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.

Enabling Early Delta Initialization option for LO DataSource 2LIS_06_INV

Hi Guyz,
I want to enable Earlt Delta Initialization option for LO DataSource 2LIS_06_INV, as of now its greyed out.
please tell me if its possible or not, and if yes then please let me know the steps in detail.
cheerz,

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.

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!

Hello,
You will find the answers to the questions that you ask and the correct procedure to follow in the SAP note 602260.

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

Hello Gurus,
What are the scenarios we use Early Delta Init.
Is it available for Logistics datasources.
Full points to right answers.
Thanks in advance.

Extractors that support early delta initialization were delivered with Plug-Ins as of Plug-In (-A) 2002.1.
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

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

HELP: 0 from 0 records: Initialization Option of source system

I executed an 'Initialization option for source system' on the scheduler and no data is coming from the source system.
Steps taken:
1. Delete data from target DSO
2. Picked InfoPackage and selected it returns back 'Initialization option for source system' on the scheduler
3. Deleted the initialization setting
4. Executed InfoPackage
Result: "0 from 0 records" found. How do I fill the queue table in the source system if not records are available? T
5. I go to delete the request in the PSA to retry: "No data in the PSA".
This is to resolve a HIGH status ticket because I stopped delta process of other Infoproviders until this situation is resolved.
Can you provide detail steps to properly create a trigger delta data from R/3 from a "Initialization Option of source system". We have cancelled delta undates until this is resolved.

Hi
Now that you have run the init once, there is no need to delete the init flag
The delta pointer is set now, you can run the delta Ip from now onwards.
But if there were already some previous deltas done for this, and the delta had failed, because of which you have to initialise the delta again, then you need to delete the previous initialisation.
To delete the init flag.
Open your delta IP in RSA1(or in the PC)
Goto the scheduler menu option
initialization option for source system
There you will see that a window will pop up which will show a succesful load, and you will see a tick mark in the first column.
If you see a cross mark that would mean that the initialization has failed.
this mark whihc you see is called the init flag.
If you need to reinitialize the delta, then you have to delete this .
Select the entire row and click the third button at the bottom.
This will delete the initialization for source system( i.e init flag)
now, before running the delta, you have to run the init IP again.
it depends on the scenario whether you hav to run with data transfer or without data transfer.
Hope this clarifies the query

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.

Initialization Flags deleted from Initialization options for Source System

Hi BW Experts,
We have loaded PCA data in Infocube last week with Fiscal Year/Period Selection Parameters like
001.2004 to 016.2004
001.2005 to 016.2005
001.2006 to 016.2006
001.2007 to 016.2050
So we got 4 Initialization flags in Initialization options for Source System in SCHEDULER.
After this we are running Deltas daily
Accidentally All Initialization Flags deleted from SCHEDULER yesterday that we did not know yesterday.
Deltas did not run today.
Please can anyone tell me the solution for this.
I have to run the Delta today. How can i get the yesterday records in my Data Target,
Thanks & Regards,
Anjali

Hi Anjali,
Please delete the Init Request from your data target performed for Selection 001.2007 to 2050.
Also delete only those deltas request from your Data target which were performed after the above mentioned Init.
And then Re-Init with Selections on Fiscper - 001.2007 to 2050.
Thanks

Can I delete 'Initialization Options for Source System' in Process Chain?

Hi All,
Can I automate the process of deleting the 'Initialization Options for Source System' for Delta Init package? I need to include this step in a process chain, rather than deleting the init request manually.
Thanks,
Naveen.

Naveen,
As far as I know, nope. And it's logical, considering the Initialization is a "one time" process and not a repetitive one (unless you have to reinitialize, of course...)

Luis

Early delta initialization and update methods

Hi gurus
Can we use EDI with "queued delta" as update method?
If yes where we need to do that setting and if no then would you pl tell me which functionality we need to use in infopkg to load delta from R/3 with Queued delta as a update method?
Pl help to understand this.
Thanks

In the 'update' mode in your infopackage, if you see an 'early delta init' option, you can use it for that datasource (for queued or any other delta). This is where you choose to run an 'early delta init'.

Initialization option for source system in schedular tab

SAP BW Gurus:
Please help me with this question.
This is a new system setup. I used initilization option doing the two years of data loads. I loaded eight loads with each load for a quarter's data.
Then I found there are some loading issues with one load. So, I need to delete that load and reload again.
To do that, i need to delete that particular load in the initialization request.
When I highlighted that request and delete, there is a window pop up saying:" There are active init selections in source system for this data source. Therefore, only ALL init selections can be deleted at once."
If I choose "no", I couldn't delete that particular package. Then, just for the sake of trying, I click on "yes", then all the 8 initization requests are gone!!!
Now, I got two questions:
1. If all the requests are gone, does it mean, I have reload everything again for initilization, ?? (it will take days to do it!!) Now i have two years of data already in my cube and DSO. This is version 7. But I do need to schedule Delta process later.
2. If I have eight requests, am I able to delete only one of them?? What does the question i listed above mean?
Thanks so much, guys!!

Hi,
System maintains only one delta queue for a datasource irrespective of ...number of inits... which is done from the source system to the target system and this you can see in RSA7.
You can do init with data for any number number of selections but the delta for all those selections will be combined and will present in one queue.
If you delete one init request it will delete the whole delta queue as all these request share the same delta queue and therefore all the init selections will go off.
You should be careful when you do this.
Now since all the delta is lost and if you can find a way to load the lost delta like doing a full repair on created on or changed on date... then you can just as suggested...but on the safer side I would suggest to the repeat the process or as mentioned in the OSS notes.
Thanks

Initialization options for source system (message_type_x)

Hi All
My R3 source system is just connected to my BI, after the upgrade of R3. Now i saw in RSA7, all entries in RED. So i have deleted them manually in RSA7.
Now, in RSA1, I wanted to run the Init delta IPAKs for all those deleted datasources, when i open the IPAK to run, its giving me MESSAGE_TYPE_X dump. So i cant go to the menu --> scheduler --> initialisation options for IPAK.
I think i should have deleted from here than in RSA7 in R3. But now i cant even open the IPAK. The module name in the dump is RSM1_CHECK_FOR_DELTAUPD.
How can i resolve this issue ? Do i have to replicate the datasource in RSA1 as Source system is upgraded ( we actually replicated all metadata by rt clicking the source system).
Any help pls ?
thx

Best practice to reduce downtime for fulllaod in Production system

Hi Guys ,
we have options like "Initialize without data transfer ", Initialization with data transfer"
To reduce downtime of production system for load setup tables , first I will trigger info package for Initialization without data transfer so that pointer will be set on table , from that point onwards any record added as delta record , I will trigger Info package for Delta , to get delta records in BW , once delta successful, I will trigger info package for the repair full request to get all historical data into setup tables , so that downtime of production system will be reduced.
Please let me know your thoughts and correct me if I am wrong .
Please let me know about "Early delta Initialization" option .
Kind regards.
hari

Hi,
You got some wrong information.
Info pack - just loads data from setup tables to PSA only.
Setup tables - need to fill by manual by using related t codes.
Assuming as your using LO Data source.
In this case source system lock is mandatory. other wise you need to go with early delta init option.
Early delta init - its useful to load data into bw without down time at source.
Means at same time it set delta pointer and will load into as your settings(init with or without).
if source system not able lock as per client needs then better to go with early delta init options.
Thanks
