2110032 - DBCC UPGRADE_OBJECT not recognizing compiled objects after upgrade - SAP ASE 15.7

• The database has just been upgraded from version 12.5.4 to version 15.7 .
• The "dbcc upgrade_object (dbname)" command reports:

DBCC upgrade_object: Command found no compiled objects in database 'dbname'.  

• However "sysobjects" shows there are hundreds of compiled objects such as stored procedures, views and defaults in that database.
• The "dbcc upgrade_object (dbname, objectname)" command for known compiled objects also cannot find them:

1> dbcc upgrade_object (dbname, objectname)
2> go
DBCC upgrade_object: Object objectname does not exist in database dbname
  
1> dbcc upgrade_object (dbname, objectname, force)
2> go
DBCC upgrade_object: Object objectname does not exist in database dbname
