SAP GoldenTax Interface Research and Tax Error Correction Algorithm Design
Abstract: SAP golden interface focus on company which use the SAP and VAT invoicing system, realize the integration of the two systems in enterprises and in reducing sales invoice data manual migration between the two systems of repeated work and unsafe factors at the same time, meet the needs of enterprise multiple clients making out an invoice at the same time remotely. This topic adopts the model of the component interface. The interface system get interaction with SAP by RFC interface pattern, and use developing tool which SAP is adopted for .NET platform called Nco connector. The connection with the GoldenTax system use the component patterns which provided by GoldenTax, remote data transmission using the SOAP protocol. To the difficulties of this topic is mainly Focused on the SAP parameter configuration, and the secondary development of the interface components. Interface system currently implemented SAP invoice information access and correct the invoice data remote transmission, subject has been basically achieved expected.
