Can anyone explain how the LO data source flows from ECC to BI up to cubes?

Question

Dear all,
Can anyone explain step by step (HOW THE DATA FLOWS)....By taking 2LIS_11_VAHDR  from SD , starting from Activate Data source in ECC  to Info Cube in BI7.0. Please this will be helpful -
Thanks for the advance answers...

Hi Harish,
First go to RSA5 in ECC  select your datasource 2LIS_11_VAHDR and activate it.
After activatin check in RSA6 whether the datasoure activated properly or not.
Then log on  to BI sytem Select datasource and click on replicate.
Then Create Infocube infopackage ,Transformation, DTP ...entire flow. But dont schedule it because there is no data in SETUP Tables.For full load first we need to run statistical set up , so that data should come to SETUP Table.
Now go to ECC  enter T.CODE OLI7BW to filled up the SETUP Table  for datasource 2LIS_11_VAHDR.
It will ask  you for Run Name etc give the run name and time limit and execute it.
If you get some error then first delete the SETUP Table by using Transaction Code LBWG.
In LBWG it will ask you for applicatiion number , give 11 i.e for sales datasourc and execute it.
Data will get deleted from SETUP Table. To check data is deleted or not  in SET UP Tabe go to database table MC11VA0HDRSETUP. Always remember the name of SETUP Table will be Extract Structure followed by SETUP.
EX : If extract structure name is MC11VA0HDR then name of the SETUP Table will MC11VA0HDRSETUP.
If data gets deleted then again go to 0LI7BW and run the Statistical Setup then agan check in MC1VAOHDRSETUP table contains data or not.
Then trigger the Infopackage and DTP in BI.  Above steps was for full load.
Now to Load deltas follow below steps.
First Create INIT at BI side which enable delta at ECC Side.
Then go to ECC and execute T.CODE LBWE.
LBWE is LO Cockpit Work Bench. There we have folowng functions 1.Maintan Datasource. 2.Maintain Extract Structure. 3. Job  Control.  4.Delta Type 5.. Activate/deactivate.
If you want to add any new field to your datasource then to to Maintain Extract Strucutere remeber before adding or modififying datasource first we should deactivate datasource by using 5th function  Activate/Deactivate.
Then select DELTA TYPE in delta type we have four types of delta. 1. Delta Queue (RSA7) 2. Queued Delta (LBWQ)
3. Unserialized (SM13) , 4. Seriaized (SM13)
If you select Delta queue then deltas drectly come to RSAT.
if you select Queued Delta  deltas goes to LBWQ then you have perform V3 job by using Job Control  function to move data from LBWQ to RSA7. Remeber to BI  data  always goes from RSA7 only.
If you select Unserealized then delta goes to SM13 again you have to perorm V3 Job to move deltas in RSA7.
Serialize update is not in used in Lo-cockpit.
There is a differerence between  DELTA QUEUE , QUEUED DELTA, UNSERIALIZE UPDATE. Pls find the differences on net.
Then select your delta type and create deltas dtp in BI and start loading .
Hope this help you.
In RSA7 we have two tables delta and repeat delta, to know the functionality of this please search for the documents on  net.
