Open hub and Infospokes

Hi ,
can anyone explain me the selection parameters of infospoke in production system .
is there any FM developed by SAP ??
please let me know how can i proceed
Maid

Hi
You can do that in ABAP code but i am not sure if there is any FM related to it
Step1
Create a TVARV variable similar to the selection parameter of your Info Spoke.
Step2
Code an ABAP program so as to pick the value of the TVARV variable and change the values of the parameter in the table RSBSPOKESELSET. This is the table which stores the selection set based on which you want to restrict your results.
Step3
Once you execute the program, the selection parameters would be changed.
Step4
Now, you execute your Info Spoke. It would have the new selections maintained by you in the TVARV variable.
Try this and do let me know

Open Hub Vs Infospoke

Hi All,
In BW 7 We are using Open Hub & previously using Infospoke in BW 3.5. My question is in infospoke we have the flexibility of using BADI but in Open Hub we dont have that option. can we still use infospoke instead of Open HUB. Are there any advantages of open hub over infospoke.
Thanks,
Kiran.

Hi,
The open hub service enables you to distribute data from an SAP BW system into external data marts, analytical applications, and other applications. With this, you can ensure controlled distribution using several systems. The central object for the export of data is the InfoSpoke. Using this, you 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.
Functions
BW objects such as InfoCubes, ODS objects, or InfoObjects (attributes or texts) can act as open hub data sources. You can select database tables or flat files as open hub destinations. Both a full and a delta mode are also available as the extraction mode.
Components of the Open Hub Service
The open hub service is made up of the following objects:
InfoSpoke
The central object for the data export is the InfoSpoke.
The InfoSpoke defines the following:
u2022 The open hub data source from which the data is extracted
u2022 The extraction mode
u2022 The open hub destination into which the data is delivered.
In addition, you can also select which data selection is to be extracted from which InfoProviders. This selection ensures that a destination for different points in time from the same InfoProvider can be supplied with data for different selection criteria using a delta. The selection set is freely configurable as long as extraction has not taken place in the delta mode. Once it has, this no longer applies.
Open Hub Data Source
BW objects such as InfoCubes, ODS objects, MultiProviders and MultiProviders and InfoObjects (attributes or texts) can function as open hub data sources. If you use an InfoCube with non-cumulative key figures as a data source, refer to the note regarding the settings on the Selection tab page in Creating InfoSpokes.
Extraction Mode
An InfoSpoke can extract data in two ways: in full mode (F) and in delta mode (D). See InfoSpoke Extraction Mode.
Open Hub Destination
Database tables (from the database in the BW system) and flat files (CSV) can act as open hub destinations. See also Extraction to Database Tables and Extraction to Flat Files. You can extract the data from a database to a non-SAP system using APIs with a third-party tool. See also Extraction to Non-SAP Systems.
The open hub destination includes all information about a target system for the InfoProvider data: type of destination, name of the flat file or the database table. It also contains a logical target system. The logical target system is used to structure the individual open hub destinations in the open hub monitor. The open hub monitor groups the requests according to logical target system, open hub destination and InfoSpoke. By specifying a logical target system, you get a better overview of the individual open hub requests.

Open Hub and Reporting

In Open Hub we send the data from Data Target to the Excel Sheet and in reporting also we generate the report in excel sheet.what is the difference between the two.

Chandu.

Hi Eswar,
Welcome to SDN !!!
It is the open hub service that enables you to distribute data from an SAP BW system into external data marts, analytical applications, and other applications. With this, you can ensure controlled distribution using several systems. The central object for the export of data is the InfoSpoke, whereas, when you execute report you get the output in Excel but you cannot make any changes to the data but it can be used to analyze.
Hope it helps...

Deleting DTP based on Open Hub and Remote Cube

Hi All,
i have created a DTP delta for my Open Hub to load a flat file from a remote cube.
i have done some load test request but it doesn't work (no data in my file .csv), i have created another full DTP with others parameters and it works successfully.
now i want to delete my Delta DTP but the system return me a message like this:
DTP_4IDT4BXV29E1N0MWINKCWO60B cannot be deleted at the moment (see long text)
and in the long text i have:
Message no. RSBK037
Diagnosis
You want to delete a delta DTP that has been successfully used to load requests from the source into the target. If you delete the DTP, you will also delete the information on the source data that was successfully transferred. As a result the source data would be transferred again, if you create a new delta DTP that links the same source with the same target.
System Response
The system terminated the delete operation.
Procedure
You have two options:
1. Delete all the requests loaded with this DTP from the target and then delete the DTP.
2. Do not delete the DTP and continue to load deltas using this DTP.
i tried to see the requests loaded with the delta dtp and i have deleted one but there are another requests that i can't deleted.
i have deleted the delta dtp from my transport request.
how should i do to delete definitivily my delta dtp?
thanks for your help
Bilal

Do not delete entries out of table RSBKREQUEST.
To delete your DTP, you may use program RSBKDTPDELETE. Give the technical id of the DTP as the input parameter.

