Hi,
Once you displayed the data at RSA3, can you check available fields/columns.
even you can check layout also. due to the more fields, in layout those may not be visible.
Click on layout and see right side fields.
after that once again refresh your data source and save,activate all changes.
delete setup tables data and try to run data source at rsa3.
see the layout,whether it shows added fields or not.
Thanks
