• What is the cause and solution for SAP error message 5D049 - Name affix & is not allowed for additional type & ?

  The SAP error message 5D049 indicates that there is an issue with the naming convention of an additional type in the system. Specifically, the error message states that the name affix (prefix or suffix) used for the additional type is not allowed. This typically occurs in the context of defining or modifying data types, structures, or other elements in the ABAP Dictionary.
