How does the Intercompany works with India GST?

Hi,

We currently use Intercompany between our OU's and the tax is calculated using EBTax. As we are moving to GST, I have a question how we can get Intercompany invoices to work.

Our requirement is as follows -

India OU invoices Japan Entity (AR Invoice) - it should calculate India GST

Japan OU pays the invoice to India Entity (AP invoice) - it shouldn't calculate any tax

Currently with IGST, when we do an Intercompany the AR invoice is calculated with IGST - this is correct

but the AP invoice is not getting created, it is failing with the error - Unable to find the Tax Rate code.
