BI & Oracle XI data exchanges using WEBServices (into both sides)

Hello,
Would you be so kind and give me suggestions.
We have:
BI 7 server Oracle Exchange Infrastructure Oracle DB server
Our client wants to implement this data exchange solution:
Scenario A: i have load data to BI from Oracle DB
My steps are: from BI i have to call WEBService from Oracle Exchange Infrastructure when Oracle Exchange Infrastructure calls WEBService from Oracle DB and Oracle DB returns data set to BI via Oracle Exchange Infrastructure.
How to schedule job for calling WEBServices from Oracle Exchange Infrastructure? What have i configure in BI?
Scenario B: Application based on Oracle DB wants to get data from BI
Steps are: Oracle DB calls WEBService from Oracle Exchange Infrastructure when Oracle Exchange Infrastructure calls WEBService from BI and BI sends data to Oracle DB via Oracle Exchange Infrastructure.
BI offers Open Hub Service for data distribution from BI, but I didnt find description how to distribute data using WEBServices.
Is is possible to implement Scenario A and Scenario B in BI with standard tools.
Could you give me detailed answers(step-by-step what I have to do)?
Thanks in advance.
Best Regards,
Arunas Stonys

Arunas,
Quite an interesting landscape....
Also what do you mean by standard tools ?
Option A :
You can use the XML datasource for the same and once the XML data source is called , the data enters the Delta Queue in the BI server and from there you can use the normal infopackage / real time daemon to load data into your cubes / DSO. The XML datasource works on SOAP and this has to be supported by the Oracle XI.
Option B:
Slightly more trickier since you are hitting the BI server directly....
I am not sure if an infospoke can be a web service but some of the ways this could be done is :
a. Have an Func Module which acts as a web service and have that FM return the data
b. Have SAP XI inbetween to do the same
Also on the landscape- depending on the nature of data loads / data requests - if BI-Oracle is more - you can look at having SAP XI there instead....
Arun
Hope it helps....
P.S I would also suggest that you post the same in the Enterprise SOA forums / enterprise web services and people like Karthik Iyengar , Durairaj etc can respond to the same in a much better way that what I am able to give you right now...

SAP 4.7 XML data exchange using XSLT

Hello All,
Hopefully the right place to post such article but here goes any way.
My project involves producing XML files and then reading them back into to SAP internal tables. I am ok with writing SAP data to external XML file but reading it back in is causing a lot of head scratching.
I am able to double click the XML file and it launches Ok in Internet Explorer.
I am also able to debug the xslt file from within SE80 and the correct output is displayed.
However, where I am trying to read the contents of the xml file via the Call Transformation procedure call my output table is not getting populated but instead I am recieving an error message saying the following is not correct:
xmlns:sapxsl="http://www.sap.com/sapxsl
but the above line is placed automaticlly in the XSLT when you create a new one from within SE80.
I am new to SAP ABAP development so not sure what's exactly wrong.
Any help on this issue will be greatfully appreciated. Thanks in Advance,
Wasif

Look in the Reports Builder Help:
If you want to use lexical references in your SELECT clause, you should create a separate lexical reference for each column you will substitute. In addition, you should assign an alias to each lexical reference.
Does adding the column alias solve the problem?

How to insert encrypted data by using blowfish into mysql database

Hi
I have encrypted data using blowfish algorithm . And i tried to insert that encrypted data into mysql. it was stored but i dont know that it stores in the same encrypted formate
When i am trying to get the encrypted data from the mysql database and decrypting that data i am getting errors.
Exception are like
input length should be multiple of 8 bits
or Given block are not properly padded
and when i am displaying the data using system.out.println ();
the string is not similar to the string which is in database.
what is the problem how can i solve my problem
thank you

It sounds like your column is a VARCHAR so you need to Base64 or Hex encode the cipertext bytes before putting them in the database.

