Using the 'Plan Customer Projects' (ID: F0719) app, it's not possible to save the billing plan when creating projects with XXX currency – which is different than the customer's standard currency – due to the error "You cannot save the billing data. Please contact support".

Without the billing plan saved, the Sales Order for service (SO01) cannot be generated.

SAP S/4HANA Cloud Public Edition

The currency exchange rates are not maintained correctly or not maintained at all.

Using the app 'Currency Exchange Rates' (ID: F3616), maintain the currency exchange rate from the currency planned to be used in the project to the customer's standard currency.

Note: the validity of the currency exchange rate should cover the project start date (duration).
