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 Roberto,

I went through your document but i could not find any thing related to keyword datasource. but good one to understand other concepts..

What i understood here is there is fn called

1. MCEX_UPDATE_CALL_XX which gets executed when the document is posted and data comes in extract structure

2. Using MCEX_UPDATE_XX_QRFC data comes to BW delta queue.

Can you explain more ..

Sachin,

everything inside the weblog is related to your keyword datasource !!!

What do you understand about datasource concept ?

Datasource (as physical object) is nothing is you don't link it (and consider during your reasoning) together with its extract structure and extraction pgm/mechanism: it would be only an empty box !

So, after the two points that you highlighted in your previous post, add the following:

3. Start the infopackage in BW

4. The datasource, through extraction structure, will take data and everthing (as IDoc) is transferred to your BW.

If you have any doubt, let us know !

Bye,

Roberto
