
COMMIT WORK is used to make the following FM execute immediately. This will put no adverse effect on the BADI implementation.
Reward if useful.

Hi all,
10.2.0.1
RHEL4
I am inserting some data to a remote location through database link.
SQL>insert into tbl1@dblnk select * from tbl1;
How should i commit?
How would commit take effect?Commit as normal. Oracle will take care of it using two-phase commit.
For more information see:

Hi,
Can anyone tell me what happens when we explicitly write " COMMIT " or " COMMIT WORK" statement in module pool.
Thankshi Amit..
WELCOME TO SDN
COMMIT
Variants:
1. COMMIT WORK.
2. COMMIT CONNECTION con.
Effect
Executes a database commit and thus closes a Logical Unit of Work ( LUW) (see also Transaction Processing). This means that:
All database updates are made irrevocable and cannot be reversed with ROLLBACK WORK
All database locks are released.
COMMIT WORK belongs to the Open-SQL command set.
Variant 1
COMMIT WORK.
Addition:
... AND WAIT
Effect
COMMIT WORK also
Calls the subroutines specified by PERFORM ... ON COMMIT
Executes asynchronously any update requests (see CALL FUNCTION ... IN UPDATE TASK) specified in these subroutines or started just before
Processes the function modules specified in CALL FUNCTION ... IN BACKGROUND TASK
Resets the time slice counter to 0.
Ensures that the locks of the SAP locking concept are handled in accordance with its SCOPE Parameter.
Executes a database commit on all database connections
Closes all open database cursors (OPEN CURSOR) on all database connections
Releases all database locks on all database connections
After the COMMIT WORK has been executed, the event RAISE_TRANSACTION_FINISHED of the class CL_SYSTEM_TRANSACTION_STATE with parameter value CL_SYSTEM_TRANSACTION_STATE=>COMMIT_WORK is triggered. However, this does not apply to the COMMIT WORK at the end of the update.
The Return Code SY-SUBRC is set to 0.
Notes
All subroutines called with PERFORM ... ON COMMIT are processed in the LUW concluded by the COMMIT WORK command. All V1 update requests specified in CALL FUNCTION ... IN UPDATE TASK are also executed in one LUW. When all V1 update requests have been successfully concluded, the V2 update requests (update with start delayed ) are processed, each in one LUW. Parallel to this, the function modules specified in CALL FUNCTION ... IN BACKGROUND TASK are each executed in one LUW per destination.
COMMIT WORK commands processed within CALL DIALOG processing do all of the following:
- A database commit on all database connections (see above),
- Close all open database cursors on all database connections
- Reset the time slice counter
- Call the function modules registered in CALL DIALOG processing using CALL FUNCTION IN BACKGROUND TASK
However, subroutines and function modules called with PERFORM ... ON COMMIT or CALL FUNCTION ... IN UPDATE TASK in CALL DIALOG processing are not executed in the calling transaction until a COMMIT WORK occurs.
Since COMMIT WORK closes all open database cursors, any attempt to continue a SELECT loop after a COMMIT WORKresults in a runtime error. For the same reason, a FETCH after a COMMIT WORK on the now closed cursors also produces a runtime error. You must therefore ensure that any open cursors are no longer used after the COMMIT WORK.
COMMIT WORK may not be used during the update (CALL FUNCTION ... IN UPDATE TASK) or during the execution of FORMs that were registered using PERFORM ... ON COMMIT or PERFORM ... ON ROLLBACK.
With batch input and CALL TRANSACTION ... USING, COMMIT WORK successfully concludes the processing.
Addition
... AND WAIT
Effect
The addition ... AND WAIT makes the program wait for the type V1 update (update with immediate start) to be executed.
The Return Code is set as follows:
SY-SUBRC = 0:
The update was performed successfully.
SY-SUBRC <> 0:
The update was not performed successfully.
Variant 2
COMMIT CONNECTION con.
Effect
The COMMIT command is not executed on the standard database, but only on the secondary database connection specified with con. con is the name of the database connection as it was specified in the table DBCON in the column CON_NAME. The database connection con can also be specified dynamically in the form (source_text) - the source_text field contains the name of the database connection as ABAP Source Code.
On the specified secondary database connection, the database commit:
Closes all open database cursors (OPEN CURSOR)
Releases all database locks
Note
Because all open database cursors are closed with the COMMIT, the attempt to continue a SELECT loop after a COMMIT causes a runtime error. For the same reason, a FETCH after the COMMIT to the now closed cursor causes runtime error. You must ensure that open cursors are no longer used after the COMMIT. The only exception are cursors that were opened using the WITH HOLD addition. -
Accounting Entries of Outgoing Excise Invoice and Commercial Invoice
Hi All,
I am using SBO 2005 B. After adding Excise Invoice and Comm. Invoice. I am checking the A/c. effect from Comm. Invoice -> Accounting Tab. and click on the link. It is creating two entries. The Entry it opens is as below..
Account Debit Credit
C01735 -A D Enterprice 46500
221202 - CST Payable 911.76
412001 - Sales Treding Gujarat 40000.00
510010 - Excise Duty 5587.75
420011 - Rounding Off 0.49
when i go to its previous entry, it shows me below entry...
Account Debit Credit
221225 - Excise Duty Payable 5425.00
Cess On Excise - Payable 162.75
510010 - Excise Duty 5587.75
I have doubt i have enter wrong accounts in G/L account determination. - > generatl - > CENVAT
Can any body explain me wht accounts i have to enter there.
Thanks and regards..
Chintesh SoniHi Chintesh Soni,
The A/c 510050 is a CENVAT Clearing A/c that is set in the G/L Account Determaination - General Tab - Outgoing CENVAT Clearing Account.
This a/c is a clearing a/c that is debited when Outgoing Excise Invoice is created and credited when Invoice is created.
Plese refer to the G/L posting of A/c 510050. You may find
1) A debit entry for Rs. 5587.75 which is posted because of the Outgoing Excise Invoice
2) A credit entry for Rs. 5587.75 which is posted because of the Invoice
Hope this clarifies your doubts.

