Hi Gurus
give me the detail informatio about ,
1)Full , init , delat
in init we have some options , and also in DTP WE dont have init . plz give me the detail formation about
these things and in which scenario we go for these , and in 3.5 and 7.0
thanks in advance

Hi,
Go to the infosource tab in the RSA1 and search for 8(your infocube technical name).
Eg: if your source infocube 0tct_01 then search for 80tct_c01.
Create an infopackage on the 8.* ICtechnical name and schedule the load. This will load data from your source IC to Target IC.
If it is not clear please let me know.
Thanks

Delta with reversal into cube from LO extractors

Hi SDN,
In our LO extraction design we have write-optimized DSO used as EDW as the first layer in BI. Then data is sent to Business Content infocubes, such as 0PUR_C01 though we are using their copies and instead of Update Rules/Transfer Rules, we are using PSA, Transformation, Write Optimized DSO, another transformation and onto the cube. DS and all other objects in the data flow are BI 7.
What we are not clear about is the role or ROCANCEL when passed to both STORNO and RECORDMODE and its impact on the cube after the write-optimized DSO. Some key figures are reversed for 'R' but others are not.
We had thought that 2LIS_02_ITM via a Write Optimized DSO will pass on STORNO and RECORDMODE to the cube which should have reversed all key figures in the cube if the value is 'R'. But it is not happening. Whatever key figures were reversed in the source system, they remained reversed, others are still there and adding another row in the cube with some positive values.
Can anyone shed light on this or provide reference to documentation regarding delta processing in the cube, especially from LO extractors like 2LIS_02_ITM, etc.?
Thanks
SM

Friends,
Thanks for the reply.
My question is more fundamental.
In 3.5 There was expected to be no DSO between Source system and the cube. How were the Update, add and delete handled then?
As I see it, write-optimized DSO is no hindrance because essentially the data is coming into the cube as if there was no DSO in the middle. I do not see SAP suggesting a DSO anywhere between the source and business content cubes, especially in our case dealting with 2LIS_02_ITM, SCL, etc. to handle delta.
Are you saying that no delta management is possible without inserting a DSO before the cube? Please realize that WO DSO only brings data request by request without any summation and overwrite confusion.
What I puzzled at is the lack of comprehensive unfied and detail information either in documentation or a blog.
Please advise.
SM

Full and delta Data loads in SAP BI 7.0

Hi,
Kindly explain me the difference between full and delta data loads in cube and DSO.
When do we select change log or active table(with or without archive) with full/delta in DTP for DSO.
Please explain the differences in data load for above different combinations.
With thanks and regards,
Mukul

Please search the forums. This topic has already been discussed a lot of times.

Generic Delta with Timestamp Field

Dear SDN Team,
We changed one of our HR datasource from FULL to DELTA with Timestamp(TMSTMP)-Time Stamp(UTC).
Which Delta we need to take Timestamp(Local) or Timestamp(UTC)
Our Generic Datasource is based on Function Module.This data source contains HR Hours Data i.e Direct Hours & Indirect Hours.
With interval settings has
Safety Interval Upper Limit - 'Blank' .
Safety Interval Lower Limit - 1800
New status for Changed Records (Selected)
It is a HR Generic Data Source.
We are creating the records in PA30,PA40 and going to take the records from PA0000,PA0001
Delta type for this DS is "AIE" as our delta type process for our DS.
I am trying to load the INIT to Cube,but its not allowing to load,saying with 'AIE' delta type its not possible to load to cube.
I changed the delta type to 'ADD' then the safety interval limits changed to
Safety Interval Upper Limit - 1800 .
Safety Interval Lower Limit - Blank.
Additive Delta (selected)
Is it possible to load the Generic Delta Time stamp to Cube?
Please let us know what are the settings & delta type needs to be there to load the Generic Delta Timestamp to Cube.
Your suggestions are really appreciated.
Thanks and Kind Regards,
Lakshman Kumar G

Hi,
We used TMSTMP filed with Data element TZNTSTMPS with data type DEC Length 15 in Function Module & Extract Structure.
Default filed name is TIMESTAMP_UTC,Domain is TZNTSTMPS.
Generic Delta -
Filed name - TMSTMP
Timestamp (UTC) selected
With interval limits
Safety Interval Upper Limit 1800
Safety Interval Lower Limit
New Status or Changed Records selected.
Thanks and Kind Regards,

ABR complete delta with deletion flag via delta queue (cube compartible)

Hello
DS 2LIS_04_P_COMP is delta enabled with ABR complete delta with deletion flag via delta queue (cube compartible)
Is it possible to use this type of delta for ods? If yes , what kind of changes are required
Thanks

Hi
ABR means
A - After Image
B - Before Image
R - Reverse Image
Since updating DSO is usually in overwrite mode it requires After Image.
So u can use the data source with ABR delta to load into DSO (ODS).
Cheers.

