Full upload then delta?

Hi all,
We have a scenario where the ODS object contains 2 billion records.
we want to load this data in to new cubes.
Since we have huge data:
-can we go for delta init and then subsequent deltas?
-Can we go for a full load (by time selections in the infopackage) and then can we define a delta?
What would be the ideal solution since ODS contains 2 billion rec
Regards
Naveen

Hi Bhanu
Let me know weather I am right:
1. I create a info package and run with the option Init with out data transfer
2. Create several infopackages with selection options (based on time) and run with repair requests
eg if i have data from 2005 - till date then I create 5 infopackages. the first 4 info packages are restricted each for 3 months and the 5 or last info package for 2006-tilldate
After al these jobs
Now I create a new infopaackage with delta loads for future data ?
Let me know ny suggestions
Best Regards
Naveen

Generic Delta: Init, Full Upload and Deltas...

Dear All,
Last week on 10.04.2014 I've created "Generic DataSource with Generic Delta" and used CalDay as Delta-Specific Field and lower limit kept to blank and upper limit to 1. On 11.04.2014 I've initialized the Delta with Data Transfer using Process Chain: Time 1:15 p.m (Note: Posting was on)
see below screen shot:
Result: Process Chain was scheduled to immediate and it executed and initialized the delta and brought records as well. See below screen shot of RSA7:
Q: 1: Why generic delta current status is 10.04.2014, as I'v scheduled delta through process chain on 11.04.2014 @ 20:50: and why Total column is showing 0 records? Even I've checked Display Data Entries with Delta Repetition, but could not find any records?
Following is the InfoPackages which I created for Delta Loads and used in another Process Chain for Delta scheduled (daily @ 20: 50).
Following is the DTP used into Delta Process Chain:
On 12/04/2014 when I checked my InfoCube, and found that same number of records being loaded again despite InfoPackage and DTP were created as Delta, see screen shot:
On 12/04/2014 See below PSA table:
On 14/04/2014 when I checked InfoCube and I saw deltas being loaded successfully: see below screen shot:
On 14/04/2014 see below PSA table:
On 14/04/2014 see below RSA7 BW Delta Queue Maintenance screen shot:
Q: 2: Why am I unable to load the Delta records on the day(11/04/2014) when I initialized it with Data and why same number of records being loaded again on 11/04/2014?
Q: 3: On 11/04/2014, around 1:15 p.m I've initialized Delta with Data successfully and the same day (11/04/2014) was my first load of delta records (Time: 20: 50), could this be a problem? as the posting period was on when I initialized and I tried to load the delta on the same day?
Q: 4: Why the pointer is showing me Current Status: 12/04/2014 today and this time around I can find last delta records from "Display Data" option with Delta Repetition?
Q: 5: Have I missed something in the design or data flow?
Q: 6: How can I verify deltas records accuracy on daily basis; is it from RSA3?
or How can I verify daily deltas with ECC delta records?
Q: 7: What is the best practice when you load full data and initialized delta and schedule deltas for Generic DataSources with CalDay as delta specific field?
I will appreciate your replies.
Many Thanks!!!
Tariq Ashraf

I clearly got ur point.....But
If i have situation like ....." I loaded the LO data from R/3 with Init delta......then i loaded 5 loads of delta too.......due to some error in data now i am trying to load all th data......In this case if i do Full upload it is going to bring all the data till 5 th delta load .......If i do Init delta again it is going to bring the same data as full upload..........In LO while loading both Full load or delta init load we need to lock R/3 users....I believe we can load delta even after full upload by using "Init delta without data transfer"............So that wont be the barrier....then what is the difference or how should i figure out which load should i do.............If i am wrong please correct me.......
Thanks

Delta upload full upload

Hi Gurus,
In ODS already delta is loading every half an hour. But, I don't see any data for one field in ODS. In that case, I want to load the data again to see if i can get the data? how can i do a full upload while delta is enabled? do i need to stop this delta and enable the full upload? or just full upload?
any help appreciated.
thanks

hi S.K.B,
i guess you enhanced business content datasource,
yes you need to populate the new added field in r/3
via user exit zxrsau01 (transaction data), take a look

