In LO Cockpit, Job contol job is cancelled in SM37

Question

Dear All
   I am facing one problem. Pl help me to resolve that issue.
When ever I am scheduling the delta job for 03 (Application Component), that is cancelled in SM37. Hence, I couldn't retrive those data from queued delta MCEX03 (smq1 or lbwq) to RSA7 because of job is cancelled. When I have seen that job log I got below Runtime Errors. Please hep me to resolve this issue
Runtime Errors         MESSAGE_TYPE_X
Date and Time          04.10.2007 23:46:22
Short text
The current application triggered a termination with a short dump.
What happened?
The current application program detected a situation which really
should not occur. Therefore, a termination with a short dump was
triggered on purpose by the key word MESSAGE (type X).
What can you do?
Note down which actions and inputs caused the error.
To process the problem further, contact you SAP system
administrator.
Using Transaction ST22 for ABAP Dump Analysis, you can look
at and manage termination messages, and you can also
keep them for a long time.
Error analysis
Short text of error message:
Structures have changed (sy-subrc=2)
Long text of error message:
Technical information about the message:
Message class....... "MCEX"
Number.............. 194
Variable 1.......... 2
Variable 2.......... " "
Variable 3.......... " "
Variable 4.......... " "
How to correct the error
Probably the only way to eliminate the error is to correct the program.
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"MESSAGE_TYPE_X" " "
"SAPLMCEX" or "LMCEXU02"
"MCEX_UPDATE_03"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
To save the description, choose "System->List->Save->Local File
(Unconverted)".
2. Corresponding system log
Display the system log by calling transaction SM21.
Restrict the time interval to 10 minutes before and five minutes
after the short dump. Then choose "System->List->Save->Local File
(Unconverted)".
3. If the problem occurs in a problem of your own or a modified SAP
program: The source code of the program
In the editor, choose "Utilities->More
Utilities->Upload/Download->Download".
4. Details about the conditions under which the error occurred or which
actions and input led to the error.
Thanks in advance

