2LIS_02_ITM enhancement & delta initialization

Hi gurus,
i have enhanced 2LIS_02_ITM.
In EKKO & EKPO table there are data: when i run the initialization package, no data are extracted.
What is the problem?
Thanks in advance!

Hi,
To delete setup tables:
1. Go to tcode - LBWG
2. Select the application
3, click on execute button
Steps to fill.
1. Go to tcode - start with Ol*..depends on the application.
2. Enter all the required selections/parameters
3, Execute it in the background/
4. check the entries in rsa3 tcode.
Fill setup tables
Tocde OLI*BW Path is ->tcode SBIW->Business Information Warehouse->Settings for Application-Specific DataSources->Logistics->Managing Extract Structures->Initialization->Filling in the Setup Table->Application-Specific Setup of Statistical Data->Perform Setup - SD Sales Orders
Ex. OLI7BW for setup for SD sales orders.In this screen mention the values for document data restrictions such as Sales organization, company code etc, Enter name of run and provide date of termination & time -> future date and time. The setup job will contunue running till this date& time and then will terminate.
Excute the job in background
Points to be taken care of:
1. Stop/put on Hold all batch jobs for that application. This is because there will be changes in base tables of extractor due to batch jobs and these will not be captured.
2. Lock out all users to avoid changes in base tables as result of transactions update.
Above steps are recommended by SAP in order to avoid data loss. However if you are sure that data related to setoup tables(historical data) which is closed- No changes possible)then you don't need to observed above 2 steps.
Cheers!

Delta Initialization vs Delta Update

We're having some issues with performance when loading our GL cube. What I would like to do is perform many delta initializations, each delta inititialization containing one month/period.
My confusion is in the fact that the last time I attempted this, when I subsequently went to run my delta UPDATE the same selection criteria was automatically inserted into my delta update.
So for example my INIT may look like this;
REQUEST1: Selection = 001.2005
REQUEST2: Selection = 002.2005
etc........etc...
REQUEST12: Selection = 012.2005
Next the UPDATE info package seems to inherit the same criteria... doesn't this mean it will not update anything beyond that criteria??
I'm just wondering if it is possible to do an incremental initialization and still be able to enable delta updates for future periods?
Thanks!

Hi Patrick,
The delta update will load the data as per the selections made in the Init run. A delta requested after several initializations, contains the sum of all the successful initial selections as a selection condition. This selection condition can then no longer be changed for the delta.
Take a look here for more info:

Early Delta Initialization option in Production system

Hi Experts,
I have seen some threads related to Early Delta initialization in this forum. I have a question regarding this option.
To minimize the downtime/block users in the R/3 production system during set up tables fillup I would like to use the Early delta option. Please give your suggestions on the following procedure:
For Sales Orders, billing and Deliveries
1. Initialize Early delta in the BI system.
2. Go and fill setup tables
3. Do a full load to BI
4. Run delta job in R/3 (LBWE)
5. Run delta job in BI Info package
Do we miss any documents in this process for e.g. during set up tables fill up changes to existing documents or newly created sales orders.
I feel we won't miss. All changes will be reflected in Delta queue. And even newly created orders also will be coming to delta queue.
Please let me know if I am wrong.
Thank you.

Need Clarification on this thread,
According to my understanding, during the filling of set up table if a user does any posting, then the data available in BW will be incorrect.
am i right?
In your sequence the 4th step
4. Run delta job in R/3 (LBWE), this means you are using queued or unseriallized v3 update.
Early delta iniliazation essentially of no advantage because, as conventional initialization procedures, you can readmit document
postings after successfully filling the setup tables.
can anybody clear my doubt. is it possible during setup table filling user can post a document.
I know the documents will be collected in the queue. But the data loaded to bw will be incorrect right?
Regards,
Anand.

Extraction, Flat File, Generic Data Source, Delta Initialization

Extraction, Flat File, Generic Data Source, Delta Initialization
I have couple of questions regarding data extraction.
1.     If you have Data Source a Flat File e.g. Excel file I know that you have to create Data Source at BW side. How do you upload updates, by selecting Delta Update when executing next Data Load? Do you ever u201Cconvertu201D this Excel file into Application Tables to become SAP Source 
2.     Can you please give me example of situation where you had to create Generic Data Source? What is difference between Time Stamp, Calend. Day and Numeric Pointer. Which one is most common to select?
3.     I read somewhere that Generic Data Source does not have Setup Table. I thought that you have to have Setup Table in order to load transaction Data otherwise you will lock the Application Tables. Where am I going wrong im my thinking please?
4.     What are steps in terms of IP before, under and after Delta Initialization. I belive that you can do two ways:
Full Update - Initialize Delta Process (without Data Transfer) u2013 Delta Update or
Initialize Delta Process (with Data Transfer) u2013 Delta Update
Am I right? What is most common method and why?
5.     If you want to add a filed in Data Source after 6 month using it, you want to do it without re-init Delta Queue. You add field in RSA6, then provide info for ABAP to populate new filed (info u2013 name of Data Source, Extract Structure, field added, name of Application Table which contains the field). How does it work now as there is no SetUp table it has been deleted after Initialisation? How does Delta Queue know that it is going to receive data which has been expanded by one field or it may does not need to know at all?
THANKSSSSSSSSSs

