How to get delta - datasource

Hi There!
Excuse me for some lame q's- being a starter in BW I'm looking forward some help to fix an issue.
There is a table in R3 for I need to see if a particular data was recorded but unf this table is refreshed every fortnight. But the scenario extends to BW data extractor and source for which config is active. How can we see the data replicated in BW for a specific date? Will there be any history maintained? Pls can someone throw some light on it?

Hi,
Am unable to understand your issue description.
Assuming as you need to see the last refreshed data from ecc.
Actually we never replicate data into bw. We load ecc data into bw by using extractors/info pack.
if your data source supports delta , then you can check your info pack monitor screen.
based on that you can see last night data was refreshed or not.
Even your data source have any date field then at PSA you can check data by filtering on date field.
Even go to your data source-->manage-->see the latest loaded request.
Thanks

How to get Delta ILSR : suppliers wont import

Hello, im having problems getting the k7n2 delta ilsr, the suppliers wont import it to my counrty (malaysia), any suggestions on how to get it?

Have you tried buying it online? You'll pay an arm and a leg for shipping probly which wouldn't make it worth it...
Have you tried paying anyone off like say a distributor there in your country? Give him 100 bucks *equivelent* and see what he says heheheh
Have you called around to see who may have 1 in stock there already?
Have you looked on the MSI website to see where their local CS house is or the closest one? Maybe they'll sell one directly to your local retailer...
Get creative...where there's a will there's a way!

How to change Delta Datasource to Full Load?

Hi All,
I have an issue in my report which has Inbound Datasource (customized) from EKES and GRn from VBFA customized datasource.
Currently,
EKES is FULL UPDATE*
VBFA is DELTA UPDATE
My Scenario steps:
Step1:Inbound Created --EKES
Step2:GRn done--VBFA
Step3:Grn Reversed--VBFA
Step4:Inbound Deleted.--- EKES
So When the user deleted the INBOUND after REVERSAL, my EKES is full update, so it doesn't capture the deleted INBOUND based on our Datasource design to FILTER the AVAILABLE INBOUND. by type selection.
so before deletion GRN done in STEP 2, which is alreadt pushed to BI and after deletion of Inboubd GRN from VBFA is DELTA UPDATE, it doesn't capture the Deletion data...
In order to remove the deleted INBOUND from VBFA Infoprovider, I am planning easiest way to do FULL UPDATE...
May what are the precaution and steps to convert the DELTA update to Full UPDATE?
My flow 2PSA(EKES & VBFA)>2DSO(frm EKES & VBFA)->CUBE--->MultiProvider
Pls provide a good suggestion.

Hi ,
I mean to say, losing data in the sense..Once I do Full LOAD, will there any chance I miss data.
Also correct my below steps, if I am wrong,
1.Delete data from Target and PSA.
3. Run setup table-----HERE MY CONFUSION comes....my datasource is 0FI_GL_14. IT IS A FI datasources and this is not LO Method to do SET UP TABLE... or no need this step
2. Create Info Pak with FULL UPDATE.and run the Info pak
3. then run the DElte infopak, how the delta is set up..?
May I know what are the steps for FULL Update for FI?.
Thanks!

Collapsed request in infocube-How to get delta back

Hi All
I am loading the data from one ODS to cube1,cube2 and ODS1.
this is the delta update.
there is a load failure today.the load failure is due to the SID values missing for for one characteristic.
the requests in cube1,cube2 and in ODS1 are red.
but i the morning somebody made the red request in cube one in manage tab green and collapsed the same.
Actually i wanted to repeat the delta by deleting the requests in 2 cubes and ods.
But now the request in cube 1 is already collapsed what can i do now to get the last delta.
can anybody pls suggest.
urgent plsss....
Thanks in advance
S VR

Yes you are correct SVR,
We can not delete request once it is compressed. Selective deletion is not usefull in this case.
You can try following -- Be careful -- follow steps -- first try in Dev
If you know last requests generated todays delta in base/source ODS and those requests are available in PSA for reconstruction.... then...
1. Delete initialization from this source ODS to all 3 targets.
2. If requests are available for reconstruction, delete required requests from ODS.
3. Now initialize without data transfer from ODS to 3 targets(2cubes + 1ods).
4. Reconstruct deleted requests in Source ODS(it generated delta)
5. Pust delta to 3 targets.
Hope it helps

How to get title of an iview? Have only pcd-url...

