Extension of XRechnung with surcharges and discounts

The XInvoice format currently corresponds to version CII 2.2.0 of the EU standard EN 16931-1. The EDI invoices are transferred from the SAP S/4HANA merchandise management system as an IDoc (INVOIC02) to a middleware (web application developed by the customer) in a format that is standardised and prepared for all customers. The web application performs a check and transfers the IDocs via web service to another middleware, 'Lobster_data'. There, a Lobster mapping (profile) receives the IDocs, performs checks and takes care of the IDoc conversion. If there is a routing ID (reference no.) in the IDoc, the profile is called, which generates the target format XInvoice. The finished XInvoice is sent as an e-mail attachment via SMTP and processed further by the end customer. In addition to interface coordination with the e-commerce department, the technical implementation in 'Lobster_data' is one of the main areas of activity.
