Hi Matthias
Based on IBM's documentation (https://www.ibm.com/docs/en/app-connect/13.0.x?topic=enterpriseone-outbound-processing-jd-edwards), it appears the adapter only supports synchronous outbound request processing. It processes requests using either business functions or XML Lists, and returns a response once the operation is completed.
As for calling a UBE (Universal Batch Engine) asynchronously, this doesn't appear to be supported out of the box through the standard adapter capabilities. The adapter primarily interacts with JD Edwards EnterpriseOne by invoking business functions or retrieving data via XML Lists, and all interactions are handled synchronously.
If asynchronous UBE execution is a requirement, an alternative might be to trigger the UBE via a business function or custom API that allows for decoupled processing. This would likely require some additional setup in JD Edwards and needs to be validated in practice.
Hope this helps.
