Loading delta to master datasources

Hi All,
I am a begineer in SAP Bi,can anyone tell how to load delta for master data sources.i am in an implementation project and while loading master data found that some datasources have full updatet and some have init update,so my doubt is how can we load delta data to full update datasources..And i know about attribute change run,do we execute attribute change run after getting the delta load ??/
Thanks,
BI_STAR

Hello Star,
If you want to change the update of Master data datasources from FULL to DELTA, for that you need to check whether datasouce is compitable for DELTA, then only you can perform delta Loads to the corresponding master data datasources.
For Checking the Delta Compitabilty, please check this in T-Code RSA6, Once you open the Datasouce.
If you are changing it from FUll to DELTA, then please Init with out data and then it gives delta option in the Infopackage.
It really does not matterfor FULL or Delta, we should perform attribute change Run , this for Aggregates adjustment for newly created Master data.
Thanks

BW - Delta for Master data not loading

Hello All,
I am not able to load delta for master data of vendor and material.
The initial load works fine but when I load delta it gives an error
" The extraction program does not support object 0vendor"
" ALE change pointers are not set up correctly"
Do i need to activate the change pointer in BD61. I was not sure so checking up with all experts.
Regards
Vanya

Hi Ravi,
We faced the same problem as you for 0MATERIAL_ATTR and we solved it by the following steps,
1. Delete the previous Delta Init for the InfoObject
If you have access to R/3 Side you can follow the steps or you can follow the BW Steps
Goto RSA7 ->Select and Delete the Init for the InfoObject
From BW Side
InfoPackage-> Inti for Source System -> Select & Delete
2. Execute the Init InfoPackage for the InfoPackage again.
3. After successful completion, execute the delta InfoPackage.
We have have got resolved by doing these steps and it may help for your problem as well.

Master datasource delta problem.

Hello,
We are in process of implementing logistics module for our client. We are in BI7 and using all BI7 data flow for master and transaction data .
While working with all master datasource which is supporting delta functionality, we have faced following issue. All this datasources are based on ALE pointer. somehow we are getting the same number of records in delta load...basically it is bringing the same records in delta load everytime.
E.g - 0CUSTOMER_ATTR . when i extracted the data first time in delta load, it has brough 1200 records and from that day it is bringing 1000+ records in delta load. even if i start the delta in one min, it is bringing that much data. I am very confident that, there is not much changing in ECC ..but here it is bringing it from change pointer table and not updating the same table once the extraction is completed.
When we dig into this issue, we realize that, somehow change pointer is not getting updated in change pointer table . We haven't changed anything in standard extractor but still it is happening with all master datasource (delta based ) extractor .
Can you please help me solving this issue ?

Delta problem for enhanced field in master datasource

Dear Experts,
I have a master datasource 0customer_attr. I have enhanced it with field sales group. Daily delta comes for this datasource.
But when user changed sales group for a customer from s1 to s2 then it is not coming in delta.
Still there is old sales group exist in BI for particular customer. In short , delta is not coming for enhanced field.
Please advise what should i do ?
Regards
Shweta

The problem is that no delta is posted to the message type for KNA1 in the bdpcv/s tables because the orignatting field is a KNVV field
So if KNVV was changed ie sales group it will not post a ale change pointer for KNA1 therefore the delta for KNA1 will not pick up any change
However if there was a change to KNA1 on the same day as the KNVV changwe then the delta will pick up the change
The way to get around this is to either use a KNVV delta datasource into BW and then enhance 0Customer that way via transformations into the customer infoobject in BW only
Or to put a user exit into the KNVV change on R3 to generate an ale change pointer for KNA1(ie every change in KNVV will generate a change in the KNA1 extractor)

How to load delta to 2 target ODS 's from a single ODS using process chains

Hi BW Gurus
I am having a current ODS based on 2LIS_02_SCL, deltas also are working fine for it.
our requirement was based to have 2 target ODS on this existing ODS by using export generate datasource.
I have to build a process chain that should enable us to load delta in our target ODS.
Earlier manually for DEV purposes ,i was using the Update data into data targets from the source ODS, this was enabling us to load deltas. But to automate this process we will require a process chain.
Finally , is there any process type in process chain for " Export generate Datasource".
please suggest a good methodology for this scenario.
Thanks in advance.

