Fullfilled Order Form - excise duty amount not showing R12.1.3

Hi,

After ship confirm and running the india - excise invoice generation program prior to Auto invoicing. When the sales order with delivery id is queried on the fullfilled order form, the tax amounts for excise related tax lines is showing zero. This is happening with trading organization. This is on R12.1.3.

Therefore we are facing with the below problem:

1) AR invoice creation competed without ED

2)  Invoices is updated in the customer ledger, but without ED value.

3)  Similarly, we are not able to print the dealer invoice.

Please advise how to resolve.

Thanks
