How to do delta loading in BI?

Hai..
I sheduled the one job in the LBWE transaction. I deleted the contents of setup table and again filled the same and checked the data source in RSA3 and found data there. Then I replicated the data source in BI 7.0. After this thing How to perform delta loading in BI side.
As here we are using Infopackage for loading PSA alone.
1. <b>Where we do delta initialisation and delta load?</b>
2. <b>how the data is getting loaded in R/3 while doing delta update?</b>

Hi Methew,
After triggering V3 job from LBWE , go to Tcode RSA7 in r/3
You will find for your datasource some data packet are available in delta Queue.
Now you have to create a infopackage in BW for init
1)Go to left top of the infopackage click on Initialization of source system ( there should be no request) if you find any request delete it.
2)Click on update tab and select Initialization delta process.
3)Data selection would be in gray ( no selection)
4)Process can be any .
5)Select your data target.
6)Click on start button from schedule tab.
Once int is done create a new info package for delta .
1)Click on update tab and select delta updtes.
Hope this helps.

How to do delta load after full load

Hi,
I did full loads for my Data target.
I have 15 requests on my Data target.
Now i want to do delta load.
Please help me how to do delta load even after full loads.
Advance thanks.
Regards,
Rafi

Hi,
change in my post!!!
after full load you can go for delta,but it is not viceversa
if you want to run delta
since you have done prior full loads,,do init without data transfer which will sets the init flag
now run delta
please also check is your datasource supports delta or not
try RSA6, datasource and display,
check if 'delta update' is marked
or table ROOSOURCE field DELTA
Cheers,

How to set delta load in process chain

hello all
The scenario is i created process chain for transaction data and all the infopackages are in initial load now I want to do delta,how to set delta in process chain,bcoz only the new records should load?
kindly anyone let me know.
regards
balaji

Hi Balaji,
In most projects thay dont have the "init" infopackages in the process chain. They have 2 infopackages for a load - One for init and the other for delta. Now that you have created the process chain what I suggested was to change the infopackage settings to delta load and change the description of the infopackage.
The other option would be to create a new infopackages for delta and include them in the chain replacing the "init" ones.
Bye

Details about how to do delta load

Hi,
Can someone please give me the details about how to do delta from scratch. Like, i have the custom datasource created in the RSO2, created infosource in BW, loaded that into an ODS using full load. Now how do I do the delta for the same ods instead of full load. It will be a great help to me if you can give me the steps how to do and your help is always appreciated.
Thanks in advance,
Sue

Hi
Delta Process
Definition
The delta process is a feature of the extractor and specifies how data is to be transferred. As a DataSource attribute, it specifies how the DataSource data is passed on to the data target. From this you can derive, for example, for which data a DataSource is suited, and how the update and serialization are to be carried out.
Use
The type of delta process affects the update into a data target. When you update data in an ODS object, you need to serialize it so that you can also overwrite it. According to the delta process, the system decides whether it is necessary to serialize by request or by data packet.
Structure
There are various delta processes for SAP source systems:
1. Forming deltas with after, before and reverse images that are updated directly in the delta queue; an after image shows the status after the change, a before image the status before the change with a negative sign and the reverse image also shows the negative sign next to the record while indicating it for deletion. This serializes the delta packets. The delta process controls whether adding or overwriting is permitted. In this case, adding and overwriting are permitted. This process supports an update in an ODS object as well as in an InfoCube. (technical name of the delta process in the system): ABR)
2. The extractor delivers additive deltas that are serialized by request. This serialization is necessary since the extractor within a request delivers each key once, and otherwise changes in the non-key fields are not copied over correctly. It only supports the addition of fields. It supports an update in an ODS object as well as in an InfoCube. This delta process is used by LIS DataSources. (technical name of the delta process in the system): ADD)
3. Forming deltas with after image, which are updated directly in the delta queue. This serializes data by packet since the same key can be copied more than once within a request. It does not support the direct update of data in an InfoCube. An ODS object must always be in operation when you update data in an InfoCube. For numeric key figures, for example, this process only supports overwriting and not adding, otherwise incorrect results would come about. It is used in FI-AP/AR for transferring line items, while the variation of the process, where the extractor can also send records with the deletion flag, is used in this capacity in BBP. (technical name of the delta process in the system): AIM/AIMD)

How to do delta loading again based on delta init time?

