Which Delta update mode we need to select for LO extractor

Hi All,
I would like to know which delta update mode we need to use for LO extractor.
Thanks,
Ram

Hi,
when there is more number of Delta recods we use "Queued Delta" . if number od records are less then Direct Delta.
when posting sequence is not mandatory "Unserialized V3 Update ".
but generally "Queued Delta" is used performance wise. (since delta records are posted with V3 job)
Best Regards.

Activation of Delta Update Mode:

Dear
Experts:
I have loaded the data with full update mode in ods, now i want to data with delta,
I have init with out datatransfer for enbaling delta, it is throwing an error msg mention below
Full updates already available in ODS ZODS_O06 ; Cannot update init./delta RSM 98
Need suggestion to move further:
Regards
Radha.

You have to convert the full update request to Repair full requests.
You can use RSSM_SET_REPAIR_FULL_FLAG program or RSSM_SET_REPAIR_FULL_REQUESTS function module.
In the program give Infocube as DSO name, datasource and source system from where you are loading data.
After this you would be able to load init request properly.

"Direct Delta" Update Method - Why need for Collective update

Hi folks,
I have been going through LO Cockpit in detail and read quite extensively about new update methods and still have one doubt.
1)Why there is "Job control" for "Direct Delta" Update method in LO Cockpit?.
If I understand Direct Delta correctly, Application data is directly posted to Delta Queue by SAP Update management using V1 and when the Delta request comes from BW it is read from the Delta queue. So...
2)why bother about collective run and
3)where exactly are we going to collect from - there is no intermediate storage like extraction Q or update tables?
One more question. I noticed that Delta queue is a stopped qRFC. what does this mean?

I-pod cannot update because all the playlists selected for no longer exsist

What does this mean?? I have tons of songs on my itunes, but now I have 0 on my ipod and can't figure out how to transfer them. THis is a new problem, they used to transfer just fine...HELP

You get this problem when the option 'Sync Music - Selected playlists' is being used to sync your iPod and then the playlist it has been updating from is deleted. Most people use this setting when the iPod is smaller than the iTunes library. If your library is larger than the capacity of your iPod, iTunes by default makes a new playlist called something along the lines of "Owner's iPod". If you for any reason delete it, you will not be able to sync your iPod.
Open iTunes and create a playlist to update your iPod from, call it -iPod to make it the first playlist in Sources. You can make it a smart playlist that picks the songs for you or just a normal one and drag whatever content you want to have into the playlist. If you are making a smart playlist limit it to just less than the size of your iPod (for example 3700MB for a 4G iPod Nano. Now connect your iPod and when it appears in the Source list click on the iPod icon to bring up the preference tabs in the main pane. Go to the Music tab and choose Sync Music and the Selected playlists radio button. Choose the playlist you just made from the selection and click Apply. You can also sync from any existing playlists by choosing the same setting, you just need to make sure that the size of the playlists don't exceed the capacity of your iPod:
iTunes: Creating playlists of your favorite songs
How to create a Smart Playlist with iTunes
Syncing Music to iPod
To make a random playlist go to File>New Smart Playlist.
Uncheck "Match the following rule"
Check "Limit to" put "3700" in the number box, choose "MB" from the first list box, choose "Random" from the next list box. Check "Live Updating"
When you want to change the selection in the smart playlist just delete everything in it and it will add a new selection. When you want to change the normal playlist just delete out what you don't want and drag in a new selection.

Diff between update modes

hi guru's
i have one doubt regarding lo extraction.
we have 3 types of update modes in lo extraction. those are
queued delta
direct delta
unserialized v3 update
when will u go for each delta mode
what are the advantages and disadvantages of each delta mode
plz reply me asap.
thank u
from
v.vijay

