Invoicing in SAP from external application

Customer orders from the operative service provision are first created as a sales order (SAP SD) for the purposes of billing in SAP. Right at the productive start-up, this makes it possible to check the data before they are released and so the activity is billed. The completeness of the data is very important, as the release process will be automated later on. The corresponding downstream processes in the SD, FI and CO modules are already triggered automatically.
