It is possible to correct a posted sales Invoice in Business central. But it is not possible to correct a posted Service Invoice. Out customer aksed us to check if it is possible to have the same function in the posted service invoices to correct a posted service Invoice document. We think this needs to be in Standard Dynamics 365 Business Central.
