• What is the cause and solution for SAP error message FL103 - Do not use 'umlaut' characters ?

  The SAP error message FL103, which states "Do not use 'umlaut' characters," typically occurs when a user attempts to enter data that includes umlaut characters (such as ä, ö, ü) in fields that do not support these characters. This can happen in various SAP transactions or data entry forms, particularly in fields that are not configured to handle special characters.

  Data Entry Guidelines: Ensure that users are aware of the restrictions on character usage in specific fields and provide guidelines for data entry.
