Add field in AR_INVOICE_API_PUB.create_single_invoice API

Hi All,

I am creating a invoice using AR_Invoice_api_pub.create_sibgle_invoice successfully, I also need to store old_trx_number in ra_customer_trx_all table, but once I am passing this value in header section of API, it is showing message old_trx_number must be declare, could you please let me know how can we declare the old_trx_number and fix this issue.

Below is the header section of API

p_trx_header_tbl(l_cnt).trx_header_id := l_cnt;

p_trx_header_tbl(l_cnt).old_trx_number := '619578'; --head_rec.thourref;