Hi,
Update Methods > Direct Delta, Queued, Non-serialized V3 Update and Serialized V3 (obsolete)
Direct Delta
Queued Delta
Un-serialized V3 Update
Serialized V3 Update (obsolete)
Direct Delta (update mode A): 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.
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
With this update mode, extraction data is transferred directly to the BW delta queues every time a document is posted. In this way, each document posted with delta extraction is converted to exactly one LUW in the related BW delta queues. If you are using this method, there is no need to schedule a job at regular intervals to transfer the data to the BW delta queues. On the other hand, the number of LUWs per DataSource increases significantly in the BW delta queues because the deltas of many documents are not summarized into one LUW in the BW delta queues as was previously the case for the V3 update.
If you are using this update mode, note that you cannot post any documents during delta initialization in an application from the start of the recompilation run in the OLTP until all delta init requests have been successfully updated successfully in BW. Otherwise, data from documents posted in the meantime is irretrievably lost. The restrictions and problems described in relation to the "Serialized V3 update" do not apply to this update method.
This update method is recommended for the following general criteria:
a) A maximum of 10,000 document changes (creating, changing or deleting documents) are accrued between two delta extractions for the application in question. A (considerably) larger number of LUWs in the BW delta queue can result in terminations during extraction.
b) With a future delta initialization, you can ensure that no documents are posted from the start of the recompilation run in R/3 until all delta-init requests have been successfully posted. This applies particularly if, for example, you want to include more organizational units such as another plant or sales organization in the extraction. Stopping the posting of documents always applies to the entire client.
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 DataSource into the BW delta queue, depending on the application.
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
With this update mode, the extraction data for the affected application is compiled in an extraction queue (instead of in the update data) and can be transferred to the BW delta queues by an update collective run, as previously executed during the V3 update.
Up to 10,000 delta extractions of documents to an LUW in the BW delta queues are cumulated in this way per DataSource, depending on the application.
If you use this method, it is also necessary to schedule a job to regularly transfer the data to the BW delta queues ("update collective run"). However, you should note that reports delivered using the logistics extract structures Customizing cockpit are used during this scheduling. This scheduling is carried out with the same report which is used when you use the V3 updating (RMBWV311, RMBWV312 or RMBWV313).There is no point in scheduling with the RSM13005 report for this update method since this report only processes V3 update entries. The simplest way to perform scheduling is via the "Job control" function in the logistics extract structures Customizing Cockpit. We recommend that you schedule the job hourly during normal operation - that is, after successful delta initialization.
In the case of a delta initialization, the document postings of the affected application can be included again after successful execution of the recompilation run in the OLTP (e.g OLI7BW, OLI8BW or OLI9BW), provided that you make sure that the update collective run is not started before all delta Init requests have been successfully updated in the BW.
In the posting-free phase during the recompilation run in OLTP, you should execute the update collective run once (as before) to make sure that there are no old delta extraction data remaining in the extraction queues when you resume posting of documents.
Using transaction SMQ1 and the queue names MCEX11, MCEX12 or MCEX13 you can get an overview of the data in the extraction queues.
If you want to use the functions of the logistics extract structures Customizing cockpit to make changes to the extract structures of an application (for which you selected this update method), you should make absolutely sure that there is no data in the extraction queue before executing these changes in the affected systems. This applies in particular to the transfer of changes to a production system. You can perform a check when the V3 update is already in use in the respective target system using the RMCSBWCC check report.
In the following cases, the extraction queues should never contain any data:
- Importing an R/3 Support Package
- Performing an R/3 upgrade
For an overview of the data of all extraction queues of the logistics extract structures Customizing Cockpit, use transaction LBWQ. You may also obtain this overview via the "Log queue overview" function in the logistics extract structures Customizing cockpit. Only the extraction queues that currently contain extraction data are displayed in this case.
The restrictions and problems described in relation to the "Serialized V3 update" do not apply to this update method.
This update method is recommended for the following general criteria:
a) More than 10,000 document changes (creating, changing or deleting a document) are performed each day for the application in question.
b) In future delta initializations, you must reduce the posting-free phase to executing the recompilation run in R/3. The document postings should be included again when the delta Init requests are posted in BW. Of course, the conditions described above for the update collective run must be taken into account.
Un-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.
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
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.
With this update mode, the extraction data of the application in question continues to be written to the update tables using a V3 update module and is retained there until the data is read and processed by a collective update run.
However, unlike the current default values (serialized V3 update); the data is read in the update collective run (without taking the sequence from the update tables into account) and then transferred to the BW delta queues.
The restrictions and problems described in relation to the "Serialized V3 update" do not apply to this update method since serialized data transfer is never the aim of this update method. However, you should note the following limitation of this update method:
The extraction data of a document posting, where update terminations occurred in the V2 update, can only be processed by the V3 update when the V2 update has been successfully posted.
This update method is recommended for the following general criteria:
a) Due to the design of the data targets in BW and for the particular application in question, it is irrelevant whether or not the extraction data is transferred to BW in exactly the same sequence in which the data was generated in R/3.
Serialized V3 (obsolete)
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

