Error in Open Hub Destination Transport

Hi All,
I am facing the following problem in transporting the openhub destination.
We have created a Open Hub Destination with following settings.
Destination Type :- 'FILE'
We have ticked the application Server name checkbox.
In the server name we have selected our BI Development Server.
In the type of File Name we have selected 'Logical File Name'. We have maintained the details in AL11 and FILE transactions.
While transporting it to our Quality system, it throws an error saying it does not recognize the server name (which is true, the server name is different in quality system).
Needed your guidance if there is any setting like source system conversion where it would change the name?
Also if you could guide me regarding the best practices to transport the entries we have created in AL11 and FILE it would be realy nice. I did a search on this in SDN and could not find any useful stuff for my case.
Thanks in advance.

Hi,
Your TR is failing, may be because in your target system, application server file system is different.
go to transaction AL11 and check that. If same folder structure is not available, get it created, or go to RSA1 and try changing your infospoke settings to point to the application sever file as in your target system.
You have to point this path to Q server.

Open Hub Destination-Third Party Tool

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 ,
sasidhar gunturu

Some light at the end of tunnel for sure...
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 via 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.

Use of Open Hub Destination to load data into BPC

Hi Gurus,
I want to load the data from SAP BI to BPC (NW version), using Open Hub Destination. I want to know few things about this.
1) What method should I use? Should I use Destination as Flat Files or Database tables? If Database tables, how can I use this data in the tables in BPC?
2) If I go for Flat Files, which is saved in the application server of BI, how can I import those files to BPC and use it using Data Manager?
3) Also, in case of Flat Files, there are two files which are created. One is the control file and other one is the data file. How can I use both of them? Or can I just use data file without header?
Your replies will be much appreciated.
Thanks,
Abhishek

Hi Anjali,
I can use the standard data manager package from BI to BPC, if the CSV file is available in the BPC Server or in case if I am directly extracting from BW object, InfoObject or InfoCube.
But, since I will be using Open Hub, the output of this can be in a Database Table or a CSV file, preferably in SAP Application Server. In such cases, how can I use the Database table or CSV file in the standard Data Manager Package?
Thanks for your reply.
Abhishek

Open Hub Destination question

Hi,
We want to be able to extract data from a cube and would like to use Open Hub Destination for it. We also want to extract deltas.
The question is ..
Should we be making a single info package for this with delta capability ..
or 2 separate info packages .. 1 for full mode and another for delta mode.
Regards
Vandana

Hi,
Yes what you said it is write
from which cube do u want to retract the daat that cube will be the source
first create the open hub in RSBO tcode and
in open hub destination select aht and create the transformation between the table( to where u want to export)
then create the DTP between the cube to the table
and directly u can use the delta DTP first all the records will come and later onle delta records will be updated.

Open Hub Destination error

Hi,
I am working on Open Hub (first time ofcourse). And performing following steps:-
Modeling>Open Hub> InfoArea> Create Open Hub Destination> Output to File .csv. field names>DIrectory> activate> Create transformation> activate Transformations>Create DTP..Here I am getting an error that destination Open Hub is not active.
Can anyone please tell me am i missing any step here?
Thanks

Hi...
Always bear in mind that the OHD, once created, should be saved and activated, before creating any transformations or DTPs for it.
And each time the OHD is changed, all the objects corresponding to it... (The transformations and the DTPs) should be activated.
Hope this helps.
Thanks

DTP Delta request for open hub destination.

Hi expert,
As you know, In BW 7.0, open hub destination is used for open hub service, and you can create tranformation/DTP for the destination. and in some case the DTP delta is enabled.
my questions are
1) in the context menu of open hub destination, I did not find something like manage, which could list all the DTP request executed for this open hub destination..but for normal infocube or ods, you can find a list.
2) if the DTP could enable the delta, where can I delete the latest delta request, and have a new load..
3) I assume the DTP could be excuted with batch integrated with process chain by process type 'DTP', right ? if the destination type is third party tool, can it also be integrated with process chain ?
4) can give some obvious difference of InfoSpoke and open hub destination in terms of advantage and disadvantage..
Thanks a lot for the feedback.
Best Regards,
Bin

To view the data in open hub destination

Hi all,
Can anyone help me out how to check the data in open hub destination file.
These are the details:
Destination: File
Type of file : Logical file
Application Server file name : XXXXXXX
If it was file name, i know it has to be checked in AL11 with directory name and file name.
Here its a logical file name. Which is the directory corresponding to this?
Thanks,
tinkugeo

Hi,
Question: "Are all the logical files are saved in the home directory DIR_HOME?
Please correct me if I am wrong"
Ans: When you create an Open hub destination using Physical file, the file will get created in DIR_HOME directory (by default) in AL11
And for locating the physical path in AL11. Go through the below link. it gives ans to all your ques

Open hub destination with datasource as the source

Hi,
I am trying to use the new features of BI for open hub destination where you can use datasource as the source for extraction.
I have created an infopackage, loaded data to PSA and from there to open hub destination via the DTP.
When I try to execute the DTP, I get the following error:
<b>Datapackage processing terminated.
Error in substep
You are not authorized to use this transformation.</b>
I have been able to use the DTP to load open hub destination targets with datastore and infocubes as source.
Also when we turn on the security trace, it doesn't fail anywhere.
Has anybody faced a similar problem?
Any help appreciated,
Thanks,
Payal.

I have created to OHD - one for a 3.5 data source and one for a 7.0 data source (both are different data sources). While creating DTP for the 7.0 data source, it did create a default mapping for transformation.
But I still get same error in both cases.
When I create the DTP, it tries to create a transformation. But I get an information message :
Exception CX_RS_MSG occurred (program: CL_RSBK_PATH==================CP, include: CL_RSBK_PATH==================CM00I, line: 16).
I can still activate the DTP and when I run it says I don't have authorization to this transformation.
I think there are issues while creating the transformation, but I don't know what!

Open Hub Destination transports

Hi Experts..
We have crated Open Hub destinations to pull data from ODS to DB table in BI 7.0. But while transport the transformations for OHD are failing with transformation becoming inactive with error messageu201D Target ODSO ZODS*** does not exist" But the ODS is present in QA system and is in active version.
So can any one pls help me to know the proper sequence for Open Hub Destination transport and the necessary objects to be captured in the request? Currently I had captured OHD, transformation and DTP in the same request.

Umesh.

Send the OHD in one request, transformations in one request, then DTP in another request.
When club transformations & DTP together it fails in my experience.

Open hub destination issue

Hi,
In our project we have Client Instance (eg: BWPD) and Application server (eg: BWPRD) defined for load balancing.
We have created open hub and assigned destination server BWPD.
When i execute the DTP manually in BWPD, it runs succesfully.
However, the same DTP when placed in the process chain fails with error message :
No Such File or Directory
Could not open file D:\usr\sap\BWPD\A01\work\Material on application server
Error while updating to target ZXXXX.
Options Tried:
Schedule process chain in the background server BWPD (same server which has been mentioned in Open hub dest) still DTP failed.
Tried with Application server it failed.
Tried with HOST as option it failed.
couldn't make out what is going wrong. Any thoughts ?
Regards.

Hi there,
found that doc quite useful.
Maybe could shed some light to your issue.

Also, what OS do you have?
is the Syntax Group accordingly created ?

Error in Transporting Open Hub Destination Objects

Hi Experts,
When i transport the open-hub destination to Quality server from development, the error No Rule Type Exists occurs while activating the transformation.
The objects are transported but transformation & DTPs are inactive.
Please assist as this is for the first time Open-Hubs are being transported in my system.
Any help will be greatly appreciated.