DATA exchange using XML using ABAP

Client is having requirement of sharing data with Third party using XML files and this needs to be done using ABAP and changes in XML structure are highly likely in the future and structure is very complex around 100 fields corresponding to an account , three ways are there as far i am aware of :-IXML library,Simple transformation and XSLT ,
confusion is which way to follow as Performance constraints are also there and Simple transformation had failed in the past with large amount of data,
I would like to know what is Industry wide accepted way of doing this in SAP ( XI is out of scope here ) using ABAP and which one will be the best regarding quality of design and performance

Hi,
what about the Client Data Bag? http://help.sap.com/saphelp_nw70ehp1/helpdata/en/68/322a9261c54e51b7965f86aac3dae2/content.htm

How to insert data values using Poplist to both block items....

Hi,
I have created a poplist which should return a sequence(which is stored in a db table) and a description .
The sequence(stored in table) is of number datatype and the description is of varchar2.....
I have created the required record group as:
rg_id := Create_Group_From_Query('TEXNIKOS_GROUP', 'select eponymo , to_char(seq_code_ergazomenoy)
                                                       from ref_ergazomenos,ref_eidikothta
                                                       where ref_ergazomenos.code_eidikothtas_type_id=ref_eidikothta.seq_code_eidikothtas
                                                       order by 1');
   status := Populate_Group( rg_id );
   if (status = 0)
     then
      POPULATE_LIST('MOD2_KLISI_VLAVIS.TEXNIKOS_FNAME','TEXNIKOS_GROUP');
   end if;The field 'MOD2_KLISI_VLAVIS.TEXNIKOS_FNAME' is the description i described above ... and whereas this block item is filled with the selected poplist... the sequence - the code of the db table- is not.....
Is it possible to do so.... ????
NOTE: i use Dev10g.
Many thanks,
Simon

I have two block items:
seq_code_ergazomenoy: number datatype , db item , invisible
eponymo:varchar2 datatype , non db item , visible
How to fill these both block items using the written record group...?????
Now , only the "eponymo" block item is filled but not the required "seq_code_ergazomenoy"....
In other words.... is there any manner to do the column mapping of the two selected columns (in the dynamically created record group) to the two block items....????
Thanks,

Will indexes be used on the both sides of the join?

SELECT * FROM emp a, dept b WHERE a.dept_no = b.dept_no
Assume we have bitmap index on emp (dept_no) and we have binary index on dept (dept_no), will both the indexes be used for searching when equated?

I had looked the Explain plan, but it is taking only one index (index on dept (deptno)).
I tried giving hint for the other index, still no change in explain plan.
Will the other index be used while joining and not shown in explain plan?Care to show us your test case?
And your Oracle version?
Here's mine....

Retrive data from two tables into one internal table.

Hi SDN,
I am downloading the Assets data from two tables ANLA,ANLZ.
there is a common field ANL1in both tables and i have to retrive the data by using anl1 into the internal table.
can you please send me the SELECT Syntax for this probl.....
Thank you & Regards,
Manoj

Hi manoj,
Please see the following sample code. But kindly don't use join as it may hamper ur performance. No trouble in using two select query.
data: begin of itab occurs 0,
        BUKRS like anla-BUKRS,
        ANLN1 like anla-ANLN1,
       BDATU like anlz-BDATU,
        end of itab.
select anlabukrs anlaANLN1 anlzBDATU into corresponding fields of table itab from anla inner join anlz on anlaanl1 eq anlz~anl1 where (logexp).
Please come back for any clarification.
Thanks and Regards,

How to receive and upload data into Sharepoint using webservice in BizTalk (without using sharepoint adapter).

Hi,
I have a requirement to receive files from sharepoint and upload files to share point.
So is there anyway we can achive this using webservices in BizTalk (without using sharepoint adapter)
Thanks in advace

I do not have a sample flow... but if you refer to the samples where these web services are used then you'd be able to translate those code samples into BizTalk flows.. For e.g.:
http://msdn.microsoft.com/en-us/library/office/ms429658(v=office.14).aspx refers to returning list items. When you add generated items to your BizTalk for SharePoint Web Services, you'd get the schemas (xmlDocs in the sample) which you'd instantiate and
call.
When dealing with lists, you will need the GUID of the list so you need to do a GetLists call first and then get the GUID for your specific list from that. You will also encounter CAML which is what is used to query and get List Data.
Have fun.