Flat file data load to BW datatarget-update mode

I am loading Revenue data using flat file. I am not going to overwrite anything in my futur updates.
each time if I load I have to add the values.
Can I create
Flat file -> ODS--> Cube or
Flat file -
> cube.
In the transfer structure which update mode I need to set .(FULL/Latest status of changed records / Additive delta)
I have to create 2 infopackages-Initial load /Delta load
I am in BW3.5 system
Please provide some lights
Thanks

Hi
If I understand ur question correctly, I think
u can create both
Flat file -> ODS--> Cube or
Flat file -
> cube.
as u like
I think for flat file loading there will be no Initial/ delta load, u can do only full update

Deadlock detected during SELECT FOR UPDATE - an application error?

I have a general question about how Oracle prevents deadlocks from affecting
applications: do I need to build support into the application for handling
deadlocks when they occur in this particular scenario, or should Oracle handle
this for me? I'd like to know whether this is "normal" behavior for an Oracle
application, or if there is an underlying problem. Consider the following situation:
Two sessions issue individual SELECT FOR UPDATE queries. Each query locates
records in the table using a different index. These indexes point to rows in a
different order from each other, meaning that a deadlock will occur if the two
statement execute simultaneously.
For illustrative purposes, consider these rows in a hypothetical table.
ALPHABET
alpha
bravo
charlie
delta
echo
foxtrot
golf
hotel
Index A results in traversing the table in ascending alphabetical order; index
B, descending. If two SELECT FOR UPDATE statements concurrently execute on this
table--one with an ascending order execution path and one in descending order--
the two processes will deadlock at the point where they meet. If Session A
locks alpha, bravo, charlie, and delta, while Session B locks hotel, golf,
foxtrot, and echo, then neither process can proceed. A needs to lock echo, and
B needs to lock delta, but one cannot continue until the other releases its
locks.
This execution path can be encouraged using hints. Executing queries similar to these on larger tables will generate the "collision" as described above.
-- Session A
select /*+ index_asc (customer) */
from customer
where gender = 'M'
for update;
-- Session B
select /*+ index_desc (customer) */
from customer
where gender = 'M'
for update;
Oracle will recognize that both sessions are in a stand-off, and it will roll
back the work performed by one of the two sessions to break the deadlock.
My question pivots on whether or not, in this situation, the deadlock gets
reported back to the application executing the queries as an ORA-00060. If
these are the ONLY queries executed during these sessions, I would think that
Oracle would rollback the locking performed in one of the SELECT FOR UPDATE
statements. If I understand correctly,
(1) Oracle silently rolls back and replays work performed by UPDATE statements
when a deadlock situation occurs within the scope of the update statement,
and
(2) A SELECT FOR UPDATE statement causes Oracle, at the point in time the cursor
is opened, to lock all rows matching the WHERE clause.
If this is the case, then should I expect Oracle to produce an ORA-00060
deadlock detection error for two SELECT FOR UPDATE statements?
I would think that, for deadlock situations completely within Oracle's control,
this should be perceived to the application invoking the SELECT FOR UPDATE
statements as regular blocking. Since the query execution plans are the sole
reason for this deadlock situation, I think that Oracle would handle the
situation gracefully (like it does for UPDATE, as referenced in (1)).
Notice, from the trace file below, that the waits appear to be from row locking,
and not from an artificial deadlock (e.g. ITL contention).
Oracle8i Enterprise Edition Release 8.1.7.4.0 - 64bit Production
With the Partitioning option

