Inbound Interface for Outgoing Invoices (FB70) in S/4HANA Cloud

[Expert]

We only use the finance module of S/4HANA Cloud, no SD module. Therefore, we will use the App FB70 - "Create Outgoing Invoices" to post customer invoices.

We will also get outgoing invoices from a third-party system. So we are searching for a suitable API to transfer the outgoing invoices from the third-party system to S/4HANA Cloud. We identify the API "Journal Entry - Post (Asynchronous)". This API provide a node "DebtorItem" for line items on a customer account. When I interpret the API definition correclty then we could create an customer invoice via this API, correct? It is important for us that the posting via the Journal Entry API also allow to do the dunning process for the created outgoing invoices.

Please can you give us feedback if the "Journal Entry - Post" API fulfill our requirements or if you could recommend a different API for our needs. Please consider that we need a solution in the finance module because we don't use SD.

Hi, can you confirm it's possible to create a customer invoice (FI invoice) with the proposed API?

As a rule of thumb you can safely assume, once a posting has been saved successfully in S/4HANA Cloud, it is subject to the same governance and procedures as any other such posting. Now, specifically for customer invoices posted via APIs (such as the one you identified) they should be processed with dunning in exactly the same way as all other manually created customer invoices. Unless of course you configured specific differences for such postings from APIs/3rd party systems. You may want to establish test procedures that hone in on asserting exactly this quality: Do API-posted documents behave the same way in dunning as manually posted ones when they should?
Please let me know if you need any further support wit this.
