Hi Patrick,
Recently I realized that things changed when schema mapping.
Initialy it was used to "rename" the authoring schema to desired target schema on the import moment only.
Currently (tested on rev53) it doesn't rename so inside XML model you find the original authoring schema, even after an export/import.
I found no mention to this change, but the hana_dev_en.pdf points to this as normal behavior.
In order to have our schemas in proper order we exported all models in developer mode, changed schemas inside XML (with text editor) and imported it back to HANA.
About the analytic view you can found the blank answer. Read item 7.1.6
