How do we Assign Ledger to Legal Entity

Hello Team,

While making a setups of e-Business Tax i have checked  Use Subscription of the Legal Entity box in the Operating Unit party tax profile  Navigation Parties => Operating unit owing Tax content. After doing this setup i am not able to select the Ledger in while creating Tax.

The metalink note 551561.1

specifies that you need to assign Ledger to Legal Entiry.

Can any one let me know how do we assign exisiting ledger to Existing legal Entiry.

Thanks in Advance
