"The error I got is
With the Partitioning, OLAP and Data Mining options
ORA-39001: invalid argument value
ORA-39071: Value for EXCLUDE is badly formed.
ORA-00920: invalid relational operator"
this Error you get because you can not use the wrong syntax for Exclude in your command
I tried your suggestion but it only exclude the grants provided the grantor not the grantee.
AFAIK , you can not do what you want.
