Hello,
can you check if you added the package privileges for the "designstudio" package to your user?
You add the designstudio package in the user (or role) profile under Package Privileges and then you give the following rights:
REPO.READ
REPO.READ_IMPORTED_OBJECTS
REPO.ACTIVATE_IMPORTED_OBJECTS
REPO.MAINTAIN_IMPORTED_PACKAGES
This fixed the problem for me without adding the xs privileges (and btw this is specified in the DS1.5 on HANA user guide).
Hope that it helps
