ECC extraction from Tables to BW

Extract Structure will have all the fields available in Datasource...We can select the fields that need to be transferred to BW... This is selection is calledCustomization..Only the selected fields will be available in Transfer structure.Adding fields into the Extract Structure of Datasource is known asEnhancement..Now lets create a Datasource from an ECC table..TCODE - RSO2

As VBAK is sales table.... select application component as SD

Now save..

This is the Extract structure of our Datasource...we have 4 columns here..SelectionHide fieldInversionField onlySelection: This gives Selection option for that field. which will help in selective loading of data for that field...

lets keep Sales document, Sales organization and date as selective loading fields..

Hide field: The fields checked here will not be available in Transfer structure..all the fileds which are not needed is checked....

After doing the needed customization.. generate Datasource

Now our Datasource is ready... now lets check if we have data in that Datasource using Extract checker

Tcode RSA3

we got Sales organization, sales document and date for selective loading...( It is because we had given check mark in selection column)

Now replicate Datasource in BW..

The datasource what we made in ECC is now replicated in BW..

Replicated Datasources will be inactive mode... activate datasource..

Create an infoPackage and pull data..

Now we have data in PSA ..

Take it to the corresponding targets...
