Open Hub Destination Table Vs File

Hello Experts,
We have a requirement to send data from BW to 3rd party system every day. In the Open hub destination we have two options for the target.
1. Table
2. File
ETL tool like Informatica will extract the data from table or file into 3rd party sytem.
Which way is the best in performance and maintenance?
Thanks in advance
Sree

Hi,
If you follow the delta mechanism then table is good. You can also go for File not a problem. See the both eamples in the following articles.
If you use Fiels then go for Application Server option, i.e. AL11 becasue no one can change teh files in this location, you can restrict the authorizations.

Open Hub Destination with Flat File - Structure file is not correct

Using the new concept for Open Hub destination (NOT an InfoSpoke).
Output is to a Flat File. Remember that when output is to a flat file 2 files are generated: the output file and a structure file (S_<name of output file>.CSV)
The Output file structure corresponds to the structure defined in the Open Hub destination.
However, the S_ (structure) file does not reflect the proper structure. The S_ file lists all fields sorted in alphabetical order based on the field name, instead of listing all fields in the correct order that they appear in the output file.
I have not found any settings that I can modify for the S_ file. When using InfoSpokes the S_ file is correct and I do not have to do anything.
The issue is that the S_ file cannot be used to describe the output file. This is a problem.
Anyone knows a solution to this issue? The goal is to get the S_ file to reflect the proper structure.
I could not find any Notes on this. Please do not send general help links, this is a specific question.
Thank you all for your support.

Hi,
However, the S_ (structure) file does not reflect the proper structure. The S_ file lists all fields sorted in alphabetical order based on the field name, instead of listing all fields in the correct order that they appear in the output file.
As I know and checked this is not the case. The S_ file has the fields in the order of infospoke object sequence ( and in transformation tab, source structure).
I would suggest you to control it again.

Help required for Creation of process chain for Open hub destination(table)

Hi Experts,
I am working on creating process chain for the open hub destination which is targeting data transfer into Table. Which is then push to SAP PI.
2.) Steps to create a process chain for OHD????? Not knowing and even after that
3.) What are the steps for Pushing it to PI (I mean we have generated client proxy also) But need to know ABAP related to trigger process chain
please need your expertise and knowledge. Well atleast with the point 2 I need BI experts help...
Regards,
[Gaurav Patwari|http://gauravpatwari.wordpress.com]

Hi Gaurav,
Creating Process chain for OHD.
1. Go to RSPC-> Create a astart variant.
2. Click on process typesin the menu. Fourth from the left. Under this go to LOAD PROCESSES AND POST PROCESSING option.
3. The fifth option is "DATA EXPORT INTO EXTERNAL SYSTEMS". Click on that.
4. Click on F4 and choose your infospoke name.
5. Press the RIGHT button.(if it asks for variant, create a new variant in the same small window besideswritting bar).
6. Join the START process and the 2nd process via dragging.
7. Now add your required other processes.
The general process chain processes are :
1. Start.
2. Delete Indexes (if data loaded to cube).
3. Load process.
4. Delete duplicate request (if it is a full load in cube).
5. Create Indexes.
Hope it helps.

Open hub destination problem - .csv file is empty

Hi everyone,
I am trying to extract data from our BW system using Open Hub Dest. to a .csv file
DTP runs successfully means show total no. of records but when I see in AL11 then records are not in .csv file that is .csv file is empty.
How to figure out the problem?
Best regards
Ahmad

@Jagadeesh:
if I correctly understood you, you mean to say that first I should run DTP and save to an excel file to see if it shows data or not. This i think is not possible; as when we create OHD then 'Destination Type' we can choose among 'DB table', 'table' and 'third party tool',
so if I choose 'Table' then 'File Name' is .csv file (same name as the OHD) and can change it to .xls file
@Arun:
have permission to write in the folder
Do you mean creating OH to a Database Table?
in DTP I have a filter on a Characteristic, when its 1500 records then it works (data is in .csv file) but when 3500 records then .csv file is empty
no error message, no log
Regards
Ahmad

Open Hub Destination table structure update

Hi,
     I created a open Hub detsination and activation created the table and populated the data in the table and have a view over the table.
     I need to add few more fields in the open hub and when I did that and activated again , it is supposed to change the table structure adding the new fields that were added in the open hub.
   The activation was successful but the table structure still stays the same.I didn't see the new fields in the generated table.
   Anyone having similar issues.
Thanks in advance

We deleted all the related objects from Staging and production and re transported them from Development as though they are being sent for the first time and that works.Tough this approach is not good we need to use it as I didn't find any other solution