Two Extractor logics for full and delta?

Hi,
I have a situation where in the logics for full upload and delta uploads are drastically dfifferent!
What is best way to deal it?
shuould i have two different extractors for full and delta ?
Raj

Hi Raj,
I hope that u are working with the Generic Extractors. If the volume of the posting is too high then u need to restrict the data definitely from R3 side interms of the performance. And u need to maintain the Delta Functionality for the same.
If u cannt maintain the Delta from the R3 side then atleast try to restrict the same from BW side at the infopack level where u can extract the data based on the changed on and created with the two different IP's and update the same to the ODS(here make sure all the objects are with the overwrite).... and then u can maintain the Delta load from ODS to the Cube easily..
If the volume of the data is pretty less then u can use Full load to the ODS and then Delta to the Cube.
Thanks
Hope this helps..

DELTA AND INIT TO CUBE Simple

Please help me with this, I have a bad red delta request coming from billing ods in bmw cube so i deleted the request, but bmw cube has other green request coming from order and delivery which is fine green and success.
now to resolve this i deleted the red delta request of billing and also deleted every thing from ods and i redo the set up table and did init to billing ods but now when init goes to bmw cube it fails please tell me the exact step to resolve this please tell me how can i set up the delta again so that init from billing ods goes to cube
help me with navigation step.i do not want to delete the entire data from cube to resolve this
thanks
soniya
soniya

Let me try to get it.
Your ODS has delta coming in for a specific fiscal period? Is there no overlap (meaning one billing document coming in as new into the ODS and cube is not changed in the next period)?
If not, there may be a problem.
Consider the case where you had a document which came in earlier (successful) request, and is there in the cube (say with a original qty of 25). Now, say your last delta had a change to it (of qty increased by 5, say), and this delta failed to go to the cube. Now you are doing a full load with repair for this period.
Since you are doing a full load, it will bring a qty of 30; however your cube has the earlier record (with a value 25), so instead of total 30 (correct) you will end up with a value of 55(incorrect).
The difference here is that your delta which failed had a qty of 5 (incremental amount) for this doc, but now you are bringing the qty of 30 with a full load.
This is a theortical scenario which can cause inconsistency to your data. If there is no case where an earlier existing record was being changed in the last delta (ie last delta had all new records) then you should be ok.

Before designing cube/ODS in BW how can weknow that the datasource is delta

HI All
Before designing cube/ODS in BW how can we know that the datasource in source R/3 is delta enable or not? I mean what type of datasource is this?
And aslo what do we mean by Standard Extractors? will this mean like for this there wont be any datasource or table? Iam nill in this part? can anyone explain me regarding this
Regards
Balji

Hi Balaji,
To find whether a datasource is delta enabled or not goto R/3 -> se11/se16 -> roosource table -> your datasource -> check the "DELTA" field value. If it is blank then no delta is supported.
All extractors would have a datasource and extract structure associated with it. It does not matter whether it is business content or custom.

Delta between DSO and Cube

Hi All,
I have been working on a scenario where in we have to realign org structure information of some sales orders , now we have existing sales orders data in DSO , which feeds to a cube . As part of the realignment some master data attributes, more specifically Customer Master attributes, will be changed in R3 for those Sales Orders.
These attributes are part of the transaction data load which is happening to the DSO from the source, now since this transaction load is taking time, to speed up the process of realignment in BW I have used a routine to lookup the masterdata attributes from 0CUSTOMER in BW.
so before BW pulls the realigned data ( Sales Orders ) from R3, I will run a self loop in the DSO where in it will do a lookup in the 0CUSTOMER master data in BW to get the updated customer attributes (ofcourse the 0CUSTOMER load will happen before we do any realignment of the source data) .
Once the self loop transformation is completed and the sales orders are updated with the updated customer attributes, I will load the data to the cubes. (delta load)
Now once the sales order realignment is finished in R3 , I will pull the same set of data in the DSO .
Now the question is, is it necessary that I do a reinit of the cube before I load the second set of data to the cube?
I guess it is not necessary.
Please share your thoughts.