Hi,
1. If you have Data Source a Flat File e.g. Excel file I know that you have to create Data Source at BW side. How do you upload updates, by selecting Delta Update when executing next Data Load? Do you ever u201Cconvertu201D this Excel file into Application Tables to become SAP Source
Once you create Datasource for A flat file extraction then it is file source system specific hence you cont change to Application table source Data source
In info package you can change the source as application server instead of desktop no need to change the DS
2. Can you please give me example of situation where you had to create Generic Data Source? What is difference between Time Stamp, Calend. Day and Numeric Pointer. Which one is most common to select?
When we don't find any standard extractor then we can go for Generic(if i want information sales along with finance information in a data source then generally we dont get standard one hence we can go for generic DS)
Check the below link for More about generic DS .
http://wiki.sdn.sap.com/wiki/display/BI/Generic+Extraction
for Delta capturing you can use
Timestamp(if the table has time stamp filed so it can stamp the last changed record in that table hence it is easy to get delta based on the time stamp)
Calday- (If the table doesn't have the Timestamp filed then search for Calday where you can stamp the delta based on the date when documents are changed )
Numericpointer : If the table doesn't above both then we go for this option where you can the numeric value change stamp )
3. I read somewhere that Generic Data Source does not have Setup Table. I thought that you have to have Setup Table in order to load transaction Data otherwise you will lock the Application Tables. Where am I going wrong im my thinking please?
Generic datasource nothing but we extracting data directly from the database table without any interface between the application/systems
4. What are steps in terms of IP before, under and after Delta Initialization. I belive that you can do two ways:
Full Update - Initialize Delta Process (without Data Transfer) u2013 Delta Update or
Initialize Delta Process (with Data Transfer) u2013 Delta Update
Am I right? What is most common method and why?
Correct
5. If you want to add a filed in Data Source after 6 month using it, you want to do it without re-init Delta Queue. You add field in RSA6, then provide info for ABAP to populate new filed (info u2013 name of Data Source, Extract Structure, field added, name of Application Table which contains the field). How does it work now as there is no SetUp table it has been deleted after Initialisation? How does Delta Queue know that it is going to receive data which has been expanded by one field or it may does not need to know at all?
Once you add the new field to structure(DS) you will get the data as on date onwards not historical data hence what is the concept of setup table ( delta records come from the Delta Que not from the setup table )
If you want histaric data to new field then you need to setp table deletion ...etc...
Hope it is clear..

Satya

Transport of Delta Initializations in SAP BPC 10

Hi All,
I have created "Delta Initialization" in Organize Delta Initialization in BPC Development system. While running the corresponding Data manager package for Delta loads, I have selected the Delta Initialization created and everything is working fine.
Now I need to transport the "Delta Initialization" created in Development system to other environments (For Example, Quality System). But I did not find the Delta Initialization created in Development system during transports. Is there any way I could select these objects (Delta Initialization) during transports?
Please help me in finding the solution for this issue.
Thanks & Regards,
Ramesh.

Hi,
This means that Package Links calling Delta Initialization also have to be recreated in every other environment ? There is still a lot a manual actions to do when transporting a BPC NW application ; integration with NW Transport System is still not complete...
Thanks & Regards,
Vincent

How to catch Delta Initialization and Delta Update in a Function Module

Hi Experts:
I'm developing a FM to extract data from R3. I wonder if anybody knows how to catch when i'm making a delta initialization and a delta update in my FM, because i have different parameters and routines from each one.
Thanks in advanced.
Points for helpfull answers.

Hi,
Keep one dummy date field in the structure. Make this dummy date field as delta enabled field. When you do Init load this date field value will be blank and next time when you do load it will have the last upload (in this case init load) date. You have to write a code before open cursor as below:
      LOOP AT s_s_if-t_select INTO l_s_select.
                              WHERE fieldnm = '(dummy date field name)'.
         l_date = l_s_select-low.
      ENDLOOP.
l_date will have the last upload date. This you can use to select the delta records from the table or for the further processing.
If you want to check the value during Init or delta load, go to RSA3 and debug it(Don't use F - Full load. Use I or D in the update field).
Hope this helps.

