Tax rate is not getting applied on project invoice lines based on the tax code

  Hi,

I am using R12 application and here is my question.

On the project invoice lines, i am changing the tax classification code followed by the action of approve and release before interfacing the Invoice lines to AR. After this, when I interface the invoice and run the tieback process, the changed tax classification code is reflecting but without the applicable tax rate of the new tax code. The tax code and the % is misleading in the system. The system, by default, picks up the one particular standard rate irrespective of the changed tax codes and we are not sure from where it is getting reflected.