Hello Partho
I understand your KF are overwrite in DSO. But in BI7 flow delta from DSO to cube is request based.
When you will do a self-loop, same records ( I guess you have already loaded them to cube) will have different request id.
As a result your Change Log table will get different id after activation. So same record will get loaded to cube and which will make all your KF in cube doubled.
I believe to make correction in historical records in cube either you have to delete cube content and then run delta from DSO to cube. As first time delta will read Active table of DSO you will get all KF correct in cube..
Else, you have to delete all those previously loaded record from cube selectively.

Difference: Full load, Delta Load & INIT load in BW

Hi Experts,
I am new to SAP BW Data warehousing.
What is the difference between Full load, Delta Load & INIT load in BW.
Regards
Praveen

Hi Pravin,
Hope the below helps you...
Full update:
A full update requests all the data that corresponds with the selection criteria you have determined in the scheduler.
You can indicate that a request with full update mode is a full repair request using the scheduler menu. This request can be posted to every data target, even if the data target already contains data from an initialization run or delta for this DataSource/source system combination, and has overlapping selection conditions.
If you use the full repair request to reload the data into the DataStore object after you have selectively deleted data from the DataStore object, note that this can lead to inconsistencies in the data target. If the selections for the repair request do not correspond with the selections you made when selectively deleting data from the DataStore object, posting this request can lead to duplicated data records in the data target.
Initialization of the delta process
Initializing the delta process is a precondition for requesting the delta.
More than one initialization selection is possible for different, non-overlapping selection conditions to initialize the delta process when scheduling InfoPackages for data from an SAP system. This gives you the option of loading the data
relevant for the delta process to the Business Information Warehouse in steps.
For example, you could load the data for cost center 1000 to BI in one step and the data for cost center 2000 in another.
The delta requested after several initializations contains the upper amount of all the successful init selections as the selection criterion. After this, the selection condition for the delta can no longer be changed. In the example, data for cost
centers 1000 and 2000 were loaded to BI during a delta.
Delta update
A delta update requests only the data that has appeared since the last delta. Before you can request a delta update you first have to initialize the delta process. A delta update is only possible for loading from SAP source systems. If a delta update fails (status red in the monitor), or the overall status of the delta request was set to red manually, the next data request is carried out in repeat mode. With a repeat request, the data that was loaded incorrectly or incompletely in the failed delta request is extracted along with the data that has accrued from this point on. A repeat can only be requested in the dialog screen. If the data from the failed delta request has already been updated to data targets, delete the data from the data targets in question. If you do not delete the data from the data targets, this could lead to duplicated data records after the repeat request.
Repeat delta update
If the loading process fails, the delta for the DataSource is requested again.
Early delta initialization : This is a advanced concept, but just for your information ...
With early delta initialization you can already write the data to the delta queue or to the delta tables in the application while the initialization is requested in the source system. This enables you to initialize the delta process, in other
words, the init request, without having to stop posting the data in the source system. You can only carry out early delta initialization if this is supported by the extractor for the DataSource that is called in the source system with this data
request. Extractors that support early delta initialization were first supplied with.

Extraction - full or delta or neither?

Hi all,
I have encountered a strange behaviour.
I am having a DataSource extracts data from R/3 to BW. In the "Test DataSource" screen, I put a range 2007.10 to the posting period, and it extracts all the records for 2007.10 for me.
But when I execute the InfoPackage in BW, and subsequently DTP and activation of DSO, I have got both 2007.10 and 2007.11 data in my DSO (which means all data ran into my DSO).
I suspect there is something wrong with my DS or DTP, because in my Data Transfer Process Monitor under "Details" tab, under "Process Request", there are multiple data package -- and it seems like this includes all the previous request and load that I have performed onto this DSO.
In my DTP extraction mode, I have tried both "Full" and "Delta" and in both cases, I got same problem.
Does anybody have any clue on how to resolve this? Is there a way to reset or I have missed out something? Appreciate for help. Thanks a lot.
- JK

Hi Alec,
If I delete the InfoPackage, would all the requests be deleted as well?
What I have tried is to delete the InfoPackage, delete data in DSO, and create Infopackage again, then execute DTP again.
As said, the PSA got only the data I need, but when loaded DTP and activate ODS, I got everything...
Still don't know why it behaves like that...

I have installed Angry Birds Seasons HD on my iPad. It has installed, but another icon with a full blue bar with 'installing' written below is displayed. It's not even being deleted... HELP!

