So Guru's please let me know is this possible in infospoke to store delta data either in file or table.
Thanks,
Ekka

Hi pradeep
You can store the delta using Info spokes in files.
Please go through the below articles

Delete the initialization of delta on open hub table

HI Gurus
I have loaded data from cube to open hub table using DTP with full update, later on i have loaded the data using a DTP with delta update. Now i am thinking that delta has been initialized on the open hub table, so now want to delete the initialization of delta on the open hub table. It would be great if some one could send me the response.
Thanks
Rohit

Hi Sam,
If I understand you correctly,
You have removed your Initialisation by going InfoPackage --> Scheduler --> Initialization Options for Source --> Removed the Request
Then you did Init without Data Transfer
Then you have the option from init withoout Data transfer to Delta in InfoPackage and Loaded the Data.
Check in the Process Chain the InfoPackage you have mentioned in the selections may pointing towards Init load instead of Delta.

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.

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

Data Services - Open hub read - No Open Hub DTP error

Hi,
I have created a open hub destination in BW (7.0 SP21), created transformation, DTP and process chain. In Data Services (3.2) I have created flow, job etc. and every thing seems to be as expected. However when I start the job in DS it terminates with an error:
1136 5624 BIW-230334 13-11-2009 12:28:22 Process Chain <ZTEST2> of Open Hub destination <ZTEST> at SAP system <.......> no more contains Open Hub DTP. Please reimport the Open Hub destination to execute the appropriate Process Chain.
I've tried re-activating everything in BW and also re-importing the OHD in BW, but nothing works. I've even tried to re-create everything from scratch. The process chain I've created do indeed contain an Open Hub DTP.
One addtional question: I've activated the process chain, but do I also need to schedule it in BW (like you do with e.g. process chains for time points to be used in Broadcasting)? Note, I've tried both scheduling/no scheduling and does not work either way.
Any ideas/suggestions?
Thanks in advance,
Jacob

You must implement following SAP Notes in SAP systems in order to make Data Services Open Hub functionality work correctly:
SAP Note 1270828 : (Open Hub Process chain is not imported into Data Services repository).
SAP Note 1294774: (Open Hub import failed - when you call the module RSB_API_OHS_DEST_SETPARAMS, th system tries to open a GUI)
SAP Note 1330568 version 3: (This note has fixed "Process Chain <ZTEST2> of Open Hub destination <ZTEST> at SAP system <.......> no more contains Open Hub DTP. Please reimport the Open Hub destination to execute the appropriate Process Chain").
SAP Note 1079698 - 70SP16 (Enable check box "Automatically Repeat Red Requests in Process Chain" in the DTP Execute)
SAP Note 1346049: (Error 028(OSOH): Request <n> cannot be locked.)
SAP Note 1338465 #with 1293589 as pre-requisite: (The ABAP/4 Open SQL array insert results in duplicate database records.)
SAP Note 1342955: (0 data records transferred)

Open hub Table deletions

Hi all,
I am using an open hub and out put as DB . for delta load form DSO in open hub level i selected technical key so it will maintain the entire history of delta changes but for performance reason i should delete the DB after some time .
note:
I don't want to select the option deletion data from the table
Thanks and regards
uday

HI,
Deleteing Data in Tables depends on your requirements, generally there are options i.e. Append or Overwrite data, or Delete.
For reference keep data in Tables after some time/days/weeks you can delete the data in tables using some ABAP code. So you write simple code to delete the data in that Table and execute that program whenever you want to delete the Data in Tables.
For, some references see in below url in Open Hub Destination section

Master text data in Open Hub

Hi All,
I am working on BI 7.0 and am currently working on Open Hub. I have to extract data from a cost center infocube, but i also need to send the master text data for certain fields along with the infocube data into the file server.
Is this possible with open hub services,could someone please provide me with a step by step procedure to this one.
I have been following a similar thread
Nav. Attrib in Open Hub 04s
Please let me know if it was succefully implemented by someone.
Regards
Dipali

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

Ajinkya

Filtering data in Open Hub

In the info-spoke definition, is there a way to make filter values dynamic in the 'Selection' tab. For example, we have an info-spoke that we extract data to monthly - by fiscal period. Since the Production instance is a closed system, we cannot change the filter value directly in Production, but would have to change it in Development and transport it up to Production. I have read in some SAP documentation that there is a plan to have variables available as selection criteria but it was not mentioned when this would be available. Thank you for your help.

Hi Celine,
   Why you want to change the selections.... why cant you use delta...?
   If you want to do selection accourding to ur fiscal year create a BADI and create a variables from system data. and restrict according to ur selection.
   for more info check at www.service.sap.com/bi -> infoindex -> O(Open hub destination).
I hope this helps.

Can we download aggregate's data through open hub?

Hi,
Can we download Cube Aggregate data to file or infospoke? If yes then send me detailed steps?
Ritika

Hi Ritika,
Thier is no staright forward, way of extracting data from Aggrgates table, as the OHD can be build on following Object types: Datasource, infosource, DSO, Infoobject & infocube.
So you can it a try by creating a generic datasource on the desired aggregates table, and use it in a Open hub destination.
Hope this helps,

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
