>> "E:\BACKUPS\CLONEBKUP\DB03HSMQIF_1_1
Is this drive shared/mapped?
this should look like a local drive from the system where you run the duplicate.

Are you using catalog? Post your versions/

I have two machines Source and Destination. On source machine i have instance e.g. A on E:\ and i want to clone it to instance B on destination machine on differnt drive or by using drive mappings bec i have only one drive on Destination and i dont want to create another one.
E:
\BACKUPS\CLONEBKUP\DB03HSMQIF_1_1 is not shared and is on source system and then same directory structure on different drive on destination

i m running duplicate on source machine like

duplicate_instance [source_instance_name] [destination_instance_tns] [instance_home]

Look into the documentation.
the basic concept is
if your RMAN backup is residing in \BACKUPS\CLONEBKUP\DB03HSMQIF_1_1 (on source) and you want RMAN to use these backupset and clone the database to another host (target) then, the backupsets should visible from the target host.
So, you need to share the /backups across the machines.
Run your duplicate from the target machine.
The directory structure need not be the same in target.
Please refer oracle rman documentation.
Everything is explained in detail.
