Diff between update queue and delta queue

hi all
can anyone tell me wats is the diff between update queue and delta queue? wats is delta queue and update queue?
wats are the possible system generated errors and custom generated errors?
Thanks,
Shreya

Hi Shreya,
Update queue(LBWQ) comes into the picture when you choose Queued Delta for the Datasource. the data first comes to the Update queue and than goes to the Delta queue, however if you have choosen Direct Delta than the posted record will directly go to the Delta queue(RSA7).
Here is the URLS for Roberto's weblog to understand the whole LO-Extraction process.

Difference Between Update Queue and Delta Queue

Hi Experts ,
Could u brief out the difference between Extraction Queue , Update Queue and Delta Queue ?

Hi
a) Serialized V3 Update(If you set this as your delta mode then data will populated into extraction queue tables)
This is the conventional update method in which the document data is collected in the sequence of attachment and transferred to BW by batch job.The sequence of the transfer does not always match the sequence in which the data was created.
b) Queued Delta(If you set this as your delta mode then data will be populated into update queue tables)
In this mode, extraction data is collected from document postings in an extraction queue from which the data is transferred into the BW delta queue using a periodic collective run. The transfer sequence is the same as the sequence in which the data was created
Delta queue is a table which collects data from extraction queue/update queue tables based on the frequency you have set(daily/hourly etc)..from these tables we will get delta records to bw with infopackage delta run..
Hope it helps
Thanks

How to delete the data in update queue and delta queue for Queued delta?

Dear BWers,
How do i delete the delta queue and update queue data before i fill the setup tables for a extraction based on Queued delta. Please help.
Thanks
Raj

Hi Raj,
I think you need some ground work for the LO extraction same as others here. Please read the 3 blogs expliciltly created for LIS by Robert Negro.

Difference between Direct delta and delta Queue

Hi,
1.ease explain me the concept of Direct delta and delta queue in LO extraction
2.Why set up tables are used and initially why the data is deleted for th setup tables.
3.Please explain me the LO extraction with an example.
Thanks
Alok

Dear Aloka,
1.
Direct delta:
transactional data or application posting will be directly available in the delta queue table with out any intermediate tables. then that data will be extracted from r/3 to bw.
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
Queued delta:
first the data posting will available in the extraction queue table. then there periodic job run take that data to queued delta table.
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
2.
Setup tables are used for Full/Initial Update.
Instead of pulling data from DB Tables directly, we r filling Setup tables and extracting data from the Setup tables, which dont have performance impact on DB Tables.
Setup tables are application specific.
It is cautious method to delete Setup tables before filling it for a specific DataSource.

What is differences extraction queue, delta queue and uddate queue ?

hi guru's
What is differences between extraction queue, delta queue and uddate queue ? can u describe briefly?
Thanks & Regards
nandi

Dear Prabha,
Basically when any document is posted in R/3, it is updated to the update table, from there it is taken to our delta queue for send it to BW side.
When extraction starts, data is sent to BW from delta queue. then again this cycle starts.
When you post any document in OLTP system (eg SAP R3),
say create sales order by VA01, then posting is made to application tables (VBAK/VBAP) through V1 and also to sm other tables through V2, Communication structure written to update queue/extraction queue/delta queue(directly) as per the update mode selected. V3 is always followed by V2 and we are supposed to schedule it.
From this delta queue, data is extracted by BW infopackages.
There are various update methods according to which extraction or delta queue are used, so when document posting takes place it also write data into extraction queue (through V1 update) and if we use queued delta method then this data is collected in collection run and written to delta queue and from this delta queue we request for data from BW.
There are lots of posts on SDN for this, please have a look on those.
one for your reference...

Clearing Extraction and Delta Queues

Hi Guys,
I have a quite a problem. I am needed to clear Extraction and Delta Queues, but because there are users in the system they just keep repopulating once i have cleared them. Now these queues have to be cleared for a SAP Upgrade and the Upgrade wont continue until both are clear.
I was wondering is there a way to clear both queues with users in the system making changes?
A quick response would be greatly appreciated!
Thanks in Advance,
Nick

Hi,
There is on program"RMBWV*"
where * is equal to application.
It is used to move the entries from extraction queue to delta queue.
After everthing is there in the rsa7,then you need
to run the info package untill the entries become "zero" in rsa7.
May be try to run more than once.
Note:-You need to take business down time ie lock all the user
so that during that time no one update any data.
Hope this i shelpful.
Thanks,
Saveen Kumar

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
Thanks,
JituK

Different between initial replication and delta replication

Hi,
What is different between initial replication and delta replication of the catalog to B2B?
Denis Khveshchenik

Initial replication will replicate the full catalog
Delta replication - The replication will be based on teh change pointer that have been updated, so only the items that have been changed since the last initial replication will be replicated. This should result in a quicker replication time.

