  The SAP error message /SMB/TYPES064 indicates that there is an issue with the import of a custom type in the SAP system. Specifically, it states that the custom type you are trying to import (denoted as &1) cannot be imported because an assignment with the same name (or a similar name) already exists in the system, identified by &2, &3, and &4.

  Duplicate Type Definition: The custom type you are trying to import already exists in the system, which leads to a conflict.
  Namespace Issues: If you are working in a multi-client environment or with different namespaces, there might be a naming conflict.
