• What is the cause and solution for SAP error message S_AUT122 - A conversion error has occurred ?

  The SAP error message S_AUT122, which states "A conversion error has occurred," typically indicates that there is an issue with data conversion in the system. This can happen in various contexts, such as when data is being transferred between different formats, or when there is an attempt to convert data types that are incompatible.
  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 string that contains non-numeric characters into a numeric type.
  
  
  Invalid Data Format: If the data being processed does not conform to the expected format (e.g., date formats, currency formats), it can lead to conversion errors.
  
  
  Null or Empty Values: Attempting to convert null or empty values can also trigger this error, especially if the conversion expects a valid value.
  
  
  Custom Code Issues: If there are custom ABAP programs or enhancements that manipulate data, they may contain logic that leads to conversion errors.
  
  
  Database Issues: Sometimes, issues with the underlying database, such as corrupted data or incorrect data types in the database schema, can lead to conversion errors.
  
  
  Solutions:
  
  
  Check Data Types: Review the data types of the fields involved in the conversion. Ensure that they are compatible and that the data being processed matches the expected format.
  
  
  Validate Input Data: Implement validation checks to ensure that the data being processed is in the correct format and does not contain invalid characters.
  
  
  Handle Null Values: Ensure that your code properly handles null or empty values before attempting any conversions.
  
  
  Debugging: If the error occurs in a custom program, use the ABAP debugger to step through the code and identify where the conversion is failing. Look for any specific values that may be causing the issue.
  
  
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as some conversion issues may be resolved in newer versions.
  
  
  Consult SAP Notes: Search the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide guidance on similar issues.
  
  
  Error Logs: Check the application logs (transaction SLG1) for more detailed information about the error, which can provide insights into what data caused the conversion error.
  
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like SE80 (Object Navigator) or SE37 (Function Module) to analyze the relevant code or function modules involved in the conversion process.
  SAP Community: Engaging with the SAP Community forums can provide additional insights and solutions from other users who may have encountered similar issues.
  Documentation: Review SAP documentation related to data types and conversion functions in ABAP to better understand how to handle conversions correctly.
  
  By following these steps, you should be able to identify the root cause of the S_AUT122 error and implement a solution to resolve it.