Diff between update & modify

hi can anyone explain me that what is the diff between update & modify.
whether i can modify the database table with modify statement .
if yes then how?

Hi,
<b>MODIFY:</b>
To insert lines into a database table regardless of whether there is already a line in the table with the same primary key, use the following:
MODIFY <target> <lines>.
If the database table contains no line with the same primary key as the line to be inserted, MODIFY works like INSERT, that is, the line is added.
If the database already contains a line with the same primary key as the line to be inserted, MODIFY works like UPDATE, that is, the line is changed.
For performance reasons, you should use MODIFY only if you cannot distinguish between these two options in your ABAP program.
<b>UPDATE:</b>
The Open SQL statement for changing data in a database table is:
UPDATE <target> <lines>.
It allows you to change one or more lines in the database table <target>. You can only change lines in an ABAP Dictionary view if it only contains fields from one table, and its maintenance status is defined as Read and change. You may specify the database table <target> either statically or dynamically.

There are so many differences between the version in different objects
I will explain in two or more objects the difference
1 in the customer master in 4.6 version there is no partner function tab in the customer in xd01 t-code
and also there is no CIN tab in that version
but it is there in the 4.7 EE version
This is the major change from the 4.6cc to 4.7EE
2. in 4.7EE there is some settings that are related for CIN
which cannot be done in 4.7EE that means they need some patches for doing the configuration setting for the CIN
But we can do the same in the 6.0 version
These are the some of the settings that are differed in the two versions and in that two objects

In LSMW, what is diff between LSMW-BAPI and LSMW-IDOC

hello all
In LSMW, what is diff between LSMW-BAPI and LSMW-IDOC

Hi Swamy,
The differences between IDoc and BAPI are as follows:
IDOC
IDocs are text encoded documents with a rigid structure that are used to exchange data between R/3 and a foreign system.
Idocs are processed asynchronously and no information whatsoever is returned to the client.
The target system need not be always online. The IDOC would be created and would send the IDOC once the target system is available (tRFC concept). Hence supports guaranteed delivery.
With asynchronous links the sub-process on the client can be finished even if the communication line or the server is not available. In this case the message is stored in the database and the communication can be done later.
The disadvantage of asynchronous links is that the sub-process on the server cannot return information to the calling sub-process on the client. A special way for sending information back to the client is required. In addition, a special error handling mechanism is required to handle errors on the receiving side.
IDOCs may be more changeable from release to release.
IDOCs are poorly documented.
BAPI
BAPIs are a subset of the RFC-enabled function modules, especially designed as Application Programming Interface (API) to the SAP business object, or in other words: are function modules officially released by SAP to be called from external programs.
BAPIs are called synchronously and (usually) return information.
For BAPIs the client code needs to do the appropriate error handling.
Problems with synchronous links occur if the communication line or the server is temporarily not available. If this happens, the sub-process on the client cannot be finished (otherwise there would be data inconsistencies).
Synchronous links have the advantage that the sub-process on the server can return values to the sub-process on the client that has started the link.
BAPIs are not totally immune to upgrades.
BAPIs are reasonably well documented.
Reward points if useful.
Best Regards,
Sekhar

Diff between Thin client and Rich client

Hi Everyone,
Can someone give me a clear picture of the what is the diff between Thin client and Rich client.
Thanks,
Krishna

Hi,
thick client (rich client) has/stores all the data inside itself
so it can do application processing without the server with data
thin client uses resources from host computer (from server)
and wihtout that you are not able to work with that kind of client
does that answer your question ?

Diff between Seeburger Adapter and File Adapter

Hi All,
My company needs to interact with some banks and the banks are particular that they want SFTP, which is not supported by File Adapter, so we have decided to go with Seeburger adapter.
Now what are the differences between File adapter and seeburger adapter?
I believe that Seeburger adapter does not support File Content Conversion, Archiving etc.
Could you all pls put some light on the diff between file adapter and seeburger adapter when it comes to dealing with files?
Xier

Hi
You are aware with working of File Adapter.
The most direct way of using the Seeburger adaptors is to configure the BIC as a module. There is a software component from seeburger called bicmapper which will allow you to
1. Define or import the inbound message metadefinition in various formats ( edifact, xml,...)
2. Using a mapping create an xml variant as the output metadefinition or edifact in the other direction.
3. Create a one to one mapping between input en output.
4. Export the metadata in xsd or sda format for import in XI
5. Generate an SDA which can be deployed in XI and used as a module.
Have a look here,
