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.

- 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

Delta and full uploads in the same data target?????

I have found that delta load and full update from different infopackages are getting loaded into the same data target that is ODS object. when do we go for such situation, can any one explain me in detail or give me some documents to know more about it.

Hi,
You have not clearly mentioned that those infopackages are ctrated on the same Datasource or not.
This way of uploading is very common when we need to upload some data from R/3 and some other data from Flat file into the Info cube. And GenerallyFlat file data would not be given in Before image and after image way, thats why we need to do full uplaod. The deleetion of already uploaded flat file data fromt he cube (before new upload from flat file ) depends up on whether the data to be uploaded from flat file system is always new data or not. And generally R/3 Extractor is capable of giving deltas, thats why only delta loads to the cube.

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

Need a single point of view on date selections for Delta and Full load IP's

Hi Experts,
Every year we are facing issues on date selections for data extraction, for example the Delta or Full selections for particular IP is like 2005 to 2008 , in this situation, for the year 2009, this IP is picking 0 records as the selections are upto 2008 only.
My requirement is, I need to check the selections of all the IP's in the system and want to change on need base if the selections are getting expired instead of going and checking manually to each and every IP as the system is having around 3000 IP's, which is a tedious job.
Guys, please let us know if there exits a Table/Program or any other way to check it.
Inputs appreciated.

Delta and Init Upload

Hello Friends
I have some confusion regarding the difference b/w delta upload and Init load.
Are they related to each other, if yes then how? Cant get a clear explanation for this.
Secondly, If i have loaded data into a cube from an ODS with request no for eg. R1 and other req no with R2. If after the successful request and data going into the cube..after some time i change the req. R1 status from green to red, will i be able to view the data in the cube coming from req R1?
Need ur comments
Regards
Rohit

Hi Rohit
Have quick look at the follwoing thread it was already discussed
Re: init delta
Re: Delta and INIT loads
Coming to your issue yes you are able to see the data bcz once the data is
suceesfully loaded in to the cube .it will maintain the data .It wont bother about
ods request..

Delta and Full load from a single Delta ODS

I have delivered 0DS 0GT_DS01 that is being loaded from R/3 as a delta update. This ODS is then loaded to a delivered InfoCube 0GT_C01 as a delta.
My question is this, can I create update rules and a Infopackage to do a full load from 0GT_DS01 ODS to my custom ODS ZGT_DS01?
I kind of remember from my BW310 class that in release 3.5, if I have an ODS to InfoCube Delta update all other updates from that ODS must be a delta also.
Regards,
Mike...

Siva,
I created my update rule without a problem.
I created the Infopackage with my ZGT_DS01 ODS at the target, the update mode as FULL and I saved the InfoPackage. After SAVE I went to the drop-down menu, Scheduler ==> Initialization For This Datasource and there is a Delta present.
The Infopackage works OK when I run is from RSA1, but when I put the Infopackage in Process ChainI get and error "Delta upload is only possible after successful initialization". What I see in the Manage screen for my ZGT_DS01 ODS is a request for a full load followed by a request for a Delta.
Any Ideas why the infopackage works in RSA1 but not in a process chain?
Regards,
Mike...

Inits, deltas and full

Hi Experts
I am trying to clarify the data flow in 2004s.
1. If I am loading from R/3 datasource (Which is delta enabled) to a DSO in BW, i first load a full load with initialization with data transfer using an infopackage. I do the delta load with another infopackage selecting delta.
2. The above step only brings data to the PSA. From the PSA, DO I NEED TWO DTPS? one for full and other for delta?
3. From the DSO to the cube, do I need two DTPs again? Or a single DTP with extraction from the change log as delta is enough, even for the first load from the DSO to the cube?
Can someone confirm / clarify this?
Jason

1. If I am loading from R/3 datasource (Which is delta enabled) to a DSO in BW, i first load a full load with initialization with data transfer using an infopackage. I do the delta load with another infopackage selecting delta.
Thats correct.
2. The above step only brings data to the PSA. From the PSA, DO I NEED TWO DTPS? one for full and other for delta?
you need not do two DTP's to collect the data from PSA, design one DTP in delta mode from PSA, it would all the request in the PSA, no matter if its full or delta in the first run, from the second run it would pick all the requests that are new after the first run.
3. From the DSO to the cube, do I need two DTPs again? Or a single DTP with extraction from the change log as delta is enough, even for the first load from the DSO to the cube?
just as said in point 2, one DTP with change log as delta would do the job

Delta and Full process chain for same master data target.

Hi Friends,
Can I do full update and delta update through process chain for same master data target and from same source ?
Regards
shekar reddy

Hi Sriram,
why you want to load full and delta for same master data object?
you can achieve this but make sure that you select repair full option for full load IP.
you have this option in scheduler in menu bar

Delta and Full load in RSA3

Hi I have managed to extract data for 2LIS_13_VDITM if the load is full. However, when I try the Delta it gives 0 records. Do I just need to modify some documents or do I need to create a queue in RSA7, where there is no entry for the 2LIS_13_VDITM. If I need to create a queue entry in RSA7 could you outline the steps. Thanks

Hi venkat,
There seems to be some confusion. What i suggest is to go for a re-init. The following steps might help you doing that.
1. In the source system, goto LBWE and for the application component 13, run a V3 update immediately.
2. In the BW system, pull the delta( even if it 0 records fine )
3. Delete the content of the data target and delete the init fkag for the data source.
4. Go back to source system. Delete the content of the setup table and run the setup table again.
5. In BW, initialise the datasource.
6. Go back to source system and schedule the V3 update job.
7. Now you can pull the deltas with delta IP.
If in any step ur having problem, pls post it.

