tax rate has been input into rate at invoice receivables but cannot calculate tax because tax code n

Hi All,

I am newly setup for e-business tax.

i need someone to give advice or document that i need to learn step by step to do the tax.

Condition :

Migrate data from 11 and reimplement to 12.

What i have done for my setup :

now i am using 12.1.3 and setup for new regime, tax, status, jurisdiction, rule, etc..

and running geography hierarchy and running geography reference and  the output show that location is not created.please contact your system administrator.

i create invice and fill detail item and description at invoice lines and fill tax rate from list of value.

after that i save transaction and the invoice cannot calculate the tax amount.