How to Use Early Delta Initialization

Hi BW Experts,
We are in BI 7.0 Version. Only for Reporting we are using BI 7.0. For modeling, still we are using BW 3.1C only.
We want to use Early Delta Initialization. But this is in Disable Mode in our system
I am getting the following Messages:
"Extractors supporting early delta initialization are not available before plug-in (-A) 2002.1"
"You cannot execute an initialization simulation together with an early delta"
Please can anyone give me the suggestion.
Regards
Anjali

Hi,
you have the option of writing the data into the delta queue or into the delta tables for the application during the initialization request in the source system. This means that you are able to execute the initialization of the delta process (the init request), without having to stop the updating of data in the source system. You can only execute an early delta initialization if the DataSource extractor called in the source system with this data request supports this..Use the Early Delta Initialization indicator in the InfoPackage if you want to avoid a period when no updates can be made (no document processing and update) in the source system while the delta process is being initialized. In some applications (such as LO Cockpit), an update-free period is nevertheless needed to fill the setup tables. In such cases, the update-free time is merely reduced. If you want to carry out early delta initialization, the update in the source system can continue and the data can be written to the delta queue while the initialization requests are being processed. Note: DataSources that support early delta initialization are available as of the release Plug-In 2002.1. The field ZDD_ABLE (characteristic value = X) for table RSOLTPSOURCE (in BW) or ROOSOURCE (in the source system) indicates whether a DataSource can support early delta initialization.Not always on our systems an important downtime is possible in the initialization process during the reconstruction and the delta init request (just thinking when you need to ask a billing stop period...a real nightmare in some company !)
For this reason, as of PI 2002.1 and BW Release 3.0B, you can use the early delta initialization to perform the initialization for selected datasources (just checking in infopackage update mode tab if this function is available): in this way you can readmit document postings in the OLTP system as early as possible during the initialization procedure..In fact, if an early delta initialization infopackage was started in BW, data may be written immediately to the delta queue.
But, if you are working with the queued delta method, using early delta initialization function doesnt make sense: as described before, its the same method definition that permits to reduce downtime phase.
But leaving aside that, dont forget that, regardless of the update method selected, its ALWAYS necessary to stop any document postings (for the relevant application) during setup tables recompilation run

BW early delta initialization request failed

Dear all,
the early delta initialization request of a info package failed for the data source 2LIS_11_VAITM & 2LIS_18_I3OPER due to disk space problems (log overflow).
Is there a possibility to rerun the early delta initialization load without destroying the delta queue and without a new source system initialization? The job has to been already scheduled to push the data into delta queue and the delta info package was not started jet.

When are init entries done in source system?And early delta initialization?

Hi Friends,
Q1) When are the init entries done in source system?
If INIT entries are done when I run INIT that means:
If my setup job finishes at 6AM and I run the INIT at 1 PM will I loose all data between 6AM and 1PM?
If INIT entries are done when I run setup table i.e. when setup table load finish then
If my setup job finishes at 6AM and I run the INIT at 1 PM...it will load data till 6AM
and after that data would bere there in Delta queue. So, this is ok...as no loss of data.
Q2) I have read on help.sap that "With early delta initialization, you have the option of writing the data into the
delta queue or into the delta tables for the application during the initialization request in the source
system. This means that you are able to execute the initialization of the delta process (the init request),
without having to stop the updating of data in the source system."
Does this mean when I run INIT at 1PM, no V1 updates will happen for that DS in Source System?
If Yes, that means I should always (when users are online) run INIT with early delta initialization
during times when users would be online?
Thanks!

You cannot run an initialization simulation together with an early delta initialization.
yes, it's available for logistics - oss note 505700, you can cross check the infopackage.
hope this helps.
505700-LBWE: New update methods as of PI 2002.1
g) Early delta initialization in the logistics extraction:
As of PI 2002.1 and BW Release 3.0B, you can use the early delta initialization to perform the delta initialization for selected DataSources.
Only the DataSources of applications 11, 12 and 13 support this procedure in the logistics extraction for PI 2002.1.
The early delta initialization is used to admit document postings in the OLTP system as early as possible during the initialization procedure. If an early delta initialization InfoPackage was started in BW, data may be written immediately to the delta queue of the central delta management.
When you use the "direct delta" update method in the logistics extraction, you do not have to wait for the successful conclusion of all delta Init requests in order to readmit document postings in the OLTP if you are using an early delta initialization.
When you use the "queued delta" update method, early delta initialization is essentially of no advantage because here, as with conventional initialization procedures, you can readmit document postings after successfully filling the setup tables, provided that you ensure that no data is transferred from the extraction queue to the delta queue, that is, an update collective run is not triggered until all of the delta init requests have been successfully posted.

