• What is the cause and solution for SAP error message BA120 - Automatic conversion is not necessary for structure & ?

  The SAP error message BA120, which states "Automatic conversion is not necessary for structure &," typically occurs in the context of data type conversions or assignments in ABAP programs. This message indicates that the system has detected that an automatic conversion of data types is not required for the specified structure, and therefore, the operation being attempted is unnecessary.
  Cause:
  
  Redundant Assignment: The error often arises when there is an attempt to assign a structure to another structure of the same type or compatible types without any need for conversion.
  Data Type Mismatch: It can also occur if there is an attempt to assign a structure to a variable that is already of the same type, leading to redundancy.
  Incorrect Data Handling: The program logic may be incorrectly structured, leading to unnecessary assignments or conversions.
  
  Solution:
  
  
  Review the Code: Check the lines of code where the error occurs. Look for assignments or conversions that are redundant. If the source and target structures are of the same type, you can remove the assignment.
  
  
  Remove Unnecessary Conversions: If you find that the conversion is not needed, simply remove the line of code that is causing the error.
  
  
  Check Data Types: Ensure that the data types of the structures involved are indeed compatible. If they are not, you may need to adjust the data types or the logic of your program.
  
  
  Use Explicit Conversion: If you need to convert between different types, consider using explicit conversion methods (like CAST or CONVERT) only when necessary.
  
  
  Debugging: If the error is not clear, use debugging tools to step through the code and identify where the unnecessary conversion is being attempted.
