Open Hub API

I am trying to export data from BI (version 2004s, SP 11 on an Oracle DB) to an external SQL Server database using OpenHub's third party API.
Can anyone give me an example on how to use the API? My ABAP skills are not very solid, so the more details the better.
I have looked at the help files and I think I understand the process on a high level. I know that I first have to create an RFC connection to the database, then extract the data to the Open Hub tables in BI. How can I now pick up this data using the Open Hub API?
Any example around this API would be helpful.
Thank you,
Dennis

Open Hub 3rd party tool - API not returning data table

I am implementing a 3rd party tool to get data from BI using the Open Hub Service.
I have my server running and the API functions are working somewhat, but I have two problems.
When I get notified by BI (RSB_API_OHS_3RDPARTY_NOTIFY), the REQUESTID field is always 0. Why? This should be the request id of the Data Transfer Process; I can see this id in BI.
The second problem is when I make the call to read the data (I hard code the request ID), everything comes back fine, except the table is empty. I know it's not empty because the DTP said it create a table with many rows and I can see them in BI. Why is the table empty?
Any help is appreciated. Thanks.
Tim
PS: I'm using SAP JCo to implmenet the server and the API. And I'm using BI 7.0.

I am not sure I should continue: I am not an expert with the use of these API - in fact I have never used them:-)
This is in case the discussion would help you:
My understanding is that the 'green' status is the status of the 3rd party tool. Only when the 3rd party sets a 'green' status will extraction proceed. The third-party can choose to stop extraction by setting a 'red' status.
See the link below:
http://help.sap.com/saphelp_nw70/helpdata/EN/43/8dea54c4e273e2e10000000a1553f6/content.htm
Guess all these APIs are geared for automatic processing - another link:
http://help.sap.com/saphelp_nw70/helpdata/EN/59/90070982d5524b931ae16d613ac04a/content.htm
RSB_API_OHS_3RDPARTY_NOTIFY: This function module has no source code - the code needs to be implemented in the 3rd party tool to do whatever is required with the parameters provided. The import parameters required have to be supplied to it.
That's it, I am retiring:-)

Open hub Destinations - Third-Party Tools As Destinations

Dear all, below is the SAP Help process flow steps. I am quiet clear of all the steps except the APIs. Where do we define these APIs? When it says "You use API RSB_API_OHS_DEST_SETPARAMS to define the parameters for the third-party tool that are required for the extraction" where do I use it? Is it in the 3rd party tool? or is it in SAP BI.
If it is in 3rd party tool, where in 3rd party tool. Do I need to write as code ? or would I have an option in the 3rd party tool?
If someone can help me with Microsoft connector using Microsoft SQL Server 2008 Integration Services packages to SAP BI that would be helpful.
Where in Microsoft SQL Server 2008 Integration Services packages can I use/put this APIs? Any help Plzz
If it is in SAP BI where in SAP BI do I have to use these APIs? Any help is highly appreciated
Regards,
KK
Process Flow:
Extraction to the third-party tool can be executed as follows:
       1.      You define an open hub destination with Third-Party Tool as the destination type.
       2.      You create an RFC destination for your third-party tool and enter it in the definition of the open hub destination.
       3.      You use API RSB_API_OHS_DEST_SETPARAMS to define the parameters for the third-party tool that are required for the extraction.
       4.      You either start extraction immediately or include it in a process chain. You can also start this process chain from the third-party tool using process chain API RSPC_API_CHAIN_START. The extraction process then writes the data to a database table in the BI system.
       5.      When the extraction process is finished, the system sends a notification to the third-party tool using API RSB_API_OHS_3RDPARTY_NOTIFY.
       6.      The extracted data is read by API RSB_API_OHS_DEST_READ_DATA.
       7.      The status of the extraction is transferred to the monitor by API RSB_API_OHS_REQUEST_SETSTATUS.

It's been a along time since i worked with open hub, but here goes:
The Third Party tool needs parameters or switches to work correctly. Think of the old DOS commanda the "/a" "/b" suffix.
The APIs are simply a way to pass these parameters from the BW source to the Third Party target.
If your tool does not need them, don't worry about them.