----- PL/SQL Call Stack -----
object line object
handle number name
58a1f8f18 4 anonymous block
58a1f8f18 11 anonymous block
The following deadlock is not an ORACLE error. It is a
deadlock due to user error in the design of an application
or from issuing incorrect ad-hoc SQL. The following
information may aid in determining the deadlock:
Deadlock graph:

Thanks for your response. In my example, I used the indexes to force a pair of query execution plans to "collide" somewhere in the table in question by having one query traverse the table via index in an ascending order, and another in descending. This is an artificial scenario for reproducible illustrative purposes, but similar collisions could legitimately occur in real world scenarios (e.g. a full table scan and an index range scan with lookup by ROWID).
So, with that said, I think it would be unreasonable for Oracle to report the collision as a ORA-00060 every time it occurs because:
(1) The UPDATE statement handles this situation automatically, and
(2) An ORA-00060 results in a 100+KB trace file being written out, only rational for truly erroneous situations.
I agree that, when the application misbehaves and locks rows out of order in separate SQL statements, then Oracle should raise an ORA-00060, as the deadlock is outside of its control. But in this case, the problem occurs with just two individual SQL statements, each within its own transaction.

LIS Update Mode

Hello Experts,
I am working in BI 7.0.
I have a question about 'Direct Delta'. I have planned to use 'Direct Delta' update mode for 2LIS_11_VAITM, 2LIS_13_VDITM and 2LIS_12_VCITM. There would be delta extractions of documents up to 10000 for my customer. Am I right about using Direct Delta' ?
And, when using 'Direct Delta' , what happens about Setting Tables? I mean, could you explain technically and step by step how to load data from R/3 while using 'Direct Delta' ? Should I use set-up tables?
Thank you very much.
Points waiting for you.

HI Muju,
In case of queued delta LUW's r posted to extractor queue
by scheduling V3job we move the documents from Extactor
queue to Delta queue and we extract LUW's from Deltaqueue
to SAP BW by running Delta loadsQueued delta maintains
Extractor log to handle the LUW's which r missed.
In case of Direct delta LUW's r directly posted to Delta
Queue(RSA7)and we extact the LUW's from DeltaQueue to SAP
BW by running Delta loads.It degrades the OLTP performance
becoz when LUW's r directly posted to DeltaQueue the
application is kept waiting until all the enhancement code
is executed.
Queued Delta is better than Direct Delta for performance reasons.
Hope it Helps

Any problem in changing the update mode.

Hi Gurur's,
                We have set Unserialized V3 update mode in R/3 production for 2lis_03_bf.
                We are getting '0' records while running delta.
                Now can we change the update mode to queued delta and run and for that what are the precautionary steps to be done.And will be the effect if we done like that happen.
Cheers,
Satish.M.R.

You will get clear idea about how the data flow differs in this 2 update modes

Delta update types

Hi gurus,
could you please suggest where to use and why to use why not to use delta update modes direct delta,queued delta serialized v3 update and unserialized v3 update
Thanks in advance,
Ram

HI,
In LO we have four types of Update modes for deltas(upto 4.7, from ECC6. onward we have only 3).
Direct Delta: If we maintain this update mode, all the LUWs are directly updated to Delta Queue at postings. This degrades the OLTP system performance and while updating the postings, the delta queue is locked, so not possible to extract the data at business hours. This update mode is best suitable if the transaction data is too small.
V3 Serialized: If we maintain the mode, the LUWs are updated to Update Tables. Then we have to run the V3 job to move the LUWs form Update Tables to Delta Queue but in serialized format ie., document 5001 is not updated if the document 5000 is posting.
V3 UnSerialized:If we maintain this mode, the above draw back can be overcome. But in case of both Ser... and Unser.... no possible of error handling the LUWs ie., once u run the V3 job, all the records in the Update Table are deleted. So if any error occurs while moving the data from Update Table to Delta Queue, again no chance to get data from update tables.
Queued Delta: This is the mode while overcomes the above drawbacks ie., error handing of LUWs is possible. This mode is suitable if the transaction data is huge.
Hope this helps u a lot......
Assigning Points is the way of saying Thanks in SDN