Hi Ashfaq,
Loading from ODS to CUBE is same as loading from datasource to ODS only.
1. Create export datasource.
2. Create update rules from ODS(export datasouce) to CUBE.
3. Create infopackages(if you dont want to use generated once).
4. include infopackage in process chain to load fromODS to CUBE.
Intialize first manually and change settings in process chain infopackage to "Delta".
5. You can append/enhance existing process chain(loading from datasource to ODS).
Hope it Helps

Generic delta for master data

Hi All,
I am trying to create a generic delta for master data "equipment" . table in SASP is "EQUI". I am choosing ALE delta . in that I have to provide table name and "changed doc object' . when I give "equi" as table name and "aedat" (changed on ) as "changed doc object' -
it is throwing error.
also when I tried for time satmp /calday delta , the delta doesnot work when changeed are done. don't know why?
Any idea what has to be given in these fields.
Regards,
Dola
Edited by: Dola das on Mar 17, 2010 12:55 PM

Hello,
TCDOB is a table where you need to maintain entries for Generic Detla.
Please goto SE16 : enter table name TCDOB
In the selection Screen Enter Object as EQUI and check the Number Of Entries..
I guess you need to maintain the number of fields on which the change is dependent for Detla ()
I treid creating the same Datasource Using Ale Detla
It worked and saved without errors :
i have the following entries in TCDOB table
OBJECT          TABNAME
EQUI            EQKT
EQUI            EQUI
EQUI            EQUZ
EQUI            FLEET
EQUI            ILOA
Please tell me your count and entries..
so that we can discuss this Further
Also if you find if there are no entries then you can Go to SCDO tcode and maintain entries with respect to change object.
waiting for your feedback

What r the ways to reduce the load time of master data

Hi
The full load of the master data load IP is taking 18hr to 2 days loading on average 2516360 Records
Is their any option to reduce load time as its causing data base lock and impacting transports(other than data selection)
Thanks in advance
Anuj

You will have to do some research. What MD extractor are you talking about?
Test on R/3 system: First try to extract a considerable amount of records via transaction RSA3 in R/3 (10.000 or 100.000). Keep the time that it takes.
Extract the same into BW but only into PSA. Again measure the time.
Load data from PSA into datatarget and see how long this takes. You should now have a picture on where the performance problems are located.
Is the performance also bad for small loads or is there a boundary before which performance is ok. (in other words, is loading 200.000 records ten times longer then loading 20.000 records?)
Suspect the following in R/3:
- datasource enhancements in R/3. A redesign may improve your extraction in a big way.
- missing indexes. If you are extracting data from tables without proper indexes the extraction performance can be dramatic.
Suspect the following if loading to PSA is bad:
- Datapackage reads data in small chunks (much smaller than 50000 records). Overhead causes more time than the actual data transport.
- Network problems. Maybe the network is congested by other servers?
If loading from PSA to datatarget is slow:
- Check start routines for performance.
- Are enough batch partitions available? Sometimes activation of ODS can be improved by more parallel processes.
- Are you using a lot masterdata-lookups when filling the datatargets?
When you report you findings in this forum we may be able to help you further.

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.

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.

