HI EVERYBODY,
I have read all the weblogs of <b>Roberto</b> regarding Lo Extraction and also the delta mechanism
After reading all that I came to an understanding how this works so I am detailing below AN EXAMPLE
<b>LO EXTRACTION WITH QUEUED DELTA METHOD
AND THE DATA FLOW OF LO to BW</b>
PLEASE KINDLY CORRECT ME IF I AM WRONG IN THE SAME ORDER I HAVE GIVEN.
Eg:--<b>SALES ORDER DOCUMENT</b> (data from here is saved to
<b>VBAK, VBAP, VBUK</b> , etc ( these are application table and from here data is written to
<b>MCVBAK, MCVBAP, MCVBUK</b>, etc ( these are the LIS comm struc linked to extract structure.)
<b>EXTRACT STRUCTURE</b> ( Here we maintain the extract structure by inactivating it after maintaining
Is finished we activate it .)
<b>NOW COMES TO DELTA MANAGEMENT</b>
Here we can specify the update type in <b>UPDATE MODE</b> ( For example <b>QUEUED DELTA</b>) and when we
Specify the delta method the data from extract structure moves to
<b>EXTRACTION QUEUE (LBWQ)</b>
By using <b>JOB CONTROL</b> we do the collective update run immly r else can be scheduled for An after date to transfer data from <b>EXTRACTION QUEUE TO DELTA QUEUE (RSA7)</b>
<b>DATA SOURCE.</b> (Generate data source)
In BW we have to create a info package and in the update tab we give delta update (this is in assumption that already I have done delta initialization load before.)
I THINK THIS THE PROCESS OF EXTRACTING DATA FROM LO AND THIS IS HOW DATA FLOWS TO BW FROM DIFFERENT STAGES.
KINDLY CORRECT ME IN THE SAME SEQUENCE THANKS A LOT FOR ALL THE INPUTS
SPECIAL THANKS TO <b>ROBERTO</b> FOR BEING A VERY GOOD GUIDE.
THANKS AND REGARDS
NEELKAMAL<b></b>
