How to integrate EB Tax to AR .........

Hi Gurus,

I'm using EBS R12.1.3 and did setup for EB Tax in it, every thing looks good.

Now when I created AR invoice line, system is not automatically creating tax line for it, however I'm able to create manually tax line, and it's calculating tax correctly.

So, looks like some integration point between EB Tax and AR is missing. please advise about it.

I would greatly appreciate for your help.

Thanks,

Sanjeev