LO EXTRACTION:
First Activate the Data Source from the Business Content using “LBWE”
For Customizing the Extract Structure – “LBWE”
Maintaining the Extract Structure
Generating the Data Source
Once the Data Source is generated do necessary setting for
Selection
Hide
Inversion
Field Only Know in Exit
And the save the Data Source
Activate the Data Source
Using “RSA6” transport the Data Source
Replicate the Data Source in SAP BW and Assign it to Info source and Activate
Running the Statistical setup to fill
the data into Set Up Tables
Go to “SBIW” and follow the path
We can cross check using “RSA3”
Go Back to SAP BW and Create the Info package and run the Initial Load
Once the “Initial delta” is successful before running “delta” load we need to set up “V3 Job” in SAP R/3 using “LBWE”.
Once the Delta is activated in SAP R/3 we can start running “Delta” loads in SAP BW.
Direct Delta:- In case of Direct delta LUW’s are directly posted to Delta Queue (RSA7) and we extract the LUW’s from Delta Queue to SAP BW by running Delta Loads. If we use Direct Delta it degrades the OLTP system performance because when LUW’s are directly posted to Delta Queue (RSA7) the application is kept waiting until all the enhancement code is executed.
Queued Delta: - In case of Queued Delta LUW’s are posted to Extractor queue (LBWQ), by scheduling the V3 job we move the documents from Extractor queue (LBWQ) to Delta Queue (RSA7) and we extract the LUW’s from Delta Queue to SAP BW by running Delta Loads. Queued Delta is recommended by SAP it maintain the Extractor Log which us to handle the LUW’s, which are missed.
V3 -> Asynchronous Background Update Method – Here by seeing name itself we can understand this. I.e. it is Asynchronous Update Method with background job.
Update Methods,
a.1: (Serialized) V3 Update
b. Direct Delta
c. Queued Delta
d. Un-serialized V3 Update
Note: Before PI Release 2002.1 the only update method available was V3 Update. As of PI 2002.1 three new update methods are available because the V3 update could lead to inconsistencies under certain circumstances. As of PI 2003.1 the old V3 update will not be supported anymore.
a. Update methods: (serialized) V3
• Transaction data is collected in the R/3 update tables
• Data in the update tables is transferred through a periodic update process to BW Delta queue
• Delta loads from BW retrieve the data from this BW Delta queue
Transaction postings lead to:
1. Records in transaction tables and in update tables
2. A periodically scheduled job transfers these postings into the BW delta queue
3. This BW Delta queue is read when a delta load is executed.
Issues:
• Even though it says serialized , Correct sequence of extraction data cannot be guaranteed
• V2 Update errors can lead to V3 updates never to be processed
Update methods: direct delta
• Each document posting is directly transferred into the BW delta queue
• Each document posting with delta extraction leads to exactly one LUW in the respective BW delta queues
Transaction postings lead to:
1. Records in transaction tables and in update tables
2. A periodically scheduled job transfers these postings into the BW delta queue
3. This BW Delta queue is read when a delta load is executed.
Pros:
• Extraction is independent of V2 update
• Less monitoring overhead of update data or extraction queue
Cons:
• Not suitable for environments with high number of document changes
• Setup and delta initialization have to be executed successfully before document postings are resumed
• V1 is more heavily burdened
Update methods: queued delta
• Extraction data is collected for the affected application in an extraction queue
• Collective run as usual for transferring data into the BW delta queue
Transaction postings lead to:
1. Records in transaction tables and in extraction queue
2. A periodically scheduled job transfers these postings into the BW delta queue
3. This BW Delta queue is read when a delta load is executed.
Pros:
• Extraction is independent of V2 update
• Suitable for environments with high number of document changes
• Writing to extraction queue is within V1-update: this ensures correct serialization
• Downtime is reduced to running the setup
Cons:
• V1 is more heavily burdened compared to V3
• Administrative overhead of extraction queue
Update methods: Un-serialized V3
• Extraction data for written as before into the update tables with a V3 update module
• V3 collective run transfers the data to BW Delta queue
• In contrast to serialized V3, the data in the updating collective run is without regard to sequence from the update tables
Transaction postings lead to:
1. Records in transaction tables and in update tables
2. A periodically scheduled job transfers these postings into the BW delta queue
3.This BW Delta queue is read when a delta load is executed.
Issues:
• Only suitable for data target design for which correct sequence of changes is not important e.g. Material Movements
• V2 update has to be successful
Direct Delta: With this update mode, the extraction data is transferred with each document posting directly into the BW delta queue. In doing so, each document posting with delta extraction is posted for exactly one LUW in the respective BW delta queues.
Queued Delta: With this update mode, the extraction data is collected for the affected application instead of being collected in an extraction queue, and can be transferred as usual with the V3 update by means of an updating collective run into the BW delta queue. In doing so, up to 10000 delta extractions of documents for an LUW are compressed for each Data Source into the BW delta queue, depending on the application.
Non-serialized V3 Update: With this update mode, the extraction data for the application considered is written as before into the update tables with the help of a V3 update module. They are kept there as long as the data is selected through an updating collective run and are processed. However, in contrast to the current default settings (serialized V3 update), the data in the updating collective run are thereby read without regard to sequence from the update tables and are transferred to the BW delta queue.
V1 - Synchronous update
V2 - Asynchronous update
V3 - Batch asynchronous update
These are different work processes on the application server that takes the update LUW (which may have various DB manipulation SQLs) from the running program and execute it. These are separated to optimize transaction processing capabilities.
Taking an example -
If you create/change a purchase order (me21n/me22n), when you press 'SAVE' and see a success message (PO.... changed...), the update to underlying tables EKKO/EKPO has happened (before you saw the message). This update was executed in the V1 work process.
There are some statistics collecting tables in the system which can capture data for reporting. For example, LIS table S012 stores purchasing data (it is the same data as EKKO/EKPO stored redundantly, but in a different structure to optimize reporting). Now, these tables are updated with the txn you just posted, in a V2 process. Depending on system load, this may happen a few seconds later (after you saw the success message). You can see V1/V2/V3 queues in SM12 or SM13.
V3 is specifically for BW extraction. The update LUW for these is sent to V3 but is not executed immediately. You have to schedule a job (e.g. in LBWE definitions) to process these. This is again to optimize performance.
V2 and V3 are separated from V1 as these are not as real time critical (updating statistical data). If all these updates were put together in one LUW, system performance (concurrency, locking etc) would be impacted.
Serialized V3 update is called after V2 has happened (this is how the code running these updates is written) so if you have both V2 and V3 updates from a txn, if V2 fails or is waiting, V3 will not happen yet.
hope it will helps you.....