HOW do I create a SIMPLE fading slideshow in dreamweaver CS5?????
I would like to have a slow fading slideshow of a few images relating to the web page that the user is on.
I have a seperate div tag, with the space 235 x 440 pixels allowed for the images. All I want is the slideshow to fade in and out of one another using 3 or 4 photos, no text, no control panel or thumbnails or any other frills, just basic good quality photos fading in a looped slideshow.
I just want that when the page loads up that the slideshow starts automatically and slowly loops continuously until the user changes page.
I have seen animated gifs from photoshop, which are no good because the image quality is awful, and in fireworks, where it comes with either thumbnails or a control panel for the user to navigate manually the images. I don't want that. Can it be done easily in flash? or does dreamweaver have an answer?
Surely there must be a simple and basic way in dreamweaver alone to just swap/fade an image with another image a few times and thats that? no?
If it can't be done in dreamweaver, PLEASE tell me which program it can be done in and how.
Many many many thanks in advance for anyone with an easily explained solution.

SAP LUW
Since, as a rule, an application program is processed by several work processes in succession, and every change of the work process is linked with an implicit database commit , an application program is not automatically linked with a single database LUW. This applies in particular to dialog-oriented applications, in which one database LUW is assigned to one dialog step.
To ensure the data consistency of application programs that are executed across different work processes, the application statements are not directly executed in an SAP LUW, rather, are first registered and then executed by a single work process, that is, in a single database LUW.
Two techniques are available for bundling the change statements in a database LUW:
Bundling via function modules (update)
Through the statement CALL FUNCTION...IN UPDATE TASK, an update function module is registered for subsequent execution in an update work process.
Bundling via function modules (transactional RFC)
Through the statement CALL FUNCTION... IN BACKGROUND TASK DESTINATION, a remote- compatible function module is registered for subsequent asynchronous execution via the RFC interface (transactional RFC ).
Bundling via subprograms
Through the statement PERFORM ... ON COMMIT, a subprogram is registered for subsequent execution in a different work process.
Statements for SAP LUWs
A SAP LUW is controlled via the Open SQL statements COMMIT WORK, ROLLBACK WORK and SET UPDATE TASK LOCAL.
Note
A function module can be classified either as an update function module or remote-compatible, but not both at the same time. The update helps realize SAP LUWs within an SAP System, while the transactional RFC creates LUWs in distributed systems.
COMMIT WORK
Variants:
1. COMMIT WORK [AND WAIT].
2. COMMIT CONNECTION con.
Effect
Terminates an SAP LUW and stores the changes.
Variant 1
COMMIT WORK [AND WAIT].
Effect
The statement COMMIT WORK completes the current SAP LUW and opens a new one, storing all change requests for the currenta SAP LUW in the process. In this case, COMMIT WORK performs the following actions:
It executes all subroutines registered using PERFORM ON COMMIT.
It triggers an internal event in Object Services that ensures the registration of changes in persistent objects as the last update function module, as well as the subsequent initialization of persistent object attributes.
It initiates the processing of all registered update function modules in the update work process.
This executes all high-priority update function modules registered using CALL FUNCTION ... IN UPDATE TASK in the order of their registration and in a common database LUW. If you do not specify the addition AND WAIT, the program does not wait until the update work process has executed it (asynchronous updating). If you specify the addition AND WAIT, however, program processing after COMMIT WORK will not continue until the update work process has executed the high-priority update function modules (synchronous updating).
If all high-priority update function modules are completed successfully, the statement executes the low-priority update function modules together in a common database LUW.