Hi experts,
   in my case, I have delta init (2000 - 9999) which successed on 3.1 (it's huge data and time consuming) after that, we have delta loading per day.
   unfortunately, we do some wrong process when we get delta failed, it's cause some data missing in BW.
   3.5   delta success
   3.4   delta fail, do right delta correction (repeat delta)
   3.3   delta fail, do wrong delta correction
   3.2   delta success
   3.1   delta init success
   in this case, we miss some records in 3.3 's request. if I going to fix this problem, formal way it should do delta init again then schedule daily delta. but since delta init is successful and need lot of time.
can I advoid do delta init again?? just do delta again base on delta init (3.1) ??
   thanks in advanced

Hi jie,
Whenver you incur a Failure when data is being loaded from R/3 systems to BW via DELTA. It means that the Records were not transferred during that load to BW from R/3.
Hence the next load is always a REPEAT DELTA.
It may happen at times that you may miss few records in this.
If so, then in that case do a repair request from infopackage scheduler and then load the missed records.
Then again start off with Delta and loads should not have any problems.
Else you need to do a Re-Init of Delta. And re - do all over again.
Cause every time we miss the records we need to bring them in via repair request.
Hope this helps.
Thanks,
Pradip Parmar

How to do delta using aggregate ineed clear steps

how to do delta using aggregate ineed clear steps

Hi Deba,
If i understood your question corectly:- How to do delta loads to Aggregated Cube.
If yes then it is as normal as loading a delta load into a normal cube.
But only diff will be u need to roll up the cube that has aggregates after the sucessfull delta load.After u do the rollup only the data will be available for reporting.
Here u need to be carefull abt 1 thing is if the data volume grows up in the aggregated cube and if you want to compress the data then u can do it for the Rolled up data only.
Aggregates acts on F-Fact Table & Compression Acts on E-Facttable.
So in process Rollup comes first and Cube Compression will be second. Here we have an option of Compressing the rolled up data in Aggregates this is diff from Cube compression.
Best Regards,
VNK.

Stop delta loads in R3

how to stop delta loads from R3

Hi,
if u want stop loads for particular application (11,12,13) like that stop V3 jobs
in LBWE try with job control
or
if u want to stop load particulre data source select the job in SM37
Job----->delete
if u want to stop load temp.
Goto TC SM 37 job overview
Select the job (Use LIS)
Get job details PID number
In SM50 find the PID number
In menu cancel without core
in this case u can recover the delta resechduling ot "V3" jobs.

How to set-up a Timestamp for BI Delta Load in 0CLM_INVOICE datasrc at R/3?

Hi Experts,
Kindly let me know How to set-up a Timestamp for BI delta load at R/3 for the Data source 0CLM_INVOICE ?
Since the Timestamp for Upload of BI Delta is " . . : : ", we are not getting any delta value to BW.
I would like to know in where we need to maintain the DATE & TIME to fix the above problem.
Thanks.
Regards,
Jayaprakash J

Dear Jayprakash,
Chech the below links, it may help you in your case :
Re: 0FI_AA_11 Delta load failure
http://wiki.sdn.sap.com/wiki/display/BI/GeneralErrorIn+BI
Actaully you need not have to maintain the timestamp. Just try to replicate your datasource and the try to load the delta again.
Hopefully it will work.

In BI 7 how do we handle if any delta load gets fails

Hello All
Iam having a doubt like,in BW 3.5 if we are loading delta data from one source ODS to 2 targets(either cube or ODS),and if for one target if the load gets failed we will delete the bad request from the 2 target ods , reomve datamart flag from source ods and then relaod the delta load again.
But in BI 7 how do we handle this type of scenarios.
Many Thanks
Swami

In 7.0 we have DTP between one source and one target right?
If a load fails then delete the concerned request and reload.
It is independent of the other load.

How to handle the error delta load?

