BW transport

Hi,
We are implementing ECC 6.0 and SCM 5.0 APO in UK/I client.
Because of cross

client strategy, i need to transport planning area and planning book to the default client.
when i try to transport it,

system gives me error called ' the typa/ BIO/9A0IVWKNDGD/ is unknown'.
if anybody can explaing this and possibly

solution also for this??

Thanks,
Regards,

Jignesh.
