Hmm, I checked the other index:
SE11 says
- Index 01 OBJNM
- Index 10 DESCRIPTION (this one fails)
HANA says:
- Index 1 DESCRIPTION
I could try try removing this index 1 in HANA but better if SAP could tell us how the indexes should be named. And who knows after this one the same issue could come up for another group of tables and indexes.
