EB Tax set ups

I am setting up EB Tax for China in R12:

I followed these steps:

Setup eB-Tax: Define Tax regimes          

Setup eB-Tax: Defaults and Controls     

Setup eB-Tax: Define Taxes      

Setup eB-Tax: Define Tax Status             

Setup eB-Tax: Define Tax Jurisdictions 

Setup eB-Tax: Define Tax Recovery Rates

Setup eB-Tax: Define Tax Rates

Setup eB-Tax: Define Tax Rules (Defaults)          

When I try to check the box  Make Tax Available for Transactions , all these errors appear:

  

1. Define either a   default tax status or a tax rule for the rule type: Determine Tax Status.

    

2. Define either a   default tax formula or a tax rule for the rule type: Determine Taxable Basis.