Open Hub and Informatica

Hello All,
We are facing a situation, we need to extract data from SAP BW and load it in informatica,
We have created a openhub.
The data in the targets are large , we are able to load the data into open hub quickly ( 6million records in 15mins), but when the data is transferred in to informatica the time taken is huge ( 30-45 rows/sec) when we ran a trace we couldn't find any reason why the data is extractin so slow.
Request you to please let me know what all checks can I do to find the bottleneck and what kind performace improvement I should think of doing.
Regards,
Ravi

Hi Kumar,
Informatica has a connector for SAP BW, integrating as a 3rd Party RFC destination via open Hub.
In the process chain to load the open hub you also need to include a custom ABAP program (distributed via the Informatica DVDs), which is mainly of event logging and informing the listener service on the Powercenter side when the load to the open hub destination table is finished.
We will be using the same method, although we're just in blueprinting at the moment and haven't doe a POC yet. I've got a document, contact me for more info.

Steffen

Open Hub and Info Spoke

Hi all,
We have a bunch of Info Spokes created in our production and we want to delete them based on last used date.
Can anyone tell me in which table in BW are the Info Spokes stored
Also like aggregates where we can find out last used is there any tables where we can see when was the Info Spoke last used. I know we can check this at Monitor but when we are talking about hundreds of Info Spokes it can be very tedious to check from monitor
would really appreciate your answers
Surya

Hy surya,
so far I know, the useability will not be recorded in the database. Eventually you may find some info in the InfoCube for technical content, but your question gives me the feeling, that you have a modelling problem, because normally if you have your infoSpokes in process chains you better track the useability. Further, When having so much InfoSpokes as you told, could be that most queries are similar?
Anyway, if you use a file as target, you can see the last creation date. I hope you can follow the relation between InfoSpoke and the target.
Cheers
Paul

Master Data Extraction through Open Hub services(InfoSpoke)

Hello,
I need your help on this issue,
Here is my scenario...
I want to extract Master data from BW (Info Object) as a file and put it in a server then later that can be picked up by some other deprtment for their process. This process has to be automated to run on a weekly basis.
I know this can be done through a InfoSpoke(either ATTR or Text) and Process Chain but I want both attributes & text data in a single file because through InfoSpoke we can get either ATTR or TEXT data in a file.
1)Is there any way we can have both TEXT and ATTRIBUTEs data in a single file.
2) Also what are the options to transfer the file from a BW app server into another non-BW server?
Currenty I created a BEx query against a InfoObject, ruuning a report and sending them the file manually. I want to automate the process.
I would appreciate if you could give me input on the above.
Thanks
BI Consultant

Hi,
The simpleset way to do is to create a ODS with the required columns and map it to your TEXT and ATTR. Then you could use either a Query or a Info Spoke to extract data how ever you want it. Since you are using master data it would have been validated, so you don't need to use a reportable ODS, which takes time to activate the data. So create a info set on top of the ODS and do a simple query if you want to use it. If you want to automate completely and deliver the output as .CSV file to the destination server you may have to do little bit more and that will involve some serious ABAP work. The simpleset would be have a ODS 'Non reportable' and extract the data using info spoke.
Let me know if you need more info.
Thanks,
Alex.

Open hub destination & infospoke

hi experts,
what are the major differences between openhub destination & Infospoke
Thanks
Swaroop Kumar Noothi

There is no difference in both of them
both are used to transfer data to Non-application systems.
the thing is info spoke is the concept used in prior to BI 7.0 versions.

Hi
u can use the DTP and transformations to load this data to Openhubservice from BI system
Create Data transfer process (DTP) by right clicking the master data attributes
In extraction tab specify extraction mode ( full)
In update tab specify error handling ( request green)
Activate DTP and in execute tab click execute button to load data in data targets.

Open Hub Extraction

Hello
I am doing a open hub and sending data to a file. Now in the file i want to maitain the header line(description of field) for the fields i am sending to the file. How can i do that. Please can someone explain me a little bit in brief.
thanks

Hi,
Once u run the Infospoke, it will generates two files, data file and schema file. The data file contains the data and the schema file contains the deader or the structure of the Infospoke. So if u want to maintain the header in the data file, u just copy the list of InfoObjects name and paste it on the header file.
Thanks & Regards

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
Thanks & Regards,
Vikas

We use infospoke to archive the data from the datatarget into a flatfile or a database table.
To create the infospoke select the tools menu -> open hub destination.
Give the technical name and click on create.
In the general tab select the type of the object and the name of the object from which the data is is to archived.In the destination tab select the file or the dbtable to which you want to move the data, and give the destination path.
In the infoobjects tab select the objects you want and the order in which the file is to be generated.
If you want to extract the data selectively ,you can give selections in the selections tab.
Then activate the infospoke . Click on execute .The data will be moved to the destination in specified format
