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

Difference bw open hub destination and info spoke ???

Hi,
what are difference b/w open hub destination and info spoke ???
Thanks In advance.

Nitin

Hi,
The open hub destination is the object that 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 open hub destination defines the target to which the data is transferred.
An InfoSpoke can extract data in two ways:
1.Full mode (F): the data corresponding to the selection criteria of the InfoSpoke is transferred from the data source into the respective destination.
2.Delta mode (D): records that were added since the last extraction only are transferred in this mode. This is only possible for the source objects InfoCube and DataStore object.
See the below Articles:

What is the difference between Open hub destination and Info spokes

what is the difference between Open hub destination and Info spokes?
Please seacrh the forum before posting a thread
Edited by: Pravender on Aug 16, 2010 11:17 AM

Hi,
When a user initiates open hub extraction by creating an InfoSpoke, behind-the-scenes activity involves OO ABAP which is calling classes to determine each of the different components involved in making the open hub extraction possible. In particular, this enhancement will focus on 2 standard classes: one used to determine file destination name and path and the other to control the user interface of the InfoSpoke which will ultimately allow the user to enter his/her own filename and path.
The open hub service enables us to distribute data from an SAP BW system into external data marts, analytical applications, and other applications. With this, we can ensure controlled distribution using several systems.
The central object for the export of data is the InfoSpoke. Using this, we can define the object from which the data comes and into which target it is transferred.

Info set , info provider and info spoke

Hi gurus plz give me the difference in between info set and info provider and info spoke. and give me what are the prerequisites are needed to process infoset, infoprovider and info spoke?

InfoProvider
An InfoProvider is an object for which queries can be created or executed in BEx

Infoset:
An InfoSet is a special view of a dataset, such as logical database, table join, table, and sequential file, and is used by SAP Query as a source data. InfoSets determine the tables or fields in these tables that can be referenced by a report. In most cases, InfoSets are based on logical databases.
SAP Query includes a component for maintaining InfoSets. When you create an InfoSet, a DataSource in an application system is selected.
Navigating in a BW to an InfoSet Query, using one or more ODS objects or InfoObjects.You can also drill-through to BEx queries and InfoSet Queries from a second BW system, that isConnected as a data mart.
The InfoSet Query functions allow you to report using flat data tables (master data reporting).Choose InfoObjects or ODS objects as data sources. These can be connected using joins.You define the data sources in an InfoSet. An InfoSet can contain data from one or more tables that are connected to one another by key fields.The data sources specified in the InfoSet form the basis of the InfoSet Query.

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.

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 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.
Regards,
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...

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

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.

Best practises for Hub and spoke Metro Etherent network

Hi there,
It is my first MAN deployment. I will use the 6513 as the core switch and the 3550 as the edge switches to the customer.
The customer has 9 locations. The customer asked for interconnection between the 9 locations and his Data center in his HQ.
Additionally his Internet connection is at the HQ too.
What is the best practice to architect this solution addressing security? How I deploy VLANs (like one vlan for the internet, one vlan for each department, one management vlan. Etc)
Any advises

Hi Sam,
Let me add my two cents here, when speaking about MAN deployments the name of the game is MPLS, so I guess you are using the same on your Cat 6500s and connecting your customers on 3550s using Vlans.
Regarding your questions:
a) Upgrading Ethernet to L3 for traffic shaping: This is basically done at 3550, so I suppose that's what you intend to do, plus you will be letting Spokes talk to only Hub site, so inter Vlan, atleast between Hub and each spoke will be required, hence inter valn routing. Other way is to configure P2P circuits between Hub site with Vlan mapping (per spoke) and Spoke sites with Port mapping, in this scenario Inter Vlan routing is not a necessity.
b) Security: This depends on what exact architecure you have deployed, in my case I have simply installed a Gateway router with BGP peering with PEs, a separate VRF alongwith redistribution does the trick.
Hope I addresses the query correctly, let me know if that helped..
Cheers

The best solution? Hub-and-spoke, Peer-to-peer, Multi-cast?

By the best solution, I mean in terms of price and quality (latency, minimum lag, etc)
App type: Video conferencing
Platforms: PC, Mobile (Android, iOS) [If mobile support would reduce performance or increase costs, I am willing to scrap it]
Users: There will be 5 - 30 users logged into the service in the same room at a time. And a maximum of 5 - 7 users in that room will have their webcam's on at any given time.
My main concern is performance, Since I might make it a paid service in the future, I don't think users would pay for something that has a lot of lag or trailing effects.
So I was hoping to get some advice on how I should set it up and pros and cons in respect to LCCS

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

Using DTP we have made the connection and the db table but unble to schedule the data into the db table . can you please suggest as how to schedule the data into the db table from the info cube using open hub ?
Thanks

Hi,
Thanks for the reply. I created a infospoke and destination was database option. Opened the se16 gave the table name which starts with /bic/....(please correct me if i am wrong),then the initial screen of se16 came up with all the fields , but when i executed it, the table is empty.Could you say why it is happening.