Inconsistency with ZPMSENDSTATUS for Open Hub Destination

Hi Experts,
I dont know you have come accross this scenario but I will apprecaite all your advice.
We have APO 7.0 and we are using the BW component to extract data to informatica.
Our environment is as follow
SAP SCM 7.0 SP8
Informatica PWCD 8.1.6 hot fix 13
1.we have created 5 chains with similar variants for ZPMSENDSTATUS
2. Each variant relates to a folder and workflow to be executed within informatica
3. When we execute the chains only two work correctly all the time and 3 fail
the 3 that are failing are failing within the ZPMSENDSTATUS when running API RSB_API_OHS_DEST_SETPARAMS. This is odd since the other two only differ on the workflow to be executed and obviously on the Open Hub destination. Can anyone provide some advice on this?
thanks,
Nat

Hi Maruthi,
thanks for your response but here are the details for the variants that are working and failining
working:
DEST: < here we have the RFC that relates to the logical system and the program id which is also included in saprfc.ini>
INFPARA: AERO/APO:WF_SAP_APO_PART_PLATFORM_ABP2_BGA:S_M_SAP_APO_PART_PLATFORM_ABP2
CONTEXT: OHS API
OHDEST: <OHDS defined as target>
Failing:
DEST: < here we have the RFC that relates to the logical system and the program id which is also included in saprfc.ini>
INFPARA: AERO/APO:WF_SAP_APO_PART_PLATFORM_ABP4_ATR:S_M_SAP_APO_PART_PLATFORM_ABP4
CONTEXT: OHS API
OHDEST: <OHDS defined as target>
So you see, they all target the same folder only different workflows. Still it works for the first and not for the second.

Open Hub third Pary extraction in yellow state forever

Hi,
Would appreciate any assistance in this regard.
Here's the situation:
1 - We have third party open hub extraction setup.
2 - All settings are fine : RFC destination, transformations, Open hub.
3 - Now the issue is that we have a third party system which is data stage and teradata.
4 - Now they trigger a job which in turn starts the PC in BW.
5 - This PC has 2 steps only. The start and the DTP.
6 - This DTP loads data from Info-object attributes to Open hub (basically a table).
7 - The DTP technical status is green but overall status stays yellow.
8 - Now I know that for 3rd party, we have several APIs and here's my understandin:
When the extraction is finished and technical status is green, BW notifies 3rd party through RSB_API_OHS_3RDPARTY_NOTIFY.
Then the 3rd party checks the data through RSB_API_OHS_DEST_READ_DATA.
Then if data is fine, the 3rd party send confirmation through RSB_API_OHS_REQUEST_SETSTATUS and the overall status turns to green.
Now I do not understand what's wrong because all of the above mentioned should complete automatically.
We have other openhubs with same RFC destination and they are completing successfully. Just for the information: We have recently moved to SP 10 on EHP1.

Debanshu

Were you able to solve this? I am also facing exact same problem.

Open Hub External System

Hi,
I have a basic requirement to extract data out of Open Hub into an external Oracle database. I have read previous threads online on this topic, but still have a couple of questions that are not clearly answered.
Firstly, my client complies with all licensing arrangements to use Open Hub.They do not want to use flat files and they do not have access to tools like the Microsoft Connector described in many online blogs.
Secondly, my client would like BW to kick off the process chain, load into an internal BW table, and then raise a trigger to the external Oracle database to come and "pull" the data from the newly created table. I am new to working with API's, but I read about standard API's been available to achieve this, but I would like some simple clarrification:
- In my Process Chain, after I load the Open Hub data into the internal table, I want BW to use the API RSB_API_OHS_3RDPARTY_NOTIFY to tell the external system it's ready to pull the data. Reading the docu about this API, it seems like this needs to be initated from the external Oracle database. Is this correct (I would hope BW could do this) ? And if so, I dont know if my client has these API's on their Oracle system. How do I ensure they do ? I imagine they are freely available, but since I am not a DBA, and do not have access to someone who can tell me or not, I would like to know what the standard procedure for API communication is here. An example or white paper showing the API (with parameters) for a real life scenario would be ideal.
- If the above does not work, even though they say the Microsoft connector tool can be used for Oracle, I am hesitant to use a Microsoft tool, when surely Oracle has their own free tool to do this - or can the Microsoft Connector integrate directly with an Oracle database ??????
- When we refer to the term "Third Party Tool", does this mean a ETL tool like Informatica, or a connection tool like the Microsoft Connector, or the external database like the Oracle database in this example ?
Any clarrification with the above would be most appreciated. I do not have access to a BW system yet, so I would like to know some of the details before I propose a potential solution.
Thanks,
BWPerson

dear all,
can any one guide me as to how data(master data in particular) from bw can be transferred to oracle data base using open hub destiantion.is rfc connection between bw and third part tool enough,do we have to maintain the same structure in third party tool before executing DTP and how can this be done??
i am now able to transfer data from bw into a flat file and also to data base (bw) and not aware of the this functionality-third party tool .any light thrown on this area is welcome and points will be awarded ,
thanks ,

What's the difference between Infospokes and Open Hub Destination in BI 7?