Full Repair/Init/Delta & LO Cockpit Information required

Hello
I'm pretty new to BW and I'm starting to dig a bit more now into the deeper stuff now. I've created Cubes with Extractor from R/3 and now I'm interested to understand more the LO Cockpit various specificities.
For a better understanding, let's establish a scenario as --> Activation of R/3 SD Billing --> BW --> DSO --> Info Cube
Ok, first, let me start by explaining what my understanding is.
First, I need to go into R/3, t-code LBWE, and under the "13: SD Billing BW", activate the extractors I'm interested in (Header & Item as an example in my scenario). I'm also assuming that the default fields within the extractors are suiting my needs so no adjustments needed for now. I should also schedule a job here that will create records in the Waiting Queue on a daily basis.
Next, I need to fill the setup tables from the t-code SBIW; I enter a date in the future, it runs for a while, then I get my data prepared. In the setup table, it included all the existing R/3 invoices as of now right? (1) Let's say there are new invoices created minutes after I've created the setup table, they will be sent to the Waiting Queue as soon as the document are created or will the schedule job created earlier will post them to that Queue? (2) If the job send them to the Waiting Queue, where are sitting the pending documents before being sent then? (3)
Now, on my BW system, once the Data Source have been replicated, what do I need to create and execute to be able to proceed with a Delta process? (4) I know I have to create a u201CInitu201D package 1st but have no clue why except that itu2019s needed for me to be able to create a u201CDeltau201D package afterwards. Technically, what does the u201CInitu201D package really does? (5) What is the reason to have a u201CInit without datau201D and u201CInit with datau201D, I mean, I know literally what it means but again, why would I choose one over the other? (6)
Iu2019d also like to understand the concept behind a "Full Repair" request, which I have no clue what the purpose is. I guess there some of these properties (Full Repair, Init) determines where to get the data on the R/3 side; Setup Tables or Waiting Queue? (7)
Please, provide clear respond (Donu2019t assume I know what youu2019re think of ) on my questions (identified by a bold number) and don't hesitate to provide a long one if needed to; it's better to provide more information than not enough
Thank you in advance for all of your help!
P.s. I'm working with BI 7.0.

Hi.....
So if I understand properly, whenever I run the init, it toggle a flag on my source system (R/3) which means that all changes performed in the invoices are going to be sent in the Delta Queue? Until I run an Init, changes are not written anywhere (Other than internal SAP tables/structures required by R/3 Invoices processes).
If so, does this means that I could loose some transactions from the time I run the creation of the setup tables and the time I execute the Init on my BW system? Let's say I create the setup table today and execute the init only tomorrow; all invoices that have been created by this time won't be tranferred to BW?
yes,suppose you create a set up table today....and ron the init tomorrow........in between many new recordsmay come.......but those new records will not be in the set up table.......since those transaction happenned after the filling of the set up table........and new records only goes to Delta queue after you run the init.......
I have to admit that it's hard for me to "Suppose" i did not want to do an init; what would be a good reason not to? I understand that both Init types will toggle the "Init" flag on but still can't figure appropriate business scenarios for both types
Suppose your Delta mechanism is corrupted.......for which you need to do a full repair......I mean first ,you have to delete the existing init flag.........second, you will fill the set up table .......third,you will load the records by Full repair......then 4th step will be running init without data transfer..only to set the init flag..........it will not pick any records.............then delta.......
Init with data transfer picks all the previous records......we cannot give any selection..............for selection we have to use Full repair.........then init without data transfer..............generally for Transaction data we will go for Full repair..........bcoz otherwise number of recordswill be very huge........and there may be duplicate records..................
Another thing we want to say........we do full repair we mainly use for ODS.........it is just like Full upload.........in case of infocube we can use full upload instead of full repair.........but in case of ODS full repair is must............since ODS does'nt support Full upload and Delta upload parallely........otehrwise ODS activation will fail........
Then again you hav to use the Program : RSSM_SET_REPAIR_FULL_FLAG to convert full upload request to full repair request.....
Hope this helps....

Debjani.......