In parallel, it also executes the individual function modules registered using CALL FUNCTION ... IN BACKGROUND TASK DESTINATION in a separate database LUW for each destination.
It handles all SAP locks set in the current program according to the value of the formal parameter _SCOPE of the corresponding lock function modules.
It triggers a database commit that also terminates the current database LUW.
The completion of statement COMMIT WORK triggers the event TRANSACTION_FINISHED of the system class CL_SYSTEM_TRANSACTION_STATE, where the parameter KIND has the value of the constant CL_SYSTEM_TRANSACTION_STATE=>COMMIT_WORK.
If the statement COMMIT WORK is executed by calling special programs, be aware of the following:
In a program executed using batch input, or if you have called the program using the USING addition of the statement CALL TRANSACTION, COMMIT WORK terminates the batch input processing when using the corresponding settings.
In a program called using CALL DIALOG, COMMIT WORK initiates the processing of subroutines or updated function modules registered using PERFORM ... ON COMMIT and CALL FUNCTION ... IN UPDATE TASK. Therefore, it does not complete the current SAP LUW. The SAP LUW cannot be completed until you execute the COMMIT WORK statement in the calling program.
You cannot execute the COMMIT WORK statement during the updating procedure or during the execution of subroutines registered using PERFORM ... ON {COMMIT|ROLLBACK}.
System fields
sy-subrc Meaning
0 You have specified the AND WAIT addition, and the updating of the update function modules was successful.
4 You have specified the AND WAIT addition, and the updating of the update function modules was not successful.
The COMMIT WORK statement always sets sy-subrc to 0 if the AND WAIT addition is not specified.
Note
The COMMIT WORK statement closes all database cursors . Open SQL statements that access a database cursor later ( SELECT loop and FETCH) raise an exception that cannot be handled.
Variant 2
COMMIT CONNECTION con.
Note
This statement is for internal use only.
It cannot be used in application programs.
Effect
The COMMIT command is not executed on the standard database, but only on the secondary database connection specified by con. con is the name of the database connection as it was specified in the table DBCON in the column CON_NAME. The database connection con can also be specified dynamically in the form (source_text) - the source_text field contains the name of the database connection. The source_text field must be of the type C or STRING.
On the specified secondary database connection, the database commit:
Closes all open database cursors (OPEN CURSOR)
Releases all database locks
Note
Note that the COMMIT CONNECTION DEFAULT statement unlike COMMIT WORK executes a pure database commit on the DEFAULT connection.
Exceptions
Non-Catchable Exceptions
Cause: COMMIT WORK is not possible in a FORM that was called using PERFORM ... ON COMMIT.
Runtime Error: COMMIT_IN_PERFORM_ON_COMMIT
Cause: COMMIT WORK is not allowed in the update.
Runtime Error: COMMIT_IN_POSTING
ROLLBACK WORK
Variants:
1. ROLLBACK WORK.
2. ROLLBACK CONNECTION con.
Effect
Terminates a SAP-LUW without storing the changes.
Variant 1
ROLLBACK WORK.
Effect
The statement ROLLBACK WORK closes the current SAP-LUW and opens a new one. In doing so, all change requests of the current SAP-LUW are canceled. To do this, ROLLBACK WORK carries out the following actions:
Executes all subprograms registered with PERFORM ON ROLLBACK.
Deletes all subprograms registered with PERFORM ON COMMIT.
Raises an internal exception in the Object Services that makes sure that the attributes of persistent objects are initialised.
Deletes all update function modules registered with CALL FUNCTION ...IN UPDATE TASK from the VBLOG and deletes all transactional remote Function Calls registered with CALL FUNCTION ... IN BACKGROUND TASK from ARFCSSTATE and from ARFCSDATA.
Removal of all SAP locks set in the current program in which the formal parameter _SCOPE of the lock function module was set to the value 2.
Triggers a database rollback, which also ends the current database-LUW.
After completion of the statement COMMIT WORK, the event TRANSACTION_FINISHED of the system class CL_SYSTEM_TRANSACTION_STATE is raised, in which the parameter KIND has the value of the constant CL_SYSTEM_TRANSACTION_STATE=>ROLLBACK_WORK.
Variant 2
ROLLBACK CONNECTION con.
Note
This statement is for internal use only.
