Conversion of the invoices in Receivables
I need to convert invoices processed in legacy system during the upgrade to R12 downtime and I am using api(s) such as ar_invoice_api_pub.create_single_invoice etc.. but user wants to get already posted transactions as it was in legacy with the same GL posted date etc. How is it possible using api(s) ? or we still need to create accounting in R12 and transfer to GL as usual?
