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.

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 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

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

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.
[Creating Open Hub Destination using a Logical file to extract the data|Creating Open Hub Destination using a Logical file to extract the data]
Also, what OS do you have?
is the Syntax Group accordingly created ?

I am getting an dump while executing open hub destination?

I did happened to delete a filed in the open hub and then activated and re-ran it i am getting the following error!!
error analysis
You attempted to assign a field to a typed field symbol,
but the field does not have the required type.
open hub is active, dtp is active and transformations is active too but still the same!!
Can anyone advise me on this!!

Hi Paleri,
According to the
thread which has the same error message, the issue may be caused by incorrect RCF settings. Could you double check your RCF connection configurations such as DNS settings?
If it is not the case, please also make sure you have installed the correct version of Microsoft Connector for SAP BW.

I have two open hub, one is fine ,but the rest one always get this error. Help..........

Thanks! I checked my ID and found that i have the role to access this folder.
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.

How to create Fixed Length Flat File from Open Hub in BI 7.0

My requirement is to produce a Fixed length Flat file by Open Hub destination. My Open Hub has four fields. Now the requirement is to create another extra field in Open Hub which will contain all of the four fields value. In addition to that the fields should be fixed length that means if for any field no value is there and the field length/type is CHAR4 then 4 spaces should be there as the field value. SO, basically the Open Hub output will be single field which will contain information of four fields.
How to get this using End Routine of Transformation (from DSO to Open Hub) ?

Hi,
You can map the four input fields to the new field in the Open Hub, and change rule type to "Routine".
For example, if your source fields are called "first", "second", "third" and "forth", the ABAP routine could be similar to:
DATA: l_t_1 TYPE C LENGTH 4,
      l_t_2 TYPE C LENGTH 4,
      l_t_3 TYPE C LENGTH 4,
      l_t_4 TYPE C LENGTH 4.
IF source_fields-first IS INITIAL.
l_t_1 = '    '.
else.
MOVE source_fields-first TO l_t_1.
endif.
IF source_fields-second IS INITIAL.
l_t_2 = '    '.
else.
MOVE source_fields-second TO l_t_2.
endif.
IF source_fields-third IS INITIAL.
l_t_3 = '    '.
else.
MOVE source_fields-third TO l_t_3.
endif.
IF source_fields-forth IS INITIAL.
l_t_4 = '    '.
else.
MOVE source_fields-forth TO l_t_4.
endif.
CONCATENATE l_t_1 l_t_2 l_t_3 l_t_4 into result.
In the example, the program uses four blank spaces if any of the fields has no value.
Additionally, if non-initial values in input fields could be shorter than 4 characters (if the input fields have no fixed length), you could use STRLEN to evaluate if it is necessary to add blank spaces to complete the fixed length of 4.
I hope this helps you.
Regards,
Maximiliano

Open Hub, Delta Transformation

Hi All,
Thanks in advance for your help. I am extracting data from a DSO to a flat file using an Open hub and a delta DTP. The problem I have is that if there is no delta (i.e. zero new/changed records) since the last time the open hub ran, my file is not cleared.
For example, If I ran the DTP in the morning and received 100 records, the open hub creates a file in the UNIX directory with a 100 records. However if in the evening I run the DTP again and there are no new records, the file is cleared, and remains with the 100 records. This is causing a problem down the line because the data is sent twice.
Is there anyway that the DTP can output blank files? or can the file be cleared out in a different step in the process chain?
your help is very appreciated.
Thanks

Hi,
This note should correct your problem: 1111259
Summary
Symptom
You extract data using a Delta data transfer process (DTP) to an open hub destination of type 'File on application server'. If the source does not contain any new data, the existing file is not deleted.
Reason and Prerequisites
This problem is caused by a program error.
Solution
SAP NetWeaver 7.0 BI
Import Support Package 17 for SAP NetWeaver 7.0 BI (BI Patch 17 or SAPKW70017) into your BI system. The Support Package is available when Note 1106569 "SAPBINews BI7.0 Support Package 17", which describes this Support Package in more detail, is released for customers.
In urgent cases, you can implement the correction instructions as an advance correction.
Hope this helps.

Open Hub Extraction

Hello
I am doing a open hub and sending data to a file. Now in the file i want to maitain the header line(description of field) for the fields i am sending to the file. How can i do that. Please can someone explain me a little bit in brief.
thanks

Hi,
Once u run the Infospoke, it will generates two files, data file and schema file. The data file contains the data and the schema file contains the deader or the structure of the Infospoke. So if u want to maintain the header in the data file, u just copy the list of InfoObjects name and paste it on the header file.
Thanks & Regards
