BR0970W Database administration alert - level: WARNING, type: IN_WRONG_TABLESPACE, object: (index)

[#1]

I have a number of entries in CheckDB job for tables and indexes in wrong tablespaces. I can appreciate that these are only warning and with virtual drives probably not that important. I also know that this alert can be switched off. We are on an oracle database and I have corrected all the database errors using the following command:
alter table SAPSR3.TTREE move tablespace PSAPSR3750;

The command for the index from my old notes does not seem to be working, the command I have is:

alter index "SAPSR3.TTREE^0" rebuild tablespace PSAPSR3750;

The error I am seeing is ORA-01418: specified index does not exist. Does anyone have any idea what the command would be to move the index to the same tablespace?

Normally username and index should all have double quote, like: "SAPSR3"."Indexname" ==> but this is case sensitive Or try sapsr3.indexname
