Extract data from BW ODS to external application

Hello,
We have the following interface challenge:
We need to interface data from an ODS to an external application. The request for this data comes from the external application and contains selection parameters.
The datasets are small and the responses need to be fast.
How to do this?
We do not want to use Query_data_view, it is not performing and contains too much meta data
Preferably we define a webservice either in BW or XI/PI that receives the request and send back the answer.
What are the possibilities/best practices?
Brokered or non-Brokered?(using XI or PI or just using an BW webservice)
Do we need to publish the webservice to an UDDI?
How do we extract the data from the ODS, via a Function module? If so i guess that FM can be made externally available and callable from XI/PI.
Does ehp1 provide more fucntionalities in this area than 7.00?
Does PI provide more functionalities than XI in this area?
Do we need proxies for this?
Thanks for any insights

Tom,
How to do this?
External application (SOAP request) <-> PI <-> SAP BW (ABAP Proxy response). Make both - web service and proxy - sync.
Preferably we define a webservice either in BW or XI/PI that receives the request and send back the answer.
What are the possibilities/best practices?
Web service will be defined in external application, proxy will be created in BW. Search on SDN for the detailed steps.
Brokered or non-Brokered?(using XI or PI or just using an BW webservice)
If you have PI as the integration hub, then prefer using PI.
Do we need to publish the webservice to an UDDI?
Not required.
How do we extract the data from the ODS, via a Function module? If so i guess that FM can be made externally available and callable from XI/PI.
Call the function module / any other extraction program from the proxy. No need to make FM externally available.
Does ehp1 provide more fucntionalities in this area than 7.00?
Does PI provide more functionalities than XI in this area?
Do we need proxies for this?
PI 7.1 EhP1 SP 6 is the latest, so it will definitely provide more functionality over older versions.
Yes, use proxy at BW side.
Hope this answers all your questions.

Need to extract data - from USB 2.0 external disk

Ive tried Data Rescue II to no avail. I cant afford to buy another tool to use such as FileSalvage.
I was hoping somebody else in the Mac community knows of a freeware/shareware or otherwise inexpensive tool that can extract data....
Cheers and TIA

just for anyone following this thread, who may be experiencing a similiar issue here are more facts.
This is a USB 2.0 type external USB drive in a small plastic enclosure. Its got a 3 year warranty from manufacturer Simpletech.
It worked fine for 6 months. It appears to have failed - it was never accidentally erased. Ive used it weekly to backup my MacBook Pro.
Suddenly, this Simpletech 250Gb drive stopped being accessible. You would see the the (two) partitions mount, and correct volume names. One partition was made big enough to handle backing up a MBP- im my case a 100Gb partition. The latter partition was what was left over, or nominally, 150Gb. Upon connecting the USB 2.0 cable, you would see the volumes mount, with correct volume names and contents, but upon clicking (say a folder of text documents), the item would simply disappear from view. Further clicking on other items - say folder full of my pet pics, folder of music, folder full of pics of stuff I have for sale) those would disappear too.
Repair tools such as Disk Utility did and still do see the volumes and contents. But nothing more can be done to view or access any data within them.
Side note: DU has the "vulnerability" of not forcefully unmounting volumes - and will state when it cant do so. Unmount is a command and a process used by OSX to modify disk contents. The drive or partition icon would and should disappear from your desktop (momentarily), then DU can do its thing, hopefully to repair whatever is wrong. Same idea for erasing, unmount would still be needed. But if the partitions dont unmount via DU, you might be tempted to give up. Fortunately, you can go to Terminal and issue a command such as:
sudo umount -f /dev/get name of your disk from DU - get info (such as disk2/s5)
while this Terminal way of issuing unmount may work (and did for awhile for my faulty disk) no utility was able to repair my drive in any way shape or form. No erase command, no format, nothing nada.
So Im stuck with wanting to RMA this defective drive back to the manufacturer but have no way to erase the data.
Tried putting close to gigantic speaker - that didnt work at all.
Any suggestions ?
Simpletech has said they will replace it if I send it back. My data is seemingly trapped on this drive !
I tried:
Tech Tool Pro
Drive Genius
Diskwarrior
Data Rescue II
to no avail.

Error while extracting data from ODS using Infospokes - URGENT

Hi all,
I am extracting data from an ODS using infospokes and nothing fancy, no selection criteria but I am getting an error message saying
Syntax error in row3(-> long text) Msg id = "RG" and msgno is 102
Any ideas on how I can see what is the exact error and how to debug this?
thanks
Sabrina.

