LO EXTRACTION

39 Views

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>