I understand the API that a 3rd party tool uses to get data our of BW using infospokes. Is it the same API that a 3rd party tools such as MS-SSIS uses? Supposedly that software only communicates with an OH Destination and not Infospokes. So apparently is does use a different API. If that's the case, where can I find documentation on that API for OH Destintations?

Open Hub Destination (OHD) replaced InfoSpokes as of BI 7 SPS 6, for Open Hub Service. Existing InfoSpokes can be used still, but it's recommended that any new retractions be created as an Open Hub Desitnation, because it exposes more functionality (e.g. Transformations and functionalities with DTPs).
Here's a document on [Open Hub Service - 3rd Party Integration|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/com.sap.km.cm.docs/library/icc/bw-ohs%20open%20hub%20service%2c%20third-party%20integration.pdf] (see Page 7). Hope this helps.

Sending data directly from BW To Oracle DW via Open hub Third party tools

HI All
We need to send data from SAP BW 7.0 to Oracle 11g DW. The requirement is to pass data through open hubs. So we wanted to explore the option of directly passing the data from BW to Oracle using third party tools. So i tried to gather information on the third party tools and came across list of APIs and some pointers on creating a RFC through SM59. But dont know how to do it or what parameters to pass. Could you please point me in the direction or list me step by step detailed instructions as to how I can achieve this?

Hi Amit..
I can see the following will make things work for you.
1) BODS.
2) PI ( XI).
3) BI7.0 to FTP and from FTP you to push these tp your oracle system..

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 licence

Gurus
I am trying to use open hub service in BI 7.0 and in these case need to distribute data to other non-sap systems.
so do i need to have license for this ???
thanks

If you extract data from your SAP NetWeaver BI to a non-SAP system, you have to license this scenario - no matter which tool use for the extraction, e.g. Open Hub Destination, listcube, any BI API, Analysis Process Designer or Excel download.
Note that a licensed BI user may download to Excel for her/his own analysis purposes without any further license costs. Distributing Excel workbooks to non-SAP BI users for personal reporting purposes requires Information Broadcasting license, not Open Hub license.
Hope it Helps

Error while assigning constant to infoobject in open hub transformation

While assigning constants(in rule details) to infoobject in a transformation in a open hub I am getting an error "The Object Name is not allowed to be empty"
Can anyone tell my why this is happening? What should I do now?

Hi,
In the transformation, have you connected that rule to any target field of your destination? If not, then do that and then try to create the routine.

Open Hub: How-to doc "How to Extract data with Open Hub to a Logical File"

Hi all,
We are using open hub to download transaction files from infocubes to application server, and would like to have filename which is dynamic based period and year, i.e. period and year of the transaction data to be downloaded.
I understand we could use logical file for this purpose. However we are not sure how to have the period and year to be dynamically derived in filename.
I have read in sdn a number of posted messages on a similar topic and many have suggested a 'How-to' paper titled "How to Extract data with Open Hub to a Logical Filename". However i could not seem to be able to get document from the link given.
Just wonder if anyone has the correct or latest link to the document, or would appreciate if you could share the document with all in sdn if you have a copy.
Many thanks and best regards,
Victoria

Hi,
After creating open hub press F1 in Application server file name text box from the help window there u Click on Maintain 'Client independent file names and file paths' then u will be taken to the Implementation guide screen > click on Cross client maintanance of file name > create a logical file path by clicking on new entiries > after creating logical file path now go to Logical file name definition there give your Logical file , name , physical file (ur file name followed by month or year what ever is applicable (press f1 for more info)) , data format (ASC) , application area (BW) and logical path (choose from F4 selection which u have created first), now goto Assignment of physical path to logical path > give syntax group >physical path is the path u gave at logical file name definition.
however we have created a logical path file name to identify the file by sys date but ur requirement seems to be of dynamic date of tranaction data...may u can achieve this by creating a variable. U can see the help from F1 that would be of much help to u. All the above steps i have explained will help u create a dynamic logical file.
hope this helps u to some extent.
