Customer SAP Add-on

SAP Add-on for B2b Transaction

An increasing number of companies take actions to reduce environmental footprints aiming also for cost savings Replacing traditional paper-based documents with digital e-Invoices is a huge step forward in this process, while reaching security standards within an already implemented invoicing solution can be challenging.

Within the e-Invoice product framework, Lupus Consulting introduces its native Customer e-Invoicing plugin for SAP, serving SAP-driven companies with an easy-to-setup solution to generate and handle digitally signed electronic invoices including timestamps. The solution utilizes following features:

 

  • PKI X.509-based digital signature process
  • Special file formats (PAdES for PDF documents, XAdES for XMLs and ZIPs, CAdES for general files)
  • Trusted and digital timestamping
  • GUI and customizable processes for handling files securely

How does this solution work?

The data flow consists of the following steps:

 

  1. Invoice is being posted in SAP
  2. Output program creates printout file based on the module-specific programming environment and custom processes
  3. Generated unsigned (raw) output file is being stored in central database as a new invoice message
  4. New invoice messages are collected by message handler and are being sent to e-Signature interface (either local or remote)
  5. Invoice files stored in e-Invoice dashboard get updated with the signed files, also statuses are being updated based on process outcome (success or error cases)
  6. Further Customer-specific logic is being executed
