2727203 - Rename a functional index using sp_rename - ASE

Would like to know if calculated index/column/functional index can be renamed.

Following command fails:

• sp_rename "tablename.sybfi6_1" sybfi4_1
  go

Msg 17786, Level 16, State 1:
Server 'svr_name', Procedure 'sp_rename', Line 278:
Object name cannot be changed either because it does not exist in this database,
or you don't own it, or it is a system name.
(return status = 1)

• sp_rename "tablename.sybfi6_1", sybfi4_1, "index"
  go

Msg 17782, Level 16, State 1:
Server 'svr_name', Procedure 'sp_rename', Line 468:
You do not own a table, column or index of that name in the current database.
(return status = 1)