EARLY DELTA INITIALIZATION IN LO COCKPIT

HI EVERYBODY,
SORRY FOR ASKING A SILLY QUESTION --BUT I REALLY NEED AN EXPLANAITION
WHAT IS EARLY DELTA INITIALIZATION????(can we select this method the same way we do for Delta init)
I KNOW THAT BEFORE DOING DELTA WE WILL DO DELTA INITIALIZATION.
I HAVE READ A WEBLOG OF ROBERTO IT WAS WONDERFUL BUT I GOT STUCK WITH THIS EARLY DELTA INITIALIZATION. AND ABOUT DOCUMENT POSTINGS.
DOES THIS MEAN THAT BEFORE GOING FOR DELTA INITIALIZATION (i mean before filling setup tables ) DO WE NEED TO SHUT DOWN THE INSTANCE ON OUR OLTP --so no transaction data will be updated to the extract structure.
WHAT IS FREE DOCUMENTS POSTING PHASE
THANKS AND REGARDS

Message was edited by: neelkamal moganti

You can find the option for Early Delta Init in the InfoPackage on the Update tab. Using this option, the source system update can continue and data can be written to the delta queue while the initialization request is being processed.
Early Delta Intialiation is the process in which we run the init of delta and load the delta queue in parallel.
Generally when we do Initialization we need to stop transactions in R/3 system till the initialization is completed if we do Early delta initialization we don't have to stop posting of transactions in R/3 even when we are doing initialization. Please see this for more explanation

Enabling Early Delta Initialization option for LO DataSource 2LIS_06_INV

Hi Guyz,

hi,
Not all Data sources support Early Delta Initialization. Early delta initialization is done to capture the deltas when the initialization is being done between BW and source system (init with data transfer). As init with data transfer takes large time and during this time any records created will also be not captured so we do early delta initialization, also the same can be achieved by executing the init without data transfer and then loading a full repair request. The init without data transfer creats a time stamp and delta is generated for newly posted records.

Arvind.

Need for locking system for delta initialization (BW-R3-LO)

Hello all,
Could someone please help me with the following,
Please be kind, don't get impatient for the lengthy post
1. Do we need to lock the system (or posting-free the system) to do early delta initialization or not? If yes, please explain me how that work?
2. Someone somewhere mentioned that early delta initialization is not preferable compared to normal delta initialization, even though early delta initialization is advantageous. Why is that so?
3. Imagine, while scheduling Queued Delta Init or un-serialized V3 delta Init, if I choose certain end date and time (say, 10pm, 12-31-2007) for the records, then all the records till that point would be loaded to setup tables and all the records after that point of time will be moved to extraction queue or update tables. My question is, if this is true why would we ever need to lock the system during setup tables filling?
    If you say the records after that particular time and date (10pm, 12-31-2007) will not be collected in extraction queue and update tables, why don't we do the following
             a). say, I do full load with end date and time (10pm 12-31-2007)
             b). Next, I do delta init with start date and time (10pm 12-31-2007) (this time I lock the postings)
         If we do this way, we can actually reduce the down time of the system. Is my conclusion right?
         If you say it's not practicable as some transactions' saving time differs from time stamp and some transactions' delta is even measured by pointer.......if this is the case we can use Delta offset. What do you say about this?
4. How this scenario differs to early delta initialization?
Your responses would be greatly appreciated
Thank you

This is applicable to Generic Delta where you can set the Safety Interval (Upper Limit and lower Limit) for the extractor based on ALE Pointer, or Time Stamp or Calendar day.
If you excute a extractor with early delta init, during the setup table fill, the delta records will be directly written to the delta queue. The delta management handles these functionality.

If you do a Init without Early Delta init, then the user cannot post new documents and you have to either schedule in the weekend or request for a Source System downtime.
But if you use Early delta , then you don't need the source system down time and the user can post new records during the init, which will be written to the delta queue directly.

Technical Content - Delta Initialization

Hi,
While loading the Technical Content data, Do I need to run the Transactions - Delta Initialization infopackages everytime before I run the delta info packages.
Please help.

Hi AHP,
I have executed both with text / without text infopackages for both 0TCTTQUERY & 0TCTQUERID.
I also checked the query by displaying key and name. Is is showing as #.
Post that I checked the Statistics cube. In cube some rows are blank without any query name, infocube name. But the frequency is having the value. May be because of this it is showing in the report.

There is no active Init to ur DS is in place. And hence u need to take an Init.
Try to maintain different IP's one is for the Init and other one is for the Delta.... the one in the PC will be holds good for the Delta..
Try create an Init IP if its not there already and then proceed with the load... if there is no data in the target data target as of now.....
If u have data on the target but some one has deleted the Init flag then u need to check whether all the requests has got posted to the target data target or not.. if not u need to take care of the action accordinly with the initi-Withoutdata transfer and then proceed with the Deltas...
thanks
Hope this helps