Hi Sabrina
service.sap.com can help you getting the details of your mesg.
I found one OSS note suitable to your mesg. So just check out OSS note # 671097. I hope this note will be some help to you. If not go and chk in the OSS you can find some more.
Here is the note details also
<i>Symptom
Error message RG102: 'Syntax error in &1, row &2 (-> long text)' appears in the request log of an InfoSpoke.
Reason and Prerequisites
The data source is an ODS object and the extraction mode is 'delta'. The cause of the error message is that the ODS extractor is unable to select the request ID (InfoObject 0REQUID) from the change log of the ODS object. However, the request ID is mistakenly provided in the field list of the ODS object on the InfoSpoke maintenance screen. --
Solution
Delete the 0REQUID InfoObject from the field list of the InfoSpoke and activate the InfoSpoke. As of the patch mentioned below, the request ID in the template tab is no longer provided.
BW 3.0B

To provide information in advance, the notes mentioned above may already be available before the Support Package is released. In this case, however, the short text still contains the words "preliminary version".
Refer to note 110934, which contains information about BW Support Packages.</i>

Performance issue while extracting data from non-APPS schema tables.

Hi,
I have developed an ODBC application to extract data from Oracle E-Business Suite 12 tables.
e.g. I am trying to extract data from HZ_IMP_PARTIES_INT table of Receivables application(Table is in "AR" database schema) using this ODBC application.
The performance of extraction (i.e. number of rows extracted per second) is very low if the table belongs to non-APPS schema. (e.g. HZ_IMP_PARTIES_INT belongs to "AR" database schema)
Now if I create same table (HZ_IMP_PARTIES_INT) with same data in "APPS" schema, the performance of extraction improves a lot. (i.e. the number of rows extracted per second increases a lot) with the same ODBC application.
The "APPS" user is used to connect to the database in both scenarios.
Also note that my ODBC application creates multiple threads and each thread creates its own connection to the database. Each thread extract different data using SQL filter condition.
So, my question is:
Is APPS schema optimized for any data extraction?
I will really appreciate any pointer on this.
Thanks,
Rohit.

Hi,
Is APPS schema optimized for any data extraction? I would say NO as data extraction performance should be the same for all schemas. Do you run "Gather Schema Statistics" concurrent program for ALL schemas on regular basis?

How to extract data from ODS to non-SAP system

Hi,
Can anybody tell me, step by step, how to extract data from ODS to a non-SAP system?
Is it possible to do it without programming effort? And is there volume limits for this kind of extraction?
The non-SAP system is an unix system.
Thanks in advance
Ella

Ella,
You can look at it from the concept of a BADI / Infospoke
Extract the data from the ODS to a Flat file / RDBMS using an infospoke. I am not sure as to how the infospoke loads data into the RDBMS ( did it very long ago ) but then you can push it into an RDBMS and I am sure it will be system neutral.
Hope this helps...

Extract data from SAP and send to external system via Webmethods & IDOC's

Hi,
We need to Extract data from SAP and send to an external system via Webmethods middlewear using IDOCs. I have never used webmethods before and would like to know more about how to implement this scenario. I have used IDOCS in an EDI scenario before but not used it along with WebMethods.
Any pointers would be of great help. Thanks

If you have already ABAP programs /BAPI's in place then try to develop RFC interface and write some back ground programs to scheudl BAPI's and develop scenario but you need to implement error handling , data validation in PI mapping level.
or
take help from ABAPer to design in ABAP like writing Proxy program to pull data and send it PI.
if you are dealing with master data bit risky(correctness) but can be achived using PI.

Extracting data from iDoc tables

Hi,
I need to extract data from idoc segments from the database tables EDIDC and EDID4 for which the idoc status is 51 and to save all this data in an external file.
For example, I need to check all the iDocs with WPUBON01 base type and if the status is 51 then I have to query the ARTNR field from E1WPB02 segment and to save idoc number and ARTNR in an excel file.
Can anybody help me or give me some example?

How do i repair or recover data from a corrupt USB external hard drive that does not show up on my Mac desktop or disk utility

How do i repair or recover data from a corrupt USB external hard drive that does not show up on my Mac desktop or disk utility?
Last night i was using my external hard drive, for some reason the folder just closed and i couldn't find it on my desktop.
After googling solutions, i found it in the disk utilities, i clicked on the 'repair' button many times, but it said the 'error...' message.
So i ejected it to try again, now when i connect the USB external hard drive it doesn't show up on my desktop or disk utilities.
I really just want to either repair or recover the data on it because it literally has everything (documents, work files, photos etc) on it,
I downloaded an application to recover my files but it needs the USB to at least show up.recognise it which mine doesn't.
I know i should've backed it up on another USB, this definitely teaches me for next time to back up all my files.
Are the files lost forever or can i recover them by going to a shop or using a software?