It cannot be used in application programs.
Effect
The ROLLBACK-statement is not executed on the standard database but only on the secondary database connection, specified through con. con is the name of the database connection as it was specified in table DBCON in column CON_NAME. The database connection con can also be specified dynamically in the form (source_text), in which the field source_text contains the name of the database connection. The field source_text must be of the type C or STRING.
Notes
As all opened database cursors on the respective database connections are closed at ROLLBACK, the attempt to continue a SELECT-loop after a ROLLBACK, leads to a runtime error. Due to the same reason, a FETCH after a ROLLBACK to the then closed cursor, leads to a runtime error. You have to make sure that cursors that are still open, are no longer used after ROLLBACK.
After execution of the statement ROLLBACK, SY-SUBRC is always equal to 0. It is not necessary to check if SY-SUBRC is unequal to 0 after ROLLBACK.
ROLLBACK must not be used during update (CALL FUNCTION ... IN UPDATE TASK) or during the execution of FORMs, which were registered with PERFORM ... ON COMMIT resp. PERFORM ...ON ROLLBACK.
The statement ROLLBACK WORK is implicitly executed if a message of the type A is treated with the addition ERROR_MESSAGE when calling a function module with CALL FUNCTION.
Exceptions
Non-Catchable Exceptions
Cause: ROLLBACK WORK is not allowed within a FORM that is called with PERFORM ... ON COMMIT or PERFORM ... ON ROLLBACK.
Runtime Error: ROLLBACK_IN_PERFORM_ON_COMMIT
Cause: ROLLBACK WORK is not allowed within an update.
Runtime Error: ROLLBACK_IN_POSTING
SET UPDATE TASK LOCAL
Syntax
SET UPDATE TASK LOCAL.
Effect
This statement specifies that the high-priority update function modules - registered during the current SAP LUW using CALL FUNCTION ... IN UPDATE TASK - are registered in the ABAP memory instead of the VBLOG database table. In addition, it specifies that the current work process and not the update work process run these modules during the current database LUW, when the COMMIT WORK statement is executed. This statement has no effect on low-priority update function modules.
At the beginning of every SAP LUW, the local update function is deactivated. If you wish to use it, you must reactivate it again before the first update function module is registered.
System fields
sy-subrc Meaning
0 The local update function is activated.
1 The local update function has not been activated, because the program has already registered at least one update function module for the normal updating procedure in the current SAP-LUW.
Notes
The local update function performs a synchronous update according to the COMMIT WORK statement, independent of the addition AND WAIT.
The occurrence of a database rollback during the local update affects all previous change requests. -
I need help with the query
Here is what I need
For a particular comm record if there is no Salary record where comm:Date = Salary:Date, then
• Find maximum dated Salary record as of comm:Date.
• Clone this record and set Salary:Date = comm:Date
• Set Salary:rate = comm:rate
Like wise for a particular Salary record If there is no comm record where Salary:Date = comm:Date then
• Find maximum effective dated comm record as of Salary:Date
• Apply Rate 2 amount from this maximum effective dated record to Salary record i.e. Set Salary:rate = comm:rate
Example
Salary Table :
ID Sal_Date Rate Hours
1 07/01/2011 400.00 40
2 02/15/2011 200.00 40
3 01/01/2011 160.00 40
Sal_comm Table:
Sal_Date comm_Rate
1 07/01/2011 10.00
4 03/01/2011 7.50
3 01/01/2011 4.00
I need to merge comm_Rate column in Salary table, since there is no salary record as off 03/01/2011, I need to find the maximum dated salary record as of 03/01/2011
i.e. the record dated 02/15/2011. Now I need to clone that salary record, set the SAL_date as 03/01/2011 and update Rate2 amount. So the record set will be like:
Sal_Date:
id sal_Date Rate Hours comm_Rate
1 07/01/2011 400.00 40 10.00
4 03/01/2011 200.00 40 7.50
2 02/15/2011 200.00 40 4.00
3 01/01/2011 160.00 40 4.00So you need all used dates as the "driving" dataset. And you need the according data for each of these.
WITH salary_table as
(select 1 id,to_date('07/01/2011','MM/DD/YYYY')sal_date,400 rate,40 hours from dual union all
select 2 id,to_date('02/15/2011','MM/DD/YYYY')sal_date,200 rate,40 hours from dual union all