Load Failure for Master Data object

Dear Sdns,
                    Am doing daily master data loading for VENODR_ATTR master data object.... Am loading it through DELTA Update.... I got an error in Status Tab.
rror message from the source system
Diagnosis
An error occurred in the source system.
System response
Caller 09 contains an error message.
Further analysis:
The error occurred in Service API .
Refer to the error message.
Procedure
How you remove the error depends on the error message.
Note
If the source system is a Client Workstation, then it is possible that the file that you wanted to load was being edited at the time of the data request. Make sure that the file is in the specified directory, that it is not being processed at the moment, and restart the request.
The Error Message is : - Update mode R is not supported by the extraction API.The application program for the extraction of the data was called using
update mode R . However, this is not supported by the InfoSource.
Kindly Help me if any of the Snd people might have face this kind of problem...
Answering Getz Appreciated,
Warm Regards,
Aluri

Hi Aluri,
The file might be used or being edited by some other person when you are doing the delta.
CHeck the source system connection @ AWB.activate it.
Follow these steps
1. Activate transfer rules for data source in source system.
2. Activate the ODS
3. Activate the update rules (ods to ods and also ods to cube)
5. Right-click at the ODS, choose 'Generate Export Data Source'
6. Replicate the data source
7.se38---->RS_TRANSTRU_ACTIVATE_ALL for source system .
Then start data loading again.
Hope this helps.
Assign points if useful.

Master Datasource Update for custom fields

I have a standard master data source for 0customer, I need some custom fields that are enhanced in the same SoURCE TABLE KNA1. please let me know if
1. i can create the generic data source Z_DS_CUSTOMER for custom fields only from KNA1
2. Create transformation 1 to Map the data source Z_DS_CUSTOMER to Ocustomer to load the custom fields only and set no transformation for other standard fields
3. Create transformation 2 to Map the data source 0customer_attr to same Ocustomer to load the standard fields.set no transformation for other custom fields
4. Then Load via DTP Standard fields first via transformation 2
5. Then Load via DTP custom fields first via transformation 1
Will the above will work fine, and I can avoid any enhancement to master datasource 0customer_attr
please help me with solution.

Hi all my dear friends,
I have seen the recommendation by my SAP collegue and Anil
1. infoobject as Target and
2. in between Standard DSO
1 transformations as you mentioned from 1 IS
3. Common Info source
2 transformations as you mentioned from 2DS
4. Datasources (2no's ) as source to splly to data to DSO
Please tell me what is the need to do all the above why can't I feed directly the Infoobject with the below PLEASE tell me what will be the bad impact on design if I do the below.since my client is asking justification for build of each BI object
1. infoobject as Target and
1 transformations as mentioned from 1 IS
2. Common Info source
2 transformations as mentioned from 2DS
3. Datasources (2no's ) as source to splly to data to DSO
I am not going for enhancement since it is not populating the datasource in rsa3. if you can correct that it would be great.
I have the same code for all custom fields none of them is working no records are pulled in RSA3 For custom field ZZSTAT.
Please help me with this
Thanks

Data source enhancement while loading deltas

Hi Experts,
I've a scenario that while loading deltas do we perform data source enhancement if we can how do we do that.
This is i got a requirement, to enhance 2LIS_11_VAITM, while loading deltas. Now how do I go about this what are the exact steps that i follow to enhance.
Could s'one help in this regard because i'm new to the ABAP.
Thanks & Regards,
Amar

hi,
Go to the extract structure of this datasource and display the extract structure of the datasource in SE11 and click on APPEND STRUCTURE and click on the tick mark and try to add the fields required into the lines. You need to populate the data on to these new enhanced fields in the user-exit. But when you move these transports to production environment, you have to stop deltas and re-initialize the datasource....
Hope it helps...

How to catch the delta of generic datasource created on table EBAN?

Hi Guru,
I am facing a problem about the delta of generic datasource i created on table EBAN.
when I convert a PR into PO, this PR was created several month ago, this PR will not be caught into delta package.
how to get this PR again after it was converted into a PO?
many thanks.

hi,
If you have any fields(calday,timestamp,nemric pointer) in your table , using this fields any one we can enable delta.otherwise one option is there but your table is small valoum of datas.
first data load(full) r3 to bw side cube,then using open hub service download data from cube to any file (excel ,csv) then r3 side create one table using that flat file, then load download file to r3 new table using (LSMW - tcode r3 side).
now compare your genric extroction table and new table using ABAP coding , then you have any new record or changed find update new table first then BW side .
using this type we can enable delta for genric extrocation.

sundar.