Hi,
in my WebDynpro i need to get a list from PCD
that has
- the iview-ID
- the title of the iview
that resides in a directory.
I get the ids, eg. pcd:portal_content/rwe/bir/navigation/rwe.bir.ws.BIReports/rwe.bir.ivu.filter.tra.Istkosten_je_Periode_8
with the following source:
Hashtable env3 = new Hashtable();
env3.put(IPcdContext.SECURITY_PRINCIPAL, sapUser);
env3.put(Context.INITIAL_CONTEXT_FACTORY,IPcdContext.PCD_INITIAL_CONTEXT_FACTORY);
env3.put (com.sap.portal.directory.Constants.REQUESTED_ASPECT,PcmConstants.ASPECT_SEMANTICS);
InitialContext ctx1 = null;
DirContext dirCtx1;
List pageList = null;
try {
   ctx1 = new InitialContext(env3);
   //        Pass the iView location here...as Daniel said..
dirCtx1 =(DirContext) ctx1.lookup("pcd:portal_content/rwe/bir/content/generated/");
PcdSearchControls pcdSearchControls = new PcdSearchControls();
pcdSearchControls.setReturningObjFlag(false);
pcdSearchControls.setSearchScope(PcdSearchControls.SUBTREE_WITH_UNIT_ROOTS_SCOPE);
dirCtx1.addToEnvironment(Constants.APPLY_ASPECT_TO_CONTEXTS,Constants.APPLY_ASPECT_TO_CONTEXTS);
NamingEnumeration ne = dirCtx1.search("","(com.sap.portal.pcd.gl.ObjectClass=com.sapportals.portal.iview)",
     pcdSearchControls);
pageList = new ArrayList();
int i = 0;
while (ne.hasMoreElements()) {
i++;
IPcdSearchResult searchResult =
     (IPcdSearchResult) ne.nextElement();
//        This location will give you the full path of the page with page name
String location = searchResult.getName();
messageManager.reportSuccess("Got PCD-Url: " + location);
But - how can i get the title of the iview?
I tested also the code:
env.put(IPcdContext.SECURITY_PRINCIPAL,sapUser);
env.put(Context.INITIAL_CONTEXT_FACTORY,IPcdContext.PCD_INITIAL_CONTEXT_FACTORY);
env.put(com.sap.portal.directory.Constants.REQUESTED_ASPECT,   pcmConstants.ASPECT_ADMINISTRATION);
InitialContext ctx = null;
String objectID = "pcd:portal_content/rwe/bir/content/generated/";
iCtx = new InitialContext(env);
Object pcdObject =iCtx.lookup(objectID);
NamingEnumeration children = null;
if (pcdObject instanceof IAdminBase)
children = ((IPcdContext) ((IAdminBase) pcdObject).getImplementation (IAdminBase.CONTEXT)).listBindings("");
msgMgr.reportSuccess("Element: IAdminBase");
}else{
children = ((IPcdContext) pcdObject).listBindings("");
msgMgr.reportSuccess("Element: PCDObject");
Binding child;
int ch = 0;
while (children.hasMoreElements())
   child = (Binding) children.next();
   child.getName();
if (child.getName().startsWith("rwe.bir.ivu.filter")
     && child
     .getClassName()
     .equalsIgnoreCase("com.sapportals.portal.ivs.iviews.IPortalIview")) {
     msgMgr.reportSuccess("Element: " + child.getName());
then i get the title attribute, so getting something like
'locale= , Text="The title of the iview" '
But: how to collect both (title and id) in one way??
Thanks
Bernhard

HI Sarma,
Unfortunatelly, the variable p_infopackage is not accessible in the FORM.
It seems that the only variable I have access to is p_subrc...
To help you here are the first line of my selection routine :
program conversion_routine.
Type pools used by conversion program
type-pools: rsarc, rsarr, rssm.
tables: rssdlrange.
Global code used by conversion rules
$$ begin of global - insert your declaration only below this line -
TABLES: ...
DATA:   ...
$$ end of global - insert your declaration only before this line   -
    InfoObject      = 0TCTREQUID
    Fieldname       = REQUEST
    data type       = CHAR
    length          = 000030
    convexit        =
form compute_REQUEST
tables l_t_range structure rssdlrange
changing p_subrc like sy-subrc.
      Insert source code to current selection field
$$ begin of routine - insert your code only below this line        -
data: l_idx like sy-tabix.
          read table l_t_range with key
               fieldname = 'REQUEST'.
          l_idx = sy-tabix.
I think that your idea is the good one, but I do not see the how to get the datasource name for my infopackage...
If someone has another idea, it could be very helpful for me.
Thanks

How to get BI content on source system

Hi BI Expert,
We have applied NetWeaver 7.0 BI Content Add-on 3 SP09 to get DataSource Transactional Data: 0DF_IS_DFS_66 and DataSource Transactional Data: 0DF_IS_DFS_65. It went well but I can not see the datasources that we require both on BI and source system.
Could you please help us how to get these datasources on BI and finally transfer it to source system? After this, I need to activate and install it to get some reports that business requires.
Thanks for your kind help.

hi,
First of all these data sources are not available in your support pack 9 source system. May be you need to upgrade the suppor packages and see if they available in RSA5 (source system)
0DF_IS_DFS_65--for this check out following link.

