How Delta Queue fetches data in source system.

Hello Experts,
SMQ1 is physical storage of all transactions created in the source system. Delta Queue(RSA7) fetches data from SMQ1. In case of Queued and Unserilized V3 delta where LBWQ and SM13 come into picture. Can you please clarify my doubt.
Thanks in advance.

Hi,
it works in the same way as before in case you are not using the new features like the dtp and the transformations. Using the new features, you schedule a infopackage to load the data up to psa and schedule a dtp to post the data to the targets.

No data in source system

Hi at all,
I extrakted initial data from source system and get a warning "No data in source system". I checked the system and it is ok. Plz help me

Hi
Yep ,,, if u do and delta after Init ...the records it will fetch is 0records
IF there are no changes happend in r3 then u wont get the data ..
So, Go to the R3
1) check ur delta queue in R3
2) or RSA3 and test extract for ur datasource in the D mode and also select ur sourcesystem as the BW sstem
u have to get 0 records
hope it helps

Error in Process Chain while extracting data from source system

Hi All,
Dail we are facing problem while retrieving the data from source system for the data source 0TB_AMOUNT1 in the process chain, it is giving error "Function module BANK_TMC_API_SIM_GET does not exist Furnction module". when I repeat the step than it is going fine.
Please let me know why this error is coming for first why it is not coming after repeating the step?
Thanks & Regards,
Murali.

Hi Murali,
Hope you are doing good..
Is it a full or Delta load on a daily basis? Did you check if the FM exists in your system?
Did you try debugging the load in source system and check if the extractor is trying to call FM you mention.
If possible please post the exact error message you are receiving so that we could get an idea whats the error and why you are encountering it.
As of now what i can suggest is, go to RSA2 in source system, give the datasource name and check if the extractor code has FM in it.

Logical System name in RSA7 Delta Queue wrong because of BW System Change

Hello All,
we changed our BW System landscape. Before we had one BW development system (System ID: DBW) and now we are using BW development system (System ID: EBW).
Now we face the problem, that in our R/3 system in the delta queue the wrong / old development system is written (DBWCLNT100), but instead of this there should be EBWCLNT200.
Has anyone of you got a clue where we can change this?

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

once you create the archiving object on any cube by defaulty the info package maintain the one option
Load from archive data( There select with which archived file you required).
2) Create infostructure,
create the datasource and reload it to infocube

I would be very thank ful if any body cuold suggest me with a link on the notes ar step by step formatt.
Point's will be awarded,Thanks in advance.

Hi Jay,
From Delta queue(RSA7) ur BW system is going to fetch the records of R3 or source system.
After extraction process it reaches RSA7 from there when u triggers infopackage
the job is ready to flood ur D.target with records.
Ensure that records are there for corresponding D.source this has to be attained thro' various Update methods(v3).
DataSource that is generated in SAP BW on the basis of a file-DataSource and
that can be used to push data to SAP BW
for more info on creation of XML D.source refer the link

How to Create an R/3 source system and load data from there

Hello All,
Till now I have only worked with Flat files. I want to create an R/3 source system and extract data from there on to my Info Providers.
Does anyone has detailed steps for that. I am using BW 3.5 system
Thanks n Regards,
Abhishek

1. Type Transaction WE30. Check iDoc types
2. Type Transaction SM59. Maintain RFC destinations
a.) Open the RFC Destinations. b.) Find your Source System and double click on it. c.) Technical setting should contain information regarding yoursource system d.) Logon Information should contain source system client and name & password for you remote logon. We use RFC_SAB for BW logon to R/3 and RFC_AAE for R/3 logon to BW. Password for both is always xxxxxxx. e.) Execute your 'Test Connection' & 'Remote Logon'. You should NOT be prompted for a password, if you are then the logon info is incorrect. f.) Repeat above to verify RFCs for other systems (CRM etc)
3. Type Transaction WE21. iDoc Processing Ports.
a.) Select 'Ports' and then 'Transactional RFC'. b.) Click on the Port # for you source system. c.) Verify description & SAP R/3 version.(BW 2.1C should be release 4.x) d.) RFC Destination should be one created in SM59. If non-existent then create one
4. Type Transaction SE16. Data browser (for R/3  BW Connections)
5. Type Transaction SM30. Msg Types & Assignment to iDocs
Enter 'EDIMSG' in the Table/View field. Click on the 'Enter Conditions' option for Restrict Data Range. Click 'Maintain'. Select Message Type. Then enter 'RSSEND' in "From' field. Verify that the Basic Type matches what is in your RSBASIDOCtable for each of your connections. If any are missing any entries you must create them as follows: Create another session and type Transaction WE30. Enter IDoc Type (ZSBAXXX) in Obj. Name field (Suggestion: Start new type with 'ZS' + Transfer Structure Prefix + (3)#'s) Select Create. Select "Create from Copy'. Enter 'RSSEND" in 'Copy From' field Enter Description (i.e. IDoc Type for BW Development) Execute (Green Check). Repeat for other missingentries.
6. Go to the SM30 main screen. Clients Overview
Enter 'T000' in the Table/View field. Click 'Maintain'. Verify correct Client and Description. If incorrect enter.
8. On BW Type Transaction WE20. Partner Profiles
9. On R/3 Type Transaction WE20. Partner Profiles
10. Check all is correct

How to create DataSource for BI Source System in RSA1?

I have a BI Source System defined, however I can't figure out a way to create a new DataSource for it. I can create DataSource objects for all my other Source Systems, but I can't figure out how to do this for this BI system.
I select my BI Source System, right-click, choose "Display DataSource tree". When I right-click from the DataSource tree, I expect to get "Create Application Component" and "Create DataSource" options, but instead I only see "Replicate Tree Metadata" and "Replicate DataSources" options.
How can I create DataSource objects for my BI system?

Hi,
I guess you want to create a custom developed source in BI itself. For that you need to create the data source in RSO2 and inside you need to give the specific aplication component under which you want this DS to be in. Generate a data souce and then go to BI My self Source system and then replicate that particular appl component o view your data source.
Hope this helps