Change load full data to Delta

Hi!!
In the past, we load Full data for a customized DataSourece. Now I changed the DataSource to load delta datas.
This data source was connected a ODS and when I tried to initialize delta process I received the error message. "Full updates already available in ODS 0SAL_DS01 ; Cannot update init./delta".
Someone know, How can I Initialize Delta Process?
Regards,
Cesar G. Batista

Hi.............
ODS does'nt support Full upload and delta upload parallely..........suppose a ODS is getting loaded with delta upload...........then if u do a full upload.........then ODS activation will with this error...........then u have to convert full upload to full repair...........
Go to SE38 >> Program : RSSM_SET_REPAIR_FULL_FLAG...................this program also exists in 3.5.............check it properly............
Check SAP note 689964 ........
Hope this helps........

Delta Upload - InfoCube Then Full Upload ODS

Hello,
1. I upload a InfoCube in Delta Mode.
2. I upload form this InfoCube to a ODS in Full Mode.
Exemple :
1. InfoCube (Upload in Delta Mode) :
Request Order Operation WorkCenter Values
1       10    1         AAA         +10
2       10    1         AAA         -10
2       10    1         BBB         +20
2. ODS (Upload from the cube above in Full Mode)
Order(key) Operation(key) WorkCenter Values
10         1              AAA        -10
The last record upload in my ODS is the second of the Infocube. The data in my ODS are incorrects. I don't know if I need to use 0RECORDMODE.
Thanks in advance for your help.
Stéphane

Hello Stephane,
In your scenario, please do either one from following in order to update date correctly in ODS from infocube,
1. Change the update type to an addition from an overwrite at ODS level.
2. or use serialized V3 update at the r/3 side, so that R/3 system sends changed records in the same sequence as it was generated. Because you might be getting +20 first then -10 and ODS setting is kept overwrite. As a result, the ODS data are incorrect(-10).
Hope it helps you.
Thanks and Regards,
~Ketan Patel.

Full upload misses records while delta brings them

Hi experts,
I'm using 2LIS_12_VCHDR extractor and with delta exctractions everything is worknig correct. The problem comes when I want to make a full upload. It is not taking the last records (while delta took them). It is not bringing records into BW since the exact day I reloaded the 12 LIS tables.
If I create a sales order, and this order is delivered, my delta infopackage brings it into BW, but my full infopackage is not bringing it.
Any clues?
Points will be given,
Thanks

My scenario is the next one for 2LIS_12_VCHDR:
- Full upload on Nov 13th (6 months ago) and it takes 170103 records.
- I make another full upload today and I obtain 107103 records (the same as 6 months ago, and there are a lot more).
- I make an init request > I create a delivery in ECC> I make a delta upload an it takes it.
- Then I make a full upload and it is not taking it. I still have 170103 records.
Do I have to reiniciate the 2LIS_12 in ECC (OLI8BW)?
In the other hand I have the 2LIS_12_VAITM working with delta every day. How it will affect to this extractor if I reiniciate all the 2LIS_12? I'm going to miss data? I'm going to duplicate data?
Thanks

I am running full upload daily now i want to load delta records how can i

Hi Gurus,
I am running full upload daily now i want to load delta records how can i do that could any body help recording this..

Kiran Kumar

Hello Kiran,
First make sure that you datasource is delta enabled. If so create a new infopackage for Init without data transfer and execute it. Then create a InfoPackage for Delta.

ODS optioin- Is it going to be full upload or init delta?

Hi frnds,
I got a query where the scenerio goes like this,
Data loading from ods to infocube. Let us suppose in ods settings, i have selected the option Update data targets from ODS object automatically. Then my question is whether it will be a init delta or full upload.....please explain the scenerio.
thanks in advance
regards,
dubbu.

Hi Vinit,
This will be dependent to the load in ODS,
if the load is init in ods the further upload will be init.
If the load to ods is delta the further upload will be delta

- Differences between delta and full uploads of transactional data

Hi All,
This is with refrence to the loading transactional data into the cube.
I know that delta and full uploads of transactional data into the cube is done for the following reasons.
1. Delta upload allows change in transactional data (add/delete/modify) for the particular period selected but this is not the same in full upload.
2. Full upload takes less time compared to delta upload for the particular period.
Please let me know whether my understanding is correct. Otherwise, please explain these two concepts with examples taking loading transactional data into the cube.
Regards,
Ningaraju

hi,
full upload is done to avoid more time to load the data .if u use initilallization then it will take more time to laod the same amount of data when compared to full load.
however your statement about the delta is correct.
u can perform delta only after sucessful initiallization.
so
1.first full load(to avoid more time0
2. inirtilallization with zero recored.
3. delta

