Create webdynpro appl. to fetch data from r/3 system without bapi?

Hi all,
Please suggest regarding this issue.
I have to create a iview which display all the authorized link access to the user form the sap r/3 system and display it in portal.
like when we login to sapr/3 system we get a catalog of all that we can access at left hand side in a catalog ... in that similar way i need to show this iviewcatalog on the portal and the next iview at right side of this catalogiview should open the transaction which is clicked in the first iview,but the first iview should be there it should not disapper.
This first iview should be there from the login time of user to this logoff time...
no matter what ever transactions are carried on the right hand side iview...
and one more thing there is no existing bapi for the system.
I think this can be done using webdynpo with abap ,but not sure nor I know how to do it .. please help
Please tell me is it possible to do and if yes then how can this be done .
It will be helpful if anyone provide steps to do or any dounment to refer.
Please help it urgent...
Thanks
Gunja

2. click over view in left tree .
3. Click on wizard Icon
4. Extract Standard Tree
5. YOu will get screen , form etc option s
6 . Take screen and specify u r program name and all .
<a href="http://picasaweb.google.com/parrysdn/UntitledAlbum/photo#5124419458543968274">Try this out</a>
option two .
1. Make ITS template of tht transction .
for this may u can see ITS threads.
2. call that ITS from web Dynpro ABAP
other than that ...there is some sample example avilable where they have demostrated how some Tcode can be called from web Dynpro ABAP .In that example u specify Tcode ...it will execute it . But I dont remember its name ..Sorry

Hi Detlef / Gowtham,
Now I am able to fetch data from flat files from OWB Server as well as OWB Client.
One way I have achieved as suggested by you
1) Creating location on the OWB Client
2) Samples the files at client
3) Created & Configured external table
4) Copy all flat files on OWB Server
5) Updated the location which I created at the client.
Other way
1) Creating location on the OWB Client
2) Samples the files at client
3) Created & Configured external table
4) Copied flat files on the sever in same drive & directory . like if my all flat files are on C:\data at OWB Client then I copied flat file C:\data on the OWB Server. But this is feasible for Non-Windows.
Hence my problem solved.
Thanks a lot.

RFC fetching data from table which is not commited

Hi Experts,
               I have a query regarding commit work.Below is the RFC that i have written
FUNCTION ZBAPI_CREATE.
*"*"Local Interface:
*" TABLES
*"      IT_ZABAP_RFC STRUCTURE ZBAPI_RFC_STR OPTIONAL
*"      RETURN STRUCTURE BAPIRET2 OPTIONAL
CALL FUNCTION 'ZBO_BAPI_CREATE'
TABLES
   IT_ZABAP_RFC       = IT_ZABAP_RFC
   RETURN             = return
Break-point.
DATA lt TYPE TABLE OF ZBAPI_RFC_STR_MAIN.
CALL FUNCTION 'ZBAPI_SEARCH_RANGE'
* EXPORTING
*   IS_STR        =
TABLES
   ET_TAB        = lt
*   RETURN        =
ENDFUNCTION.
here in first RFC call i am creating a record in ZTABLE , and then at break-point
i check the ZTABLE where it does not create any record because data is not commited into ZTABLE upto this point, but just after it i have written code for fetching data from ZTABLE but i am able to get this new record in lt.
Can anybody please explain that from where this serach RFC is providing data because inside serach i am simply selecting data from ZTABLE.

Abhishek Bajpai

Hi Thomas,
                 Thanks for reply , i checked in ZTABLE ,before search RFC call data is not there but if i commit explicitly only then it is showing data in ZTABLE. Actually my requirement is different -
I have two RFCs 1. Create 2. Search , Now from web dynpro user will call first Create RFCs but at this point it should not insert record in ZTABLE and just after it user will call another search RFC and in this search he should be able to get these newly created records.
I want to have the functionality which a user gets when working with normal database front end like SQLPLus for Oracle. In these scenarios we see that whenever user does any insert or update the data sits in the table but still it is not committed. So there he fires Select query he sees the inserted data. But if he logs off from SQL PLUS and then logs in again, and fires Select query he does not see the data as it was not committed. I want a similiar functionalty in which if user inserts the data through Create RFC and fires the Select query through Search RFC then he can see the newly Created data also even though this data is not committed.
Although if i call create RFC in update task it will not update ZTABLE but in this situation , if user will call search RFC he will not be able to get newly created records.
So my requirement is that i should be able to get those records which are not commited in ZTABLE .If you have still any doubt regarding my question then please let me know.

