• What is the cause and solution for SAP error message AXT_COMMON147 - Cannot convert &1 to the requested data type; &1 is negative ?

  The SAP error message AXT_COMMON147 indicates that there is an issue with data type conversion, specifically when trying to convert a negative value to a data type that does not support negative numbers. This typically occurs in scenarios where a numeric value is expected to be non-negative, such as when converting to an unsigned integer or when dealing with certain data types in SAP that do not allow negative values.
  Cause:
  
  Negative Value: The primary cause of this error is that the value being processed is negative, and the target data type does not accept negative values.
  Data Type Mismatch: There may be a mismatch between the source data type and the target data type, leading to conversion issues.
  Business Logic Error: The negative value may not be valid in the context of the business logic being executed, indicating a potential error in data entry or processing.
  
  Solution:
  
  Check Input Values: Review the input values being processed to ensure that they are valid and non-negative where required. If the value is negative, determine if it should be corrected or if the logic needs to be adjusted.
  Data Type Review: Verify the data types being used in the program or function module. Ensure that the source data type can be converted to the target data type without issues.
  Adjust Business Logic: If the negative value is valid in some contexts, consider adjusting the business logic to handle such cases appropriately, possibly by using a different data type that can accommodate negative values.
  Debugging: If you have access to the ABAP code, use debugging tools to trace where the error occurs and inspect the values being processed at that point.
  
  Related Information:
  
  Data Types in SAP: Familiarize yourself with the different data types in SAP ABAP, especially those that are signed (allowing negative values) and unsigned (not allowing negative values).
  Error Handling: Implement error handling in your code to manage unexpected values gracefully, providing meaningful messages to users or logging errors for further analysis.
  SAP Notes: Check SAP Notes and documentation for any known issues or updates related to this error message, as there may be patches or recommendations from SAP.
  
  By addressing the root cause of the negative value and ensuring proper data type handling, you can resolve the AXT_COMMON147 error effectively.
