KM678 - Details

• The SAP error message KM678 indicates that there is an overlap in the account intervals defined in the system. This typically occurs in the context of controlling (CO) or financial accounting (FI) when you are trying to define or modify account intervals for cost elements, cost centers, or other financial objects.
