3454693 - No real time revenue recognition triggered for posting to customer project

When posting expense to customer project WBS element XX.1.X, there's no revenue recognition triggered accordingly.

SAP S/4HANA Cloud

Possible reason could be that the work package XX.1.X is not mapped to any billing element XX.0.X.

Kindly check in APP 'Plan Customer Projects', check the 'Work Package' tab, find the relevant description of XX.0.1,
then check in 'Billing' tab to see whether this work package/description is assigned to a billing element, which used for revenue recognition with revenue recognition key.
If not, kindly assign it accordingly and repost the posting and see if the real time postings could be triggered successfully.
