• What is the cause and solution for SAP error message PU189 - Cannot transport ADO objects for Unicode systems ?

  The SAP error message PU189 "Cannot transport ADO objects for Unicode systems" typically occurs when there is an attempt to transport ADO (ABAP Data Objects) objects in a Unicode system. This error is related to the handling of character encoding and data types in Unicode environments.
  Cause:
  
  Unicode Compatibility: ADO objects may not be compatible with Unicode systems. This is because ADO objects were primarily designed for non-Unicode systems, and their transport may lead to issues with character encoding.
  Transport Request Issues: The transport request may contain objects that are not supported for transport in a Unicode environment.
  Incorrect Configuration: There may be configuration issues in the transport landscape or the system settings that prevent the transport of ADO objects.
  
  Solution:
  
  Check Object Types: Review the objects included in the transport request. Ensure that they are compatible with Unicode systems. If ADO objects are included, consider removing them from the transport request.
  Use Unicode-Compatible Objects: If you need to transport data or objects, ensure that you are using Unicode-compatible objects or alternatives.
  Adjust Transport Settings: Check the transport settings in the SAP system. Ensure that the transport landscape is correctly configured for Unicode systems.
  Manual Transport: If necessary, consider manually transporting the ADO objects or recreating them in the target system instead of using the transport request.
  SAP Notes: Check for any relevant SAP Notes that may address this issue. SAP frequently releases notes that provide fixes or workarounds for known issues.
