Hi Kenneth,
the Checkbox Setting is only required if you want to extract data into another system from your object.
To find your generated Export datasource you have to Switch to the Datasource tree in RSA1.
Click through the InfoAreas: 0BW_DATASOURCES - DM - DM-IO and do a right click there "Replicate Metadata" ... then you will get a pop-up window, asking you what to do.
You chose:
- active versions
- Create BW Datasources
- no deletion of BW Datasources
- reactivation in Background (no Transport Connection)
Then a list appears and you look for the one you want to create, de-select all others... and "OK".
Voila, it will be created, and you can find it as "8<yourIOname>
BR, Martin