Delta AND Full load on 2LIS_11 Extractor

Dear All,
I have a 2LIS_11** extractor in place which loads data via delta. Now I want to add a full load through the same extractor to a new infoprovider.
What is the scenario to do this? I know that I need to fill the setup tables, but won't that conflict with my delta load?
Your response will be appreciated and rewarded.

Hi,
as long as you don't load the data into your already existing ODS you will be fine.

Delta and Full Load question for cube and ODS

Hi all,
I need to push full load from Delta ODS.
I have process chain.... in which the steps are like below,
1. R/3 extractor for ODS1 (delta)
2. ODS1 to ODS2 (delta)
3. ODS2 to Cube ---> needs to be full load
Now when i run process chain by further processing automatically ODS2 does init/delta for Cube.
How can i make it possible for full load ??
can any one guide anything in this ?
Thanks,
KS

Hi,
1. R/3 extractor for ODS1 (delta) : This is OK, normally you can put the Delta InfoPack in Process Chian
2. ODS1 to ODS2 (delta): It automatically flow from ODS1 to ODS2 (you need to select Update Data automaticall in the Targets at the time of ODS creation)
3. ODS2 to Cube ---> needs to be full load :
This you create a Update rules from ODS1 to Cube then Create InfoPackage in between ODS2 and Cube then do full loads. You can delete the data in the CUbe before the load ann dthen do Full load to Cube.
Note: In ODS2 don't select Upadate Data autmaticlly to Data Targets
Thanks

Delta and Full load Process Chain

Hi Guru`s,
I have a one standard target (infocube) which is fetching data from the 3 datasources. Out of 3 datasources 2 are standard datasources and 1 is Generic datasource (Custom datasource).
These 2 standard datasources have Delta load and Generic datasource have full load.
I have to design the process chain by using Full load and Delta load.
Can any body tell me how could I achieve this requirement.
Thanks in Advance,
Venkat

Hi,
Please check the follwing steps,
Delta chain:
Step- 1 Start varitant
Step- 2 Delete PSA request(Full- ur Genric DS)
Step- 3 delta infopackage1
Step- 4 delta infopackage2
Step- 5 full infopackage(Genric DS)
Step- 6 DTP1
Step- 7 DTP2
Step- 8 DTP3
Full chain:
Step- 1 Start varitant
Step- 2 Delete PSA request for PSA1
Step- 3 Delete PSA request for PSA2
Step- 4Delete PSA request for PSA3
Step- 5 FUll IP1
Step- 6 Full IP2
Step- 7 Full IP3
Step- 8 DTP1
Step- 9 DTP2
Step- 10 DTP3
I have given steps upto DSO only.
Thanks,Girish

DTP Delta and Full Load...

Dear All,
I'm working with SAP BW 7.3 and I have a standard data flow, starting with DataSource, DSO and InfoCube. My process chain faced an error and for last week or so I could not fetch deltas. To remove the error I had deleted all records from InfoCube, since I had all requests available into DSO. Then I manually loaded Full Load from DSO to InfuCube. But next day when my process chain executed it brought all precious and new records again into InfoCube, as the delta was properly fetched into DSO but it did not come into InfoCube, as it was coming before. When I checked Active and Change Log tables of DSO these two had same number of records.
1. What could be the reason that delta DTP between DSO and InfoCube is not fetching only delta records, it was fetching deltas records before full load?
2. Have I made a mistake or missed any setting in DTP while executing full Load DTP between DSO and InfoCube?
3. What are these options for in Extraction Tab of DTP and when we use following options and why:
    i.   Active Table (with Archive)
    ii. Acitve Table (Without)
    iii. Archive (Full Extraction only)
    iv. Change Log
I will appreciate your reply.
Many thanks!
Tariq Ashraf

Hi Tariq,
Please check the below:
Delta Init. Extraction from
Active Table (with Archive)
The data is read from the DSO active table and from the archived data.
Active Table (Without Archive)
The data is only read from the active table of a DSO. If there is data in the archive or in near-line storage at the time of extraction, this data is not extracted.
Archive (Full Extraction Only)
The data is only read from the archive data store. Data is not extracted from the active table.
Change Log
the data is read from the change log and not the active table of the DSO.
Hope this answers your question. Let me know if any required.

BW Delta and Full load

Hi !
This is a simple question with BW 3.5 :
A standard extractor with Delta is extracting everyday delta to 1st level ODS -> 2nd level ODS -> Cube.
Now i want to add 2 ODSes in same flow and they should also catch all these delta. Along with that I want to load for remaining period of this month (ex. Full load from 1st to today of the month and then onwards delta)
So new structure would be
0CRM_SALES_ACT_1 -> Level 1 existing ODS delta -> Level 2 existing ODS Delta
-> New level 1 ODS with delta -> New Level 2 ODS with delta
Can you please let me know how to do that ?
Full , delta info package ?
(FYI - i loaded full load for history and then tried delta, but delta failed saying Full load is already there in system)
Please do not post duplicate threads
Edited by: Pravender on Apr 12, 2011 7:08 PM

Partik,
My suggestion is load data from exiting Level 1 DSO to 2 New DSO's instead of loading directly from source to New DSO's.
To do that... removed initialization from Level1 DSO to 2nd level DSO and Re-Initialize WITHOUT data transfer by considering new DSO's also and continue delta's.
Use full load infopackages to load historic data from Level 1 DSO to 2 new DSO's.
Flow now should be:
0CRM_SALES_ACT_1 -> Level 1 existing ODS delta -> Level 2 existing ODS Delta
Level 1 existing ODS delta -> New DSO's
If FULL loads already there in DSO's further delta's wont work. Convert FULL loads to repair full load using Program: RSSM_SET_REPAIR_FULL_FLAG.
Then continue delta's.
Hope it Helps
