Err Mssg from AR API:Location tax type is not allowed.

 Hi

We are using AR API to Create AR Invoice based on Delivery

AR_INVOICE_API_PUB.create_invoice(p_api_version => 1.0,
                                  p_commit => 'T',
                                  p_batch_source_rec => l_batch_source_rec,
                                  p_trx_header_tbl => l_trx_header_tbl,
                                  p_trx_lines_tbl => l_trx_lines_tbl,
                                  p_trx_dist_tbl => l_trx_dist_tbl,
                                  p_trx_salescredits_tbl => l_trx_salescredits_tbl,
                                  x_return_status => l_return_status,
                                  x_msg_count => l_msg_count,
                                  x_msg_data => l_msg_data);

we are passing TAX CODE as LOCATION  and tax rate is null . Invoice is not created we are getting message
