Smart SAP Assistant

• What is the cause and solution for SAP error message /BUILD/CORE003 - Error: During conversion to string. ?

  The SAP error message /BUILD/CORE003 Error: During conversion to string typically indicates that there is an issue with data type conversion in the ABAP program. This error can occur when the system attempts to convert a non-string data type (like a number or a date) into a string format, and the conversion fails due to incompatible data or unexpected values.
  Causes:
  
  Data Type Mismatch: The most common cause is a mismatch between the expected data type and the actual data type being processed. For example, trying to convert a numeric value that is out of range or not formatted correctly.
  Null or Uninitialized Variables: If a variable that is expected to hold a value is null or uninitialized, the conversion may fail.
  Invalid Characters: If the data being converted contains invalid characters that cannot be represented in a string format, this can lead to conversion errors.
  Incorrect Length: If the length of the data being converted exceeds the maximum length allowed for a string, it can cause this error.
  
  Solutions:
  
  Check Data Types: Review the data types of the variables involved in the conversion. Ensure that they are compatible and that you are not trying to convert an unsupported type.
  Initialize Variables: Make sure that all variables are properly initialized before they are used in conversions. This can help avoid null reference issues.
  Validate Input Data: Implement validation checks to ensure that the data being processed is in the expected format and does not contain invalid characters.
  Use Exception Handling: Implement error handling in your ABAP code to catch conversion errors and handle them gracefully, possibly logging the error for further analysis.
  Debugging: Use the ABAP debugger to step through the code and identify the exact point where the conversion fails. This can provide insights into the data being processed at that time.
