Symptom
When running settlement with app "Run Settlement - Actuals", the error "Account XXXXXX requires an account assignment relevant to cost accounting" is triggered for the Cost Elements defined in the distribution rules, even though the sender is a Project.
Environment
SAP S/4HANA Cloud Public Edition
Cause
This happens due to a missing assignment, since project is the source of the settlement, and it's not relevant with the settlement cost element.
Resolution
In order to avoid this error, you can use Configuration Activity / SSCUI "Manage Default Account Assignments" to assign a default assignment to the Cost Elements.
