EBS Tax and Taxware

Hi All,

   We are currently upgrade from 11.5.10.2 to R12. And we are currently using Taxware for our Sales Tax.

  I created a manual Invoice in R12 to see if the Tax was calculating, and the Tax got Caluculated. I was able to see the TAX on the Invoice.

  But when i did  query the  FND_PRODUCT_INSTALLATIONS where application_id = 235 (E-Business Tax),  the status is N which is Not Installed.

 My question is when we are using Taxware does E-Business Tax module need not be installed?.

Thank You,

hari.
