This application creates electronic invoices based on SAP Business ByDesign Custormer Invoice Documents. When invoked, it pulls the data from ByD OData services, based on the message data, and calls the Tax Authority web service (in this case AFIP) to issue the electronic invoice. Once it is authorized and created, the solution writes back the signature data into the ByD Customer Invoice extension field. We adopted the SAP Business Technology Platform Enterprise Messaging as the default message broker service and SAP Business ByDesign as the core ERP.

• SAP Business Technology Platform Enterprise Messaging
• Credentials to access AFIP web services
• SAP Business ByDesign Tenant
• A ByD Custom Odata Service for Customer Invoice

• you must create a new extension field on customer invoice document, and add it to the OData service exposed above
• Although we took AFIP as the provider to issue the Electronic Invoice for this prototype, you can adapt the code to consume the Tax Authority web services you need.

• AFIP_TOKEN: your token provided by AFIP;
• AFIP_SIGN: your sign provided by AFIP;
• AFIP_CUIT: your company's Unique Tax Identification Code.

cf set-env <app_name> ERP_URL <your_ERP_URL>
