Hi,

We use function module for generic extraction when our data is comming from different source tables based on complex logic.

The easiest way to work out with Function Module is to copy the standard one and modify according to your reqirement.

The standard one is RSAX_BIW_GET_DATA_SIMPLE .

Dont forget to copy the Function grp RSAX into a custom defined Grp and Modify the Ranges options as per ur req.

and in Function module, in Sourcecode and Tables, Do modify the E_T_data with ur Generic datasource ,make sure u also modify the select statements within the sourcecode. If you have an idea on ABAP its really easy to work out.

check this link for sample code:

And regarding the creation of Datasource:

- Goto RSO2

- choose what kind of datasource u r creating and a name

- Choose the approriate app. comp. under which you want to create the generic datsource

- Click on Extraction by FM

- Give the function module name

-Then you can save and select the fields required (with generic delta capabilities).

- check in rsa3 to make sure it can extract data (after activating the datasource)
