Hi Amir,
I think it is possible to create a view on top of the granular DSO. However, you will have to delete the original DSO (/BIC/AOXXX00) in order to reuse the same name. Creating a view (using t/code SE11) with the same name as the original DSO (/BIC/AOXXX00) gives an error message. This is not a surprise since the same tables are used (e.g. DD02L).
Best regards,
Sander
