Open hub services

hello Friends,
Can you please tell me what is the use of open hub service ?
As i believe that it is sending a data to flat file ? BUT even though we can also directly send a data through export datasource.
i just want to know is there any additional advantages for open hub.?
Thanks in advance

Hi,
The open hub service enables to distribute data from an SAP BW system into external data marts, analytical applications, and other Non-SAP applications. With this, you can ensure controlled distribution using several systems. The central object for the export of data is the InfoSpoke (SAP BW term). Using this, one can define the object from which the data comes and into which target it is transferred.
Through the open hub service, SAP BW becomes a hub of an enterprise data warehouse. The distribution of data becomes clear through central monitoring from the distribution status in the BW system.

Open Hub services in BI 7.0

Hi Experts,
I am working on BI 7.0 and have a requirement where i have to extract data from a standard sales cube(0SD_C03).I will be using open hub services,but i also need to send the master data attributes along with this into the application file server.
I did the following steps
1) created an openhub destinationa as a CSV file and selected the fields i needed.(Cube has 80+,but i selected only 10 fields for my file).
2) added an infoobject YINVGP which is an attribute of 0Material
3) The transformations were automatically created by the system.
4) Created a tranformation between 0MATERIAL and its Attribute YINVGP and selected the rule type as "Read Master Data".
5) When i click on transfer values to activate the changes,its giving me the following error.
Rule11(Target/BIC/YINVGP Group:01 Standard group) No master data characterstic selected.
Rule(Target Field:/BIC/YINVGP) No source assigned.
Can the experts confirmif i am missing anything?If so please suggest on how to get the master data using open hub services.
Is this possible with open hub services,if so i would really appreciate anybody can pass me screenshots or step by step procedure,as i have not worked on open hub earlier.
thanks in advance

Hi Naga,
I have seen the link you have sent me.It doesnt really help me.But thanks anyways.I am able to create a CSV file,which is not a problem.But my question is can i get the attributes of 0Material to appear in the same file.SAP has provided an option to read master data in the transformation rules,and when i try to use the rule,its giving me an error saying source has not been assigned.
thanks

Open hub service - Cube as source system

Dear gurus,
i am new to open hub concept.
i need to transfer values from my query to a custom table in R/3.
im using bi7.
Questions:
1) i guess pen hub is my solution. is it correct?
2) do i have to transfer values from my cube or can i send values from my query too?
3) i have created openhub service under modelling tab, i have selected target type as TAB. it says database table /BIC/OHZTABLO.
is it correct?
4) then i am trying to create Transformation from open hub ZTABLO to/ BIC/OHZTABLO. ?
in that case it shows that transformation target is DEST- ZTABLO? i mean open hub service is my destination? then what is the source?i am confused in that point.
5) Thanks all!

1) i guess pen hub is my solution. is it correct?
->If u want to transfer dat from yr query then APD (analysis Process designer) will be the best bet to go for. Create APD and schedule it in process chain
2) do i have to transfer values from my cube or can i send values from my query too?
->Using OH(open hub) you have to use Cube as a source,,,you cant use query then.
3) i have created openhub service under modelling tab, i have selected target type as TAB. it says database table /BIC/OHZTABLO.
->ya,correct,there are two ways to do that,,,either u send the cube data to a open hub table(as its happening in yr case) or send it to application server/flat file
is it correct?
--> yes
4) then i am trying to create Transformation from open hub ZTABLO to/ BIC/OHZTABLO. ?
in that case it shows that transformation target is DEST- ZTABLO? i mean open hub service is my destination? then what is the source?i am confused in that point.
---> yr source is InfoCube and target is Open hub table /BIC/OHZTABLO
5) Thanks all!
Than you.

Sample Code in BADI for Open Hub Services

Hi all,
        We have a requirement to extend(add few new fields and populate them using BADI) for the target structure of Infospoke in Open hub services.
I have 2 issues which are stopping us to proceed further.
       1.   I did this by just adding new fields in this change mode of target Structure (didn't used 'Append structure' as while saving and creating T.port request,its popping error like 'Structure not present in TRDIR).I am not able to assign this to any T.request,as of now I have saved it as Local object.How can I assign this to an request?is it possible?.
       2. After putting breakpoint in the BADI I don't see any data in the Importing table.I need some sample code in the BADI which should populate the New fields in the target structure.
It will be great if anyone of you will give us any solution for the same.
Thanks,
Rahul.
Edited by: Rahul Siddi on Oct 12, 2009 3:04 PM

Hello Rahul,
Find the code below with the steps to be implemented.
Enter your infospoke in the edit mode.
- On the Transformation tab set the indicator for the Infospoke with Transformation with BADI so that the infospoke is activated.
- This will take you to the Addin implementation/BADI builder.
- Enter the short text/description for the implementation. The implementation name is always the same as the technical name of the infospoke
- The implementation of the BADI is always filter dependant.
- In the properties tab of the infospoke enter your infospoke under the Filter specifications.
If you do not specify an InfoSpoke under Filter Specifications, then this implementation is valid for all InfoSpokes. This means that this is called up for all InfoSpokes during the extraction.
- Activate your class
- From your interface tab page, double click on the Transofrm Method and you will arrive in the class builder page
- Here you can enter the code
- To do a look up of the master data you have to write a code similar to the one I've given below. This is just an example for looking up material master.
IF FLT_VAL = 'Your infospoke'.
T_DATA_IN] = I_T_DATA_IN[.
Select zstd_cost from /bi0/pmaterial into table T_return
For all entries in T_DATA_IN
WHERE material = T_DATA_IN-material.
...Continue with your code.
Append output from T_return to your output E_T_DATA_OUT
- Activate your method. Return to the BAdI builder. Return to your InfoSpoke.
Check if you missed any of these...

