Hi Tansu,
that's a good list.
1) True. Typically the data is present in a DSO as well (before you move it to the InfoCube on BWA). Running the query of the DSO is then a relatively quick solution.
2) Yes, but you can create snapshots with BW on HANA as well.
3) Yes, but you can use Explorer on top of BW on HANA models as well.
4) No. The setting works as is for both BWA and HANA.
#1 is included in my Checklist Tool (SAP Note 1729988).
