The SAP error message FINS_FI_MASS_DATA406 indicates that there is an issue with the naming convention of certain objects in the context of Central Finance. Specifically, it states that names starting with certain prefixes (indicated by &2 or &3) are reserved for Central Finance use, and therefore cannot be used for other purposes.
Cause: Naming Convention Violation: The error occurs when you attempt to create or modify an object (such as a cost center, profit center, or other financial objects) using a name that starts with a reserved prefix. These prefixes are typically reserved for Central Finance functionalities to avoid conflicts and ensure proper integration.
Configuration Issues: If your system is configured to use Central Finance, it may enforce these naming conventions more strictly.
Solution: Change the Name: The most straightforward solution is to rename the object you are trying to create or modify. Ensure that the new name does not start with the reserved prefixes