I have installed Angry Birds Seasons HD on my iPad. It has installed, but another icon with a full blue bar with 'installing' written below is displayed. It's not even being deleted... HELP!

Repeating your question in the post doesn't fully explain what the problem is. Are you saying that you installed the game and it is trying to install again?
Without knowing anymore than why you have posted ..... try rebooting the iPad and see if the installing resumes, the download disappears .....
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Full-Init-Delta Loads

Friends
I have done full loads into a ODS and then I did Init with no data transfer. But the Message said that the request cannot be activated because the ODS has had full loads and activating INIT and DELTAS is not possible...Any Ideas?
Regards
VISHAL

Hi Ashwin,
there is a seperare procedure to activate delta mechanism in ODS. After you load the full requests you cannnot run init without making all the full requests to "Reapir full requests".
See SAP Note: 689964
Symptom
You want to switch the upload procedure for an ODS object from full to delta. However, the delta initialization fails with a message indicating that there are already full uploads in the ODS object and therefore inits or deltas cannot be posted or activated.
Other terms
Delta; ODS object: delta initialization, RSM 098, full, Init
Reason and Prerequisites
If a full upload occurs once for an ODS object, you can no longer activate an init for the same DataSource/source system combination in this ODS object. The system does not check for overlapping selection conditions.
Solution
In the case if an ODS object, you can change the upload procedure from full to delta by subsequently marking the full requests that exist in the ODS object for this DataSource/source system combination as repair full requests.
These requests are therefore characterized by the fact that they can be posted into any data targets in any sequence. The repair full requests are never checked in a data target, that is, you can activate initializations and deltas (also with selections) in the ODS object. All ODS objects filled with these full requests behave as if the full requests did not exist in the ODS object.
Checks do not take place in all of these ODS objects.
Note the following:
Since the repair full requests are not checked, duplicate data records may be created or data may disappear if there is a subsequent init.
Since the repair full requests are not checked, you should take account of the extractor behavior, update modes, aggregational behavior of key figures and characteristics, among other things, when you are deciding whether you want to mark the full requests as repair full requests.
If you perform an init simulation after changing to repair full requests, make sure that no data is updated between the last full upload and the first delta upload.
Procedure for changing full requests to repair full requests:
After you import Support Package 19 (3.0B) or Support Package 13 (3.1C), the <b>RSSM_SET_REPAIR_FULL_FLAG report is available which you can use to convert all full requests for a DataSource/source system combination that are in an ODS object into repair full requests.
Before you import this Support Package:
Use transaction SE16 to call the RSSELDONE table.
Here, enter an "x" in the "Repair_Full" field for all full request records that you want to mark as repair full requests.</b>CAUTION: This ONLY concerns those requests that begin with 'REQU_...'. The repair flag CANNOT be set for activation requests that begin with 'ODSR_'.
If the full requests still exist in the PSA, you can also use the scheduler under the 'Scheduler' menu option in the PSA tree (when you post from the PSA) to switch a PSA full request to a repair full request before loading.
If you load new requests with an InfoPackage, you can also assign the repair indicator to this full report.

Delta with DTP Running Longtime--Urgent

Hi Experts,
I am doing a delta(Init) with a DTP from ODS to Cube in between we are having transformations in which omaterial hierarchey is included and the delta is reading data from the omaterial hierarchey table awhich we are seeing in sm50 nd its taking longtime how can we make the load faster.

hi,
hierarchy table looking will take long time as it will look up additional keys while retriving the hierarchy data.chk out have some other option to get master data look up.

Full To Delta (changing load type)

Hello Everybody
I am planning to convert few laad type from FUll to delta because its just taking too long to load. But here are my questions.
Besides the fact that (full load)it's a business requrement(snapshot); i cannot change it right or there is still a way.
1. what are the technical considerations for converting full load from a dso to a cube . If ths dso is getting a full load itself does it have to be set to overwrite to further do a delta to a cube. what if the dso is getting delta load . do i have to consider from source to dso as well if its delta or full; how does it affect it.
2. what happens to the existing laods/requests in a cube/dso if i change the load type. (does it get affected)
thanks

Hi,
1. When changing the data load to delta from DSO to cube, just you can go ahead an do init. Since the base leve is DSO it doesnot matter if the base level data load is full or delta. Also make sure the DSO is standard one. If the source is DSO there is no problem in converting from full to delta.
2. Make sure only one full load exist in cube. Then do a init and going further you can pull delta. The existing data in DSO will not be affected or cube data. Since delta will fetch data from change log table there will not an issue.
Regards
Akhan