select 3 id,to_date('01/01/2011','MM/DD/YYYY')sal_date,4 comm_Rate from dual)
select to_char(all_dates.sal_date,'MM/DD/YYYY') sal_date,sal.rate,sal.hours,com.comm_rate
from (select sal_date from salary_table
union
select sal_date from sal_comm) all_dates
inner join (select s1.*,lead(sal_date-1,1,to_date('31/12/9999','DD/MM/YYYY')) over (order by sal_date) next_sal_date

What would happen if this runs?
This is a 'real' code example that i found in this program. Could this cause connection pools to not be relased
Connection con = null;
stmt = con.createStatement();
int ret = stmt.executeUpdate(simple query);
con.commit();
con.rollback();
con.commit();
con.closeConnection con = null;
stmt = con.createStatement();You will get a NullPointerException here. :P
If we assume that you are getting a Connection from a DataSource...
int ret = stmt.executeUpdate(simple query);
con.commit();This should commit the updates (even if the auto-commit mode is set to false). It releases all the previous savepoints as well.
con.rollback();This won't have any effect.
con.commit();Neither would this.
con.close();If all this code is in one block, there is no guarantee that the connection will be closed. This should be in a finally block preferably. :) -
Detailed transaction process documentation?
Hello,
I am working currently on a project based on "Oracle NoSQL" as the head storage unit. I am a bit curious, how ONDB handles their transactions. I have scoured the attached documentation but without success. The only thing I could find were headlines or marketing sentences (like "Flexible ACID transactions, a la Berkley DB")
Oracle NoSQL Database transactions
Oracle NoSQL Database (Version: 12cR1.2.1.57 Enterprise Edition, 2014-01-10 06:21:46 UTC
Oracle Berkeley DB Java Edition | Oracle Berkeley DB
http://indico.cern.ch/getFile.py/access?resId=0&materialId=slides&confId=159716
In the documentation of Berkley DB I have found a section claiming that BDB handles their transactions through JTA. Since ONDB is based on Berkley DB I've assumed that the transactions will be handled the same way. Please correct me if i am wrong.
However, this is not the result I would like to hear. Are there any detailed documentation for the transaction processing?
If anyone of you have an idea or a tip where I could find such a thing?
greeting
SaschaHi Sascha,
The short answer is that you can perform KVStore.execute operations:
execute(List<Operation> operations) (see execute)
Operations on records with the same major key, but different minor keys will be wrapped in an ACID transaction. All other single-record operations are in effect "auto-commit" transactions. You can perform CAS/RMW style operations using putIfVersion and deleteIfVersion.