Abhishek

Select query taking too much time to fetch data from pool table a005

Dear all,
I am using 2 pool table a005 and a006 in my program. I am using select query to fetch data from these table. i.e. example is mentioned below.
select * from a005 into table t_a005 for all entries in it_itab
                   where vkorg in s_vkorg
                   and     matnr in s_matnr
                   and     aplp   in s_aplp
                   and     kmunh = it_itab-kmunh.
here i can't create index also as tables are pool table...If there is any solutions , than please help me for same..
Thanks ,

it would be helpful to know what other fields are in the internal table you are using for the FOR ALL ENTRIES.
In general, you should code the order of your fields in the select in the same order as they appear in the database. If you do not have the top key field, then the entire database is read. If it's large then it's going to take a lot of time. The more key fields from the beginning of the structure that you can supply at faster the retrieval.

How to fetch data from different sources into one source (like into Ztable)

hi friends,
As per our client requirements they want to develope an Inventory and an Ontime delivery report in BO on top of Oracle database.
Situation is some thing like they have ECC 6.0.and they want to collect all inventory and ontime delivery data at one place.According to me that could be one Ztable in which we can gather all data.Apart from that they are going to use Data Integrator in which they can directly fetch the data from R/3 system(They dont want to have BI system) and put all data in Oracle DB.On top of ORacle BO person can develop BO reports.
My question is how to fetch all data at one place and what are the tables going to be use.
kindly help me out as its very important project.
Thanks
Abhishek

The following is my standard reply to those who need to get old data from a backup in one account and add it to another account. The method described here may be applied to your case. It would be a bit of a long process, though.
When connected to the account you want to GET data from, Go to Settings>iCloud and turn all data that is syncing with iCloud (contacts, calendars, etc.) to Off.
When prompted choose to keep the data on the iPhone.
After everything is turned off, scroll to the bottom and tap Delete Account. Next, set up a new iCloud account using a different Apple ID and turn iCloud data syncing for contacts, etc. back to On. When prompted, choose Merge. This will upload the data to this new account.
Note that this only affects the "Apple data" like contacts, calendars, reminders, etc. Many third party apps also use iCloud to store data files there. These files may be lost in the process, unless the apps also keep the data locally on the device.
NOTE: Photos in the photo stream (if you use it) will not transfer to the new account. It is advised that you save the photos to a computer before performing the account switch.

Doubt in Fetching data from a View

Hi all,
I want a data from a view v_tvko.How to use a view in program for fetching data from that.
Please help.
Thanks in advance.
Nithin.

Hi Nitin,
We can't directly refer a view to get data.
We need to refer the tables using which a view has been created.
Using those tables, we can fetch the data as per our requirement.
For suppose, if you go to a view in SE11, then click on Tables tab, there you can get the reference tables.Then you need to check for the fileld in those tables for which you require the data.
Post the query directly on the table instead of view.
Hope this will help you.

Anand.

Do we need to configure something before loading data from a flat file from OWB Client?
Any help would higly appreciable.

BAM reports taking more time while fetching data from EDS

Select query taking 30 sec to fetch data from table containing BLOB column.

Hi Friends,<o:p></o:p>
Please help me...<o:p></o:p>
I have 15 columns in a table, in that 2 columns containing blob (images).<o:p></o:p>
More than 22 lakhs records are in a table.<o:p></o:p>
While i am try to fetch data from this table it nearly takes 25~30 sec to execute that query.<o:p></o:p>
When i deleted the two columns containing blob and i tried its executing fast .<o:p></o:p>
I should not change the table schema.<o:p></o:p>
Views also i created and indexes also there in a table.<o:p></o:p>
How can i improve the query execution speed?.<o:p></o:p>

And how large is the size of BLOB data in your table? If it's several giga bytes, then the time is simply required to read the amount of data from disk and to transfer it to the Client.

