How to setup price list at ledger level?

Hi,

I have several ledger, one of them has 2 operating unit.

I use 1 price list for both operating unit. Our user won't enter price list for each operating unit.

But if we use global in price list, other ledger can see this ledger price list.

Is there any other setup that we can use for other ledger cannot see this ledger price list and we shouldn't enter price list for each operating unit?

Regards,

Armi