DB Version:11g
From 11g'S Concepts guide
When a user commits a transaction, the transaction is assigned a system change number (SCN), which Oracle Database records along with the transaction's redo entries in the redo log.
Question1:
The documentation says that the transaction is assigned an SCN when there is a COMMIT. But isn't it more correct to say that the entire database is assigned a new SCN when there is a commit in a transaction?
Lets say:
At time 19:23:14:34 a transaction commits and Database is assigned 1198382929 as the SCN
one millisecond later
At time 19:23:14:35 a transaction commits and Database is assigned 1198382930 as the SCN
.Like above there can be 5 SCNs in one 'second' and 100 SCNs in the next second. But at any give time, for the database there is only one unique SCN and it is ever increasing. Am i right?NKU wrote:
Please read it little bit more carefully, it says when we commit any transaction, that transaction is assigned a SCN but it does not say that when transaction is committed, a SCN is generated. SCN is generated continuously in the database representing the database time (internal clock), only thing is when we commit a transaction, SCN at that particular time is assigned to that transaction.
Something has to be a trigger for the SCN to change - and the most common trigger if you are running single-instance Oracle is a commit. In effect, the commit DOES generate the SCN. (There are three other triggers for the SCN to change that I know of, but in most cases a commit - or rollback, of course - is the most common cause of a new value for the SCN being generated).

IRONPORT ALIAS .TXT FILE NOT IN BOTH CLUSTERS
I have a .txt for email redirection (alias - import/export) which appear only within one cluster, the other cluster is without alias .txt at all. Is it neccesary for the alias to be contained within both. Could someone provide answer or direct me to website which contains the info.
To apply an Exported Alias file to another ESA (or a cluster of ESAs), you must Import that data to the other ESA or Cluster. First you must upload the file to the ESA that will be Importing the data. The upload is done via SCP (preferred for security) or FTP and the file must exist in the directory called 'configuration'.
Once the file is uploaded, you can do the Import from the CLI using these steps:
x1070r01.csw> aliasconfig
No aliases in table.
Choose the operation you want to perform:
- NEW - Create a new entry.
- IMPORT - Import aliases from a file.
[]> import
Enter the name of the file on machine "x1070r01.csw" to import:
[]> exported_file.txt
Once all the data is Imported, it will take effect upon 'commit'.

So far, it is happening to 4 sites that I work with. Yes, they all use the same server, and the server company swears it is not their end. I don't quite understand what you mean "is it coming from a web page?" I edit and upload pages in Dreamweaver and then when I try to check the edited pages in Chrome, Firefox, Opera or Safari on 3 different computers that I have to work on, I get the error. If I edit in Dreamweaver and then use Core FTP LE to upload, then check the pages, I do not get the error. -
How to solve this: left-hand operand of comma has no effect?
hello, i am getting an error updating this package after libpng update... any clues?

thanksThose warnings should not be causing the compilation to error out. Look further back in the log for things marked 'error:'.

Relative newb to Flash and not sure what the issue is but I have a shelf opening and closing effect The timeline is 45 frames long and when the shelf is out it has this AS3 code in it:
import flash.events.MouseEvent;
stop();
ShelfOpen,addEventListener(MouseEvent.CLICK, closeShelf);
function closeShelf(evt:MouseEvent){
gotoAndPlay(17);
Once clicked, the shelf closes and only a sliver of the shelf appears. The person can re-open it by clicking the sliver at frame 30 using this code:
import flash.events.MouseEvent;
stop();
ShelfOpen,addEventListener(MouseEvent.CLICK, openShelf);
function openShelf(evt:MouseEvent){
gotoAndPlay(31);
In the last frame (45) I have the code:
gotoAndStop(16)
which should return the shelf to its open position and allow the user to close it again if they click in the shelf, but it seems to be listening at at frame 30 and just running the Open Shelf motion again. I would just like the user to be able to open and close the shelf as they like. Any help would be apprecaited.
-DCSee if removing the event lsteners in the event handlers helps, as in...
ShelfOpen.addEventListener(MouseEvent.CLICK, closeShelf);
function closeShelf(evt:MouseEvent){
ShelfOpen.removeEventListener(MouseEvent.CLICK, closeShelf);
gotoAndPlay(17);
(similarly for the other)
and make sure you are not using commas after ShelfOPen like you did in the code you posted.