Thank you for responding.
This might sound stupid since i'm not really knowledgeable with Macs,
but since all my files were moved from my mac computer to the external hard drive,
is it possible to recover those files through my Mac - like recovering deleted files?

Extracting data from Z-table from SAP R/3 to BW

Hi all
I want to extract data from a Z-table from SAP R/3 system to Bw system. Currently I am on BW 3.5. Since it is a Z table I dont have a standard extractor for it & I dont knw how to create it. Can anyone provide me with the step-by-step documentation of how to extract data from a non standard SAP table????

Hi
You need to create Generic Datasource on the Z-Table you want to get data from
Go to RSO2 transaction to create generic datasource .
You need to give technical name of datasource under datasource type you want and click on create. Then you can give descrption and Application component under which u want see the datasource,
enter the z table name under view/ table and save.
here you can click on check boxes to make fields hidden or selection fields.

How to Extract data from a Request management tool to Apex to avoid working on Excel reports

Client uses a ticketing tool,I donot know what is the database for the tool,but I would like to know the best way to extract data from the tool to pex so that we can eliminate working on Excel reports.These excel reports are basically the open request log,resolved tickets,aging tickets etc,currently we work on many excel reports,can we achieve this in Apex ,if so how do we achieve this.Then we would like to use this report and prepare multiple charts,how the above two requirements can be mapped.

A very important function for the system will be - one sends an email in certain format to a dummy email address, then some data will be extracted from the email based on the pre-defined format and inserted into the database my APEX application is using.
Any idea on how I can make it happen please? I agree that this is not really an Apex question, but a more general PL/SQL question.
There are many approaches, all boiling down to one of these two:
1) Push: Some process in the mail server sends/forwards information to your database when new mail arrives.
The language/tools used to do this, and the way it would connect to your database, depends on your environment (what is your operating system? mail server? existing middleware/tools? security protocols used? etc.).
2) Pull: Some process in the database contacts the mail server and polls for new information.
Ie. some PL/SQL code would communicate with the mail server. Again, it depends on your environment (what is your operating system? mail server? existing middleware/tools? security protocols used? etc.).
For example, if you are using Exchange 2007 or newer, it has a web services API:
http://msdn.microsoft.com/en-us/library/dd877045.aspx
The challenge here will be to build the correct SOAP requests from PL/SQL, and to handle the security protocols used.

How to extract data from custom made Idoc that is not sent

Hi experts,
Could you please advise if there is a way how to extract data from custom made idoc (it collects a lot of data from different SAP tables)? Please note that this idoc is not sent as target system is not fully maintained.
As by now, we would like to verify - what data is extracted now.
Any help, would be appreciated!

Hi,
The fields that are given for each segment have their length given in EDSAPPL table. How you have to map is explained in below example.
Suppose for segment1, EDSAPPL has 3 fields so below are entries
SEGMENT          FIELDNAME           LENGTH
SEGMENT1         FIELD1                   4
SEGMENT1         FIELD2                   2
SEGMENT1         FIELD3                   2
Data in EDID4 would be as follows
IDOC           SEGMENT                          APPLICATION DATA
12345         SEGMENT1                        XYZ R Y
When you are extracting data from these tables into your internal table, mapping has to be as follows:
FIELD1 = APPLICATIONDATA+0(4)        to read first 4 characters of this field, because the first 4 characters in this field would belong to FIELD1
Similarly,
FIELD2 = APPLICATIONDATA+4(2).
FIELD3 = APPLICATIONDATA+6(2).
FIELD1 would have XYZ, FIELD2 = R, FIELD3 = Y
This would remain true in all cases. So all you need to do is identify which fields you want to extract, and simply code as above to extract the data from this table.
Hope this was helpful in explaining how to derive the data.

How to Extract data from a transaction..

Hi All
There are some transactions and report programs which are used daily to produce some results and the requirement is to extract that data into BW
so how can we extract information from a transactions and programs
Any help will be really appreciated and ofcourse rewarded ...
Regards
Lisa

You can use the following methods
Method 1:
1> Create another ABAP program with logic to calculate all the fields, but instead of writing the result data to screenm, it should store it in a internal table and pass it to the extract structure.
2>Create a InfoSet query based on your ABAP program and use that InfoSet
3> Create a DataSource based on this InfoSet query and extract data from the DS to you ODS/Cube
In this method there is no Intermediate storage used.
Method 2:
1> Modify the report/transaction program to store the required data into a Transparent Table (u can create one from SE11) in addition to displaying on the screen.
2> Create a View on this transparent table (from SE11)
3> Create a DataSource on that view and extract data from that into your ODS/Cube.
Here, the required data is stored in the Table in addition to the DataTarget.
But, to implement either of these solution, you will need a decent ABAP knowledge. Else, it will give you a tough time!
Good luck!

Sree
