AGIS Tax in AP is not defaulting from AR transactions - (Taxware involved for AR alone)

Hi,

We are using 'Taxware'  for AR alone .   For AP,  EBTax is used.

We are creating AGIS transaction and importing the AR Invoice.    The taxes are calculated correctly from Taxware.

However,  when we import the AP invoice,  the taxes in AR are not defaulting in AP invoices.

We ensured that both the operating units are subscribed to the  regimes.

Can you please help/

thanks in advance,

R.Kumar.