Query regarding Open Hub Services

Hi All,
I am trying to find out if delta extraction is possible through open hub services to a cube which is running daily full load?
To make the scenario more clear:
I have a cube A which is getting loaded on a daily basis (FULL LOAD) but before loading it's deleting the whole data from the cube & loading fresh full load.....this is to get the updated data...
Now I want to set up InfoSpoke for this in delta extraction mode, is this possible???
It would be of a great help if someone can explain how delta mechanism work in open hub services. Any suggestion would be highly appreciated.
Regards,
Kironmoy Banerjee

Can anyone tell me how to extract the master data attached to a field through InfoSpoke?
Ex: I have a field called OIS_BP in one of my InfoCube, I have created an InfoSpoke where I have mapped this filed, but when it extracts data, it will be like 0IS_BP = 1100022, or1100023, 100024 etc, we can not see he master data assigned to it, I mean we can't see the name or address of BP No. 1100022 or 1100023 or 1100024.
Can any one tell me how to add the names with these BP in InfoSpoke?

Kironmoy Banerjee.

BW Open Hub Services...

Hi All,
We need to load Master Data in SAP BW to our SAP CRM system. Someone recommended Open Hub Service in BW (using InfoSpokes). I want to know if it is possible to load the data directly in SAP CRM, instead of using a Flat file generated in Open Hub.
Someone said we can use DB Connect for this, please validate and give me some help links where i can find more info in Open Hub and DB Connect functionality

Infospoke/Open hub services

Guys, I am having problem with creating open hub services. I have to push the data out to csv file. I have been able to give it a name and see the field but what is next? Is there something that I need to push to trigger it to create the file with the data in it? Also please correct me if I am wrong Isn't Infospoke same thing as open hub services? Please let me know.
Thanks,
RG.

Once the file name is given,if its a download to PC then it can only be executed in Foreground(Dialog).
Give necessary selections for the download & execute.
The open hub service allows you to distribute data from a BI system to non-SAP data marts, analytical applications, and other applications.It ensures controlled distribution across multiple systems. The InfoSpoke defines the object from which data is taken and the target into which it is transferred.

Transformations on Datasource for Open Hub Services

Dear all,
I have created a Generic Datasource on a transparent table. Following which have created an Open hub service on this datasource. Now am unable to create the thansformations on this. I encountered the following error "Cannot connect DataSource to an open hub destination ".
Please let me know whether it is possible to generate Transformations for Open hubs on Datasource.
If not, let me know any procedure to populate data from generic datasource.
Kind Regards,
Sunitha

Hi,
connection with an datasource is not possible. But, try to connect the datasource to with an infosource and use the infosource as a source for the open hub. maybe this works.

Alternative for BW Open HUb Services.

Hi All,
We have recently implemented Open Hub Services solution for our clients, where data is being extracted from BW CUBEs to FLAT FILES. Now we came to know that we need separate License to use Open Hub Services. In the current context it's not possible to get the License immediately as it's more than the budget.
Can anybody throw some light, which all other way we can use to get the data extracted to Flat Files other than BW.
We are on BW 3.5
Regards,
Kironmoy Banerjee
Edited by: Kironmoy Banerjee on Nov 13, 2009 11:47 AM

Hi Banerjee,
You can use Analysis Process Designer
In SAP BW, data from various databases from systems available in the company are collected, consolidated, managed and prepared for evaluation purposes. There is often further, valuable potential in this data.
It deals with completely new information that is displayed in the form of meaningful connectivity between data but that is too well hidden or complex to be discovered by simple observation or intuition.
The Analysis Process Designer (APD) makes it possible to find and identify these hidden or complex relationships between data in a simple way. Various data transformations are provided for this purpose, such as statistical and mathematical calculations, and data cleansing or structuring processes.
The analysis results are saved in BW data targets or in a CRM system. They are available for all decision and application processes and thus can be decisive (strategically, tactically, operatively).
Examples of analysis processes include the calculation of ABC classes, determination of frequency distribution or of scoring information.

Hi All,
We are trying to extract data from our BI 7.0 system to our desktop. I could do this easily in BW 3.5 by creating an infospoke and activating it and finally executing it but looks like as usual SAP has changed this for BI 7.0. In BI 7.0 it is completely different and i i did not understand how to proceed. Can anybody provide me with documentation on how to extract a flat file to my desktop using Openhub service.
Thanks
