• What is the cause and solution for SAP error message IU772 - Initial system is non-Unicode - Target system is Unicode ==> Unicode IMIG ?

  The SAP error message IU772 indicates that there is a mismatch between the character encoding of the source system (non-Unicode) and the target system (Unicode) during a system migration or data transfer process. This situation typically arises when you are trying to migrate data from a non-Unicode SAP system to a Unicode SAP system.
  Cause:
  
  Character Encoding Mismatch: The source system is using a non-Unicode character set, while the target system is set up to use Unicode. This can lead to issues with data integrity and representation, as non-Unicode systems can only handle a limited set of characters compared to Unicode systems.
  Data Migration Process: The migration process is not configured to handle the conversion of non-Unicode data to Unicode data, which is necessary for the target system.
  
  Solution:
  To resolve this issue, you need to perform a Unicode conversion of the data from the non-Unicode system before migrating it to the Unicode system. Here are the steps to achieve this:
  
  
  Use the SAP Unicode Conversion Tool: SAP provides a tool called the "Unicode Conversion Tool" (also known as the "SAP Unicode Migration Tool") that can help you convert your non-Unicode data to Unicode. This tool is part of the SAP system and can be accessed through transaction code SCC8.
  
  
  Follow the Migration Steps:
  
  Preparation: Ensure that you have a complete backup of your non-Unicode system and that you have planned the migration process carefully.
  Run the Unicode Conversion: Execute the Unicode conversion process using the appropriate transaction codes and tools provided by SAP. This typically involves running the SCC8 transaction and following the prompts to convert the data.
  Testing: After the conversion, perform thorough testing to ensure that all data has been converted correctly and that there are no issues with data integrity.
  
  
  
  Post-Conversion Activities: After the conversion is complete, you may need to perform additional steps such as adjusting custom programs, reports, and interfaces to ensure they work correctly in the Unicode environment.
  
  
  Related Information:
  
  
  SAP Notes: Check SAP Notes related to Unicode conversion for specific guidance, best practices, and troubleshooting tips. Some relevant notes may include:
  
  SAP Note 000000000000 (generic Unicode conversion notes)
  SAP Note 000000000001 (specific to your version or scenario)
  
  
  
  Documentation: Refer to the official SAP documentation on Unicode conversion for detailed instructions and considerations.
  
  
  SAP Community: Engage with the SAP Community forums to seek advice from other users who have gone through similar migrations.
  
  
  Consulting Services: If the migration process seems complex or if you encounter issues, consider reaching out to SAP consulting services or a certified SAP partner for assistance.
  
  
  By following these steps and utilizing the available resources, you should be able to resolve the IU772 error and successfully migrate your data from a non-Unicode to a Unicode SAP system.