Hi Experts,
We have a InfoCube include three InfoSource: 2LIS_11_VAITM, 2LIS_12_VCITM, 2LIS_13_VDITM.
The delta load of 2LIS_12_VCITM failed on Oct 23,2006. It blocked all of the latter data load, even though 2LIS_11_VATIM and 2LIS_13_VDITM load the data successfully. And 2LIS_12_VCITM didn't do any load step after Oct 23, 2006.
How should I do to fix this problem and make all of the data can be go into InfoCube correctly?
Thanks,
Lena

Hi Jerome,
Thanks so much for you help. Currently, the data loaded successfully.
But I have another issue, because of the failed request status is red, it seems it blocked all of data to go into InfoCube (even though the delta load is successful). I can not see the new data in the InfoCube. And in the InfoCube manage, the "Request for Reporting Available" field for the successful request is null.
How should I do?
Thanks,
Lena

How should I reload the delta load?

Dear all,
An ODS which includes Sales invoice information with daily delta load. The loading is fine but somehow one KF got different logic from April e.g. for same order this KF has correct value after April but incorrect value before April. So I am going to reload data old than April, but all the old load are fine and existed, so how should I do?
Thanks

Hi,
Thanks for you reply, No date for selection. So I found some data in the ODS for a specific comany code and the bill type(I got 16 recordes), then I created a Infopackage then put the selection same with the company code and bill type, set it to full load and run immediatly, but 0 record was loaded. I am sure the corresponding data exist in R3 because I checked the data using VA03. So what's the problem?
Thanks in advance

How to achieve an image loading affect?

Hello,
Before you continue, take note that this affect only seems to work in Mozilla Firefox and Google Chrome -
Website Link : http://boinx.com/
[Should work with most images on the website]
I am a web designer and when browsing the internet, I noticed this affect. When I visited a page on their website, I noticed that wenever an image first loads, It is shown as a matrix of squares that shrink/un - blur to the normal resolution of the image.
[Above Image] Look to the bottom of the image and you will see something like a pixelated image . . .
As The image continue to load, it looked like the rest of the above image . . .
Here you see the fully loaded image [Above Image]
Can you tell me how to achieve and control this affect?

Hi There:
I don't think it is any effect.
The images used on the home page as the main graphics are all JPG images and they must be saved for progressive download when created. For example you can save an image in Photoshop and choose progressive as one of the option while saving.
Progressive download basically implies that images are downloaded pixel by pixel so that user feel something is happening (instead of downloading the whole image in one go which can take time).
To know more on this please refer to links below:

How to Achieve this Data Load into Cube

Hi Experts,
Could you please update me on how to achieve this
I got a History data (25-35 Million Records) for about 8 years to be loaded to BW.
What is the best approach to be followed
1) Load everything into one cube and create aggregates or
2) Create 4 different cubes (with same data model) and load load 2 years of data into each cune (2Years * 4 Cubes = 8 Years Data) and develop a multicube on top of 4 cubes
If so how can i load data into respective cubes
Ex: Lets assure i got data from 31.12.2007 to 01.01.2000 which is 8 years of data
Now i created 4 Cubes--C1,C2,C3,C4 & C5
How can i specifically
load data from 01.01.2000 to 31.12.2001 (2 Years) to C1
load data from 01.01.2002 to 31.12.2003 (2 Years) to C2
load data from 01.01.2004 to 31.12.2005 (2 Years) to C3
load data from 01.01.2006 to 31.12.2007 (2 Years) to C4
load data from 01.01.2008 to 31.12.2010 (2 Years) to C5 (Currently Loading)
Please advise the best approach to be followed and why
Thanks

If you already have the cube C5 being loaded and the reports are based on this cube, then if you donot want to create additional reports, you can go ahead and load the history data into this cube C5.
What is your sourcesystem and datasource?. Are there selection conditions (in your infopackage) available to specify the selections? If so, you can go ahead and do full loads to the current cube.
For query performance, you can create aggregates on this cube based on the fiscal period / month / year ( whichever infoobject is used in the reports)
If your reports are not based on timeperiod, then multicube query will work as parrallelized sub queries and so there will be 4 dialog processes occupied on your BW system everytime the query is hit.
Also any changes that you want to make in cube will have to be copied to all cubes, so maintenance may be a question.
If there are enough justification, then approach 2 can be taken up
