A certain SAP character occurs twice in a specific character set.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Each SAP character can appear once, at maximum, in a character set but
not several times, otherwise the character set cannot be unambiguously
decoded. For example, the SAP character "space" (blank) should not be
assigned the hex codes "32" and "33". Please maintain the character set
and remove the double coding of the character.

• What is the cause and solution for SAP error message TD328 - SAP character &1 is defined twice for character set &2 ?

  The SAP error message TD328 indicates that a character is defined more than once for a specific character set in the SAP system. This typically occurs in the context of character set definitions, where a character is assigned multiple definitions or mappings, leading to ambiguity.
  Cause:
  
  Duplicate Character Definitions: The character in question (&1) has been defined multiple times for the specified character set (&2).
  Configuration Errors: There may be errors in the configuration of character sets or in the transport of character set definitions between systems.
  Custom Modifications: If there have been custom modifications or enhancements to character sets, these could inadvertently introduce duplicates.
  
  Solution:
  
  
  Check Character Set Definitions:
  
  Go to transaction code SE78 (SAP ArchiveLink) or SE11 (Data Dictionary) to review the character set definitions.
  Look for the character (&1) in the character set (&2) and identify where the duplicates are defined.
  
  
  
  Remove Duplicates:
  
  If you find duplicate entries, remove or correct them to ensure that each character is defined only once for the character set.
  Ensure that the definitions are consistent and do not conflict with each other.
  
  
  
  Transport Requests:
  
  If the issue arose after a transport, check the transport requests to ensure that they do not contain conflicting definitions.
  If necessary, adjust the transport requests to remove the duplicates.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to character set definitions for any specific guidelines or best practices.
  
  
  
  Testing:
  
  After making changes, test the character set functionality to ensure that the error is resolved and that the system behaves as expected.