How to resolve this issue.
And how to get the records of the partilcular day when the delta got failed.

Anyone have come across with this strange issue then help me out and i will rewarrd the points.
Urs,
Raki.

Hi
Can you provide more details about your extractor and data targets.
Are you loading delta to an ODS ??
If you are loading to an ODS, The only solution i can see is to get the missing delta records via FULL UPDATE. Because if you delete the error request from ODS it will also delete the 20 successful requests above it.

How can I get delta records for Generic Delta

Hi BW Gurus,
I am using Generic Extractor using View from CATSDB and CATSCO talbes. At the time of modifying and changing records I am unable to get those records in BW despite enabling delta in RSO2 screen. I am able to view those modified and added records in R/3 in tables. Plz help me how I get those records to BW.

hi,
After we loaded all the historical data uing full upadate . Implemenattion process is over , But we will have the Transaction data that will raise daily , So we have to store that New / changed data in Delta q , And extract them each day by Delta Update
So we will create an Info packege with the update mode as Delta , And schedule them when to start extraction , So we create the process chain uisng RSPC by giving the Info packege name . And extract the Detla daily as per schedule .

Hi Hari,
Sorry for late reply.
Once you have done the proper mapping by using the transaction BWA1
you need to write the BADI code which can be accesible from the following path:
Go to transaction SPRO
SAP Implementation guide ->Integration with other mySAP components ->Data transfer to the Business Information Warehouse->
Settings for the application specific datasources (CRM) ->
Settings for BW adapter->Execute Badi :BW adapter :Enhancement of datasources in messaging flow.
Select you the datasource enhancement implementation it will open the BADI Implementation..
go To interface tab and double click on the method..it takes you to the ABAP screen where you need to write the logic to populate the custom fields..
Please feel free to mail back if you have any quries.
All the Best..
Thanks

"Only Get Delta Once" - How to use this correctly?

Hi folks,
we are currently facing the following situation:
We have a data source only being able to deliver full update.
That's why we proceed as follows:
1.) Full-Load with Infopackage to PSA
2.) Delta-Load with DTP from PSA to first-level-DSO (write-optimized)
3.) Delta-Load with DTP from first-level-DSO to second-level-DSO (standard-DSO). As the activation aggregates all duplicate entries, we are therefore able to deliver a delta to all following data targets (e.g. infocubes)
What we are now wondering about how to use the flag "Only Get Delta Once" which is available in all Delta-DTPs. The help explains it should be used when creating snapshot-scenarios like ours as each request is only delivered once, even if it gets deleted in the data target.
But what other benefit would we have when setting this flag? As I mentioned, the snapshot-scenario also works without this flag...
Could anyone perhaps provide me some more details about this flag and where it should be used?
Thanks & regards
bivision

Hi,
If you select the option 'Only get delta once', then every request in the PSA will only be loaded into the Data target once. For example. If you load a full request into the PSA through an InfoPackage and then load it to the Cube. In a snapshot scenario, when the new full load comes to the PSA you will need to delete the previous request from the cube before loading the new request.
But if you delete the previous request from the cube, and not from the PSA - and if you haven't checked the 'Only get delta once' flag, when you execute the DTP, it will load both previous and the new requests from the PSA to the cube. In order to avoid this you have 2 options:
1. You can delete a request from the PSA after every successful load into the Cube OR
2. You can check the 'Only get delta once' flag in the DTP so that it won't load any request it has loaded into the cubes previously even if it was deleted from the cube.
Using the second option de-couples the PSA maintenance from your regular data loading and also saves you an additional step of deleting the PSA request in your process chain.

How to enable delta for Datasource 0HR_PT_1

Hi BW Gurus,
I am trying to extract records for the period from 01/05/2007 to 01/02/2007. But it is extracting all the full update records instead of extracting only this period records. I checked in R/3 using RSA3. Here it is displaying only 188 records for this period. So please suggest me how to get only this period records or else how can I enable delta to get modified/newly added records.
Plz suggest me as it is urgetnt.

create a selection condition in your existing info package & give the required time period value in it & try scheduling

DTP Indicator Only Get Delta Once: How to handle deleted records in source

Hi colleagues,
I have checked some messages and blogs, but could not find any solution for deleted records in source system.
My source system is not able to delivere delta for my table of interest. So I checked "Only Get Delta Once" in my DTP and made some tests.
It works very well for changes of existing records of the source table.
But, SAP help on this features wirtes:
...If this is not logically possible because, for example, data is deleted in the source without delivering reverse records, you can set this indicator and perform ...
I checked this feature by selecting less data from source at the second load from the same table. But recordmode does not get an deletion flag for the now missing records. So, the indicator "Only Get Delta Once" does not work like BI standard delta mechanism?
What is wrong?
Thanks and regards,
Wolfgang

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. Where we do delta initialisation and delta load?
2. how the data is getting loaded in R/3 while doing delta update?

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.
