Hi Laurent,
You should validate a target database.
Validation utility (dbvalid)
http://dcx.sap.com/index.html#sa160/en/dbadmin/dbvalid.html
When you receive the same error(Assertion failed: 106901), it's necessary fort to rebuild the database.
BTW
Can you confirm the following SAP note?
2216888 - A subselect with LIST or COUNT and GROUP BY of only constants fail
This problem should be fixed with version 16.0.0.2174.
However, your version(16.0.0.2213) is fixed.
When this problem is not resolved even if you rebuild the database, I doubt new problem.
Thanks,
Atsushi