Deltas and full upload

Hi all,
Let's say we have a scenario like this.
For document number 1001 and document item number 10,
the order quantity was 200 initially. This was transferred to infocube. Now, the order quantity changed to 180. I assume that in a delta upload, -20 will be transferred to the cube. But, for full-upload what value gets transferred to BW. Is it 180? If so, how does these values get tallied? I mean, 200+180=380. What really happens here?

hi Pooja,
initialize in infocube
doc no doc item order quantity
1001   10       200
change to 180 in delta upload, records in infocube will be
doc no doc item order quantity
1001   10       200
1001   10       -200
1001   10       180   (value in report = 180)
full upload
1001   10       200
1001   10       180 (value in report = 380)
hope this helps.

Full Upload

Hi Experts,
Would like to seek assistance on this...
In the case of full upload to info providers what is the normal loading strategy?
Is it always delete the existing records[requests] before loading the records again.
I know delta is very straight forward that after initialization next step delta update takes care..
Pls advise.
Alok

Hi,
The stratagy depends on your data model and the type of data you are extracting.
If you are using ODS as a staging layer in BW, you need not delete the previous request.
If you are using any selections in info packages you need not delete the previouos full load request.
If you are not using any selections in info package and updating the info cubes, and the data contains some previously loaded records then you need to delete the previous request.
Hope this helps.

Full repair or Delta Init?

Hi Experts
I need your suggest
a)
Sometime we need made a re-load one month, and Im using a 'full repair'; but this give me errors (duplicate or missing records) where users are working in R/3 at the same time. Other posibilite is a 'full load' + 'delta init with out records'. Which is better in this case?
b) People say than after use a 'full load' you lose the init flag and is necessary made a init again.
In this case a made a 'full load' for 001.2008, and 'full repair' for 002.2008; and the init flag / delta load seemed ok. Is this possible?
c) When use a 'full repair', (with selection scope = 001.2008), how does it work? read from R/3 again or repeat the delta loads for the month specified in the selection, in the infopackage?
Thank you in advance!!

Full vs. Delta Load

Hi BI-Experts!
This is a rather general question.
Is there a recommendation when to use Full or Delta Load?
I know the functional differences but do SAP or some technical reasons say that each of them may only be used in special cases?
For example Delta Load can only be used with SAP source systems?
Best regards,
Philipp

Hi Philipp,
This is a pretty open-ended question. I will give you a few examples of when I use each ....
Delta's:
1.) If the record set is large and changes a lot daily. If you have a large initial load, let's say 2Million records and you get about 200k records per month, then you want to use a delta mechanism. There are just too many records to reload daily.
2.) If the record set is wide (many fields instead of a few), it will take less load time to run a delta than a full load.
3.) Datasource restrictions....some business content datasources don't have full loads and vice versa (some don't have deltas).
4.) Do my loads take too long? If so, I will convert full loads to delta's to shave off time here and there.
Full
1.) I gauge this mainly based on load time. If it takes 5 minutes to load 100k records, then it's going to take longer to figure out what delta's were missed (if there was a problem) than it would to just reload the dataset.
2.) Do my requirements dictate that I need to drop and reload the dataset? The best example of this would be the current year's forecast. Some companies revise the forecast and don't want to keep any previous revisions.
3.) Some data loads load a snapshot of a specific date. So, if I wanted to take a snapshot of inventory in a DSO/ODS on Monday, I would Datamart it into a Cube doing a full load for Monday's date.
Hope it helps!
Thanks,
Brian

Datamart full Upload

Hi all,
FIGL , Inventory cubes loading with delta records in BI, whenever loading same data into SEM but it is not loading with delta, every time doing full upload only, but those cubes having huge data so it is impact on load , even i did init w/o after full upload but its not loading for delta, every time its loading the whole data from the both cubes. pl suggest me to do delta.
Thanks
Pinky

Hi Pinky,
Could you check your info packages update tab strip whether it is in delta package or init package
Thanks,
