Delta Concept For Data Source

[sachin_kulshrestha2]

Hi All,

!!!!!!!!!!!Make my concept clear Guys!!!!!!!!!!

Lets take a datasource 2LIS_04_P_ARBPL when any transaction is done in production planning the data is gathered in extract structure and when collective update is run (queue delta) then data comes to Bw Delta queue(RSA7). Datasource has function module which actually fetches the data when the request comes from BIW.

Query: Is the functional module which is an actual engine to datasource, and send data to BW, fetches the data from where??? Is it from delta queue or from actual tables.

Thanks

Hi Sachin!

Look here...

As you can understand, how function modules work depends from delta method you are using (direct, queued or unserialized...).

All the pictures I think can be useful to clarify the concept (anyway, during the first update - V1 - data comes from the transaction, not from the tables, directly involved only during setup job)!

Hope it helps!

Bye,
