Tax breakup and lines not see on transaction form - R12.1.3. IL

Hi,

After attaching the taxes on the sale order - india form and booked the sales order and done other steps. Then ran the India India - Local Concurrent For Processing Order Lines to AR and then the autinvoice master program for a sale order.

The invoice got interfaced but when queried on the global transaction form, the tax lines (using the tax button) and tax amount (balance due  header block) is not seen on the form. Only the item value is seen. Why is the taxes amount not appearing on the invoice.

Please advise

Thanks
