• What is the cause and solution for SAP error message SV680 - Maintenance dialogs in function group &1 are not Unicode-enabled. ?

  The SAP error message SV680 indicates that there are maintenance dialogs in a specific function group that are not Unicode-enabled. This typically occurs when you are trying to run a program or transaction that requires Unicode support, but the function group in question has not been properly converted to support Unicode.
  Cause:
  
  Non-Unicode Function Group: The function group mentioned in the error message contains maintenance dialogs that have not been converted to Unicode. This can happen if the function group was created before the introduction of Unicode support in SAP.
  Legacy Code: Older ABAP code or function groups that were developed without considering Unicode compatibility may lead to this error when executed in a Unicode environment.
  
  Solution:
  To resolve this issue, you need to ensure that the function group is Unicode-enabled. Here are the steps you can take:
  
  
  Check Function Group: Identify the function group mentioned in the error message. You can do this by looking at the error details or logs.
  
  
  Convert to Unicode:
  
  Use the SAP transaction SE80 (Object Navigator) to open the function group.
  Check the maintenance dialogs (screens) within the function group.
  Use the transaction SE11 (Data Dictionary) to check the data elements and structures used in the function group for Unicode compatibility.
  If necessary, use the Unicode Conversion Tool (transaction SCC8) to assist in converting the function group to Unicode.
  
  
  
  Modify Code: If there are specific ABAP programs or screens that are not Unicode-compliant, you may need to modify the code to ensure it handles Unicode data types correctly. This includes:
  
  Changing character types from CHAR to STRING or C with appropriate lengths.
  Ensuring that string operations are compatible with Unicode.
  
  
  
  Testing: After making the necessary changes, thoroughly test the function group and its dialogs to ensure that they work correctly in a Unicode environment.
  
  
  Transport Changes: If you are working in a development environment, ensure that you transport the changes to the quality assurance and production environments after testing.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or tools for converting function groups to Unicode.
  Documentation: Refer to SAP documentation on Unicode conversion for best practices and detailed steps.
  ABAP Development Guidelines: Familiarize yourself with the guidelines for developing Unicode-compliant ABAP code to prevent similar issues in the future.
  
  By following these steps, you should be able to resolve the SV680 error and ensure that your function group is Unicode-enabled.