Eliminate duplicate while fetching data from source

Hi All,
CUSTOMER TRANSACTION
CUST_LOC     CUT_ID          TRANSACTION_DATE     TRANSACTION_TYPE
100          12345          01-jan-2009          CREDIT
100          23456          15-jan-2000          CREDIT
100          12345          01-jan-2010          DEBIT
100          12345          01-jan-2000          DEBITNow as per my requirement, i need to fetch data from CISTOMER_TRANSACTION table for those customer which has transaction in last 10 years. In my above data, customer 12345 has transaction in last 10 years, whereas for customer 23456, does not have transaction in last 10 years so will eliminate it.
Now, CUSTOMER_TRANSACTION table has approximately 100 million records. So, we are fectching data in batches. Batching is divided into months. Total 120 months. Below is my query.
select *
FROM CUSTOMER_TRANSACTION CT left outer join
(select distinct CUST_LOC, CUT_ID FROM CUSTOMER_TRANSACTION WHERE TRANSACTION_DATE >= ADD_MONTHS(SYSDATE, -120) and TRANSACTION_DATE < ADD_MONTHS(SYSDATE, -119) CUST
on CT.CUST_LOC = CUST.CUST_LOC and CT.CUT_ID = CUST.CUT_IDThru shell script, months number will change. -120:-119, -119:-118 ....., -1:-0.
Now the problem is duplication of records.
while fetching data for jan-2009, it will get cust_id 12345 and will fetch all 3 records and load it into target.
while fetching data for jan-2010, it will get cust_id 12345 and will fetch all 3 records and load in into target.
So instead of having only 3 records, for customer 12345 it will be having 6 records. Can someone help me on how can i eliminate duplicate records from getting in.
As of now i have 2 ways in mind.
1. Fetch all records at once. Which is impossible as it will give space issue.
2. After each batch, run a procedure which will delete duplicate records based on cust_loc, cut_id and transaction_date. But again it will have performance problem.
I want to eliminate it while fetching data from source.

You can do it this way....
SELECT DISTINCT cust_doc,
                cut_id
FROM customer_transaction
WHERE transaction_date >= ADD_MONTHS(SYSDATE, -120)
   AND transaction_date < ADD_MONTHS(SYSDATE, -119)However please note that - if want to get the transaction in a month like what you said earlier jan-2009 and jan-2010 and so on... you might need to use TRUNC...
Your date comparison could be like this... In this example I am checking if the transaction date is in the month of jan-2009
AND transaction_date BETWEEN ADD_MONTHS(TRUNC(SYSDATE,'MONTH'), -27) AND LAST_DAY(ADD_MONTHS(TRUNC(SYSDATE,'MONTH'), -27)) Your modified SQL...
SELECT *
FROM customer_transaction
WHERE transaction_date BETWEEN ADD_MONTHS(TRUNC(SYSDATE,'MONTH'), -27) AND LAST_DAY(ADD_MONTHS(TRUNC(SYSDATE,'MONTH'), -27))Testing..
--Sample Data
CREATE TABLE customer_transaction (
cust_loc number,
cut_id number,
transaction_date date,
transaction_type varchar2(20)
INSERT INTO customer_transaction VALUES (100,12345,TO_DATE('01-JAN-2009','dd-MON-yyyy'),'CREDIT');
INSERT INTO customer_transaction VALUES (100,23456,TO_DATE('15-JAN-2000','dd-MON-yyyy'),'CREDIT');
INSERT INTO customer_transaction VALUES (100,12345,TO_DATE('01-JAN-2010','dd-MON-yyyy'),'DEBIT');
INSERT INTO customer_transaction VALUES (100,12345,TO_DATE('01-JAN-2000','dd-MON-yyyy'),'DEBIT');
--To have three records in the month of jan-2009
UPDATE customer_transaction
   SET transaction_date = TO_DATE('02-JAN-2009','dd-MON-yyyy')
WHERE cut_id = 12345
   AND transaction_date = TO_DATE('01-JAN-2010','dd-MON-yyyy');
UPDATE customer_transaction
   SET transaction_date = TO_DATE('03-JAN-2009','dd-MON-yyyy')
WHERE cut_id = 12345
   AND transaction_date = TO_DATE('01-JAN-2000','dd-MON-yyyy');
commit;
--End of sample data
SELECT *
FROM customer_transaction
WHERE transaction_date BETWEEN ADD_MONTHS(TRUNC(SYSDATE,'MONTH'), -27) AND LAST_DAY(ADD_MONTHS(TRUNC(SYSDATE,'MONTH'), -27));Results....
CUST_LOC     CUT_ID TRANSACTI TRANSACTION_TYPE
      100      12345 01-JAN-09 CREDIT
      100      12345 02-JAN-09 DEBIT
      100      12345 03-JAN-09 DEBITAs you can see, there are only 3 records for 12345