Open Hub Destination - csv files

Hi all,
I nedd to send information through Open Hub Destination from a cube to a File in a server. But the Open Hub Destination is originating 2 csv files instead of 1: one of the files has just the name of the fields that will be in the columns and the other file only the data in the columns.
There is an alternative to generate through Open Hub Destination, only one file, with the headers in the columns?
Can you explain to me how to do it?
There are other options to generate csv files, automaticaly from cubes,and send them to other applications?
Thanks a lot.
Regards.
Elisabete Duarte

Hi,
To send information from a cube to applicatin server thru OHS,
two files will be formed while using OHS. One which will be saved inthe aplication server and for other u should give the path. For downloadin the file to the applc server, in the destination tab, select applcn server option and transform it
Hopeit helps

Text Values in Open Hub Destination

Hi ,
Can anybody tell how to extract the text of particular info object using open hub destination into a file.
For ex data is loaded from sales billing cube, ship to customer code is extracted , but need ship to customer name . how to extract this in open hub destination using BI 7.
In queries , we use display key and text then get both key and text values. similar like that is it possible to get in open hub or not.
Thanks .

Hi Uppala,
Following are 2 approaches to achieve this
Approach 1:
1. Create info spoke which will extract data from cube to data base table (do not use file)
2. Create one more info spoke which will extract master data text to data base table (again do not use file)
3. Create join on both the data base tables.
4. Write a ABAP program which will create a file based on the joins of tables.
Approach 2 :
1. Create multiprovider on cube and master data info object
2. Create info spoke based on the multi provider, that will extract data to flat file
For 2nd approach u have to put certain filters to avoid unwanted rows
Regards,
Ajinkya

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

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

Multiple data sources to open hub destination ??

Hi,
Is it possible to assign multiple data sources to open hub destination?
At present we are FTP'ing a file to users. Users need one more field added to this file. The information for this field belongs to another ODS. I checked the infospoke but it does not accept multiple data sources.
Any ideas?
Thanks!
Edited by: BI Quest on Sep 4, 2008 8:12 PM

You can create multiple transformations for open hub destination. Create destination of open hub destination to be file on application server and then use transfer mechanism to transfer files to desired destination.

Hi Guys,
             I have a requirement where i need to down load the data from my BW cube to R/3.For this i am using Open hub destination.
While creating the open hub destination we have option called RFC Destination(in that i have selected destination as my R/3 system).When i execute my DTP it is saying the load is successful and it is showing the no.of records transfered.
But i am not able to find where this data is getting transfered From BW cube to R/3 system using open hub.

Hi Friends,
I have one Query on WDJ. Here I have two requirements.
I have done click on u201CExport Excelu201D Button that data was download into Excel file Now my requirement is click on Save Button that file will save into (/exchange/CED) this path of R/3 System.
CED -
>is R/3 System ID
Under System id we can save this file.
Here EP Server and R/3 Servers in Diff Systems.
I was write codeing
InputStream text =      null;
     int temp = 0;
     try
     File file =      new File(wdContext.currentContextElement().getResource().getResourceName().toString());
//       String File = "abc.xls";
//       String file = "anat" + ".xls";
     wdComponentAPI.getMessageManager().reportSuccess("File::"+file);
     FileOutputStream op =      new FileOutputStream(file);
//       FileOutputStream op = new FileOutputStream("D://usr//sap//BPE//"+file);
//       FileOutputStream op = new FileOutputStream("D://KumarDev-BackUp//"+file);
     wdComponentAPI.getMessageManager().reportSuccess("op::"+op);
     if (wdContext.currentContextElement().getResource()!= null)
     text = wdContext.currentContextElement().getResource().read(false);
     while((temp=text.read())!= -1)
     op.write(temp);
     op.flush();
     op.close();
//        path = file.getAbsolutePath();
     path =      "/exchange/CED/"+file;
     wdComponentAPI.getMessageManager().reportSuccess("path:"+path);
     catch(Exception ex)
          wdComponentAPI.getMessageManager().reportSuccess("ex.printStackTrace()");
My Req is that file will saved in this path (path =      "/exchange/CED/"+file; )

Then i found that our Q system have two servers, A and B, for open hub i should run my process chain in system B, but i forgot that, so i got error. After i changed to sever B, i re-active my open hub and DTP, then re-fresh the process chain and re-executed it again, the error disappeared.

Open hub destination as ECC table

Hi All,
Is it possible to create a open hub destination to an ECC table?
Can only see the option for csv, tabke and thrird party.
Thanks,
Nick.

Alright Arun,
Yeah I was thinking of that. If we have 100's of R3 tables where all the data needs extracting, then cleansing then imported to another R3 system would you consider doing this in BI or would you go R3 to R3???
Cheers,
Nick.
