PANNOTAVBL-AP Invoice Validation Error

Hi,

Step1) I entered PANNOTAVBL on Supplier Additional Form.

2) I have created Stand alone AP Invoice

3)At the time of Validation i am getting Error."Invoice Validation is Throwing the Error "Invalid Pan, Deduction At Higher Rate Is Not Selected"

Can you please help me,What are the steps do i need to follow 20% TDS?

Do i need to Define Tax Code for also 20%?

What is the Default TAX Code do i need to attach at Supplier Leve?

Thanks,

Hari.
