• What is the cause and solution for SAP error message RSAR124 - Error in a data conversion in user-defined routine for record & ?

  The SAP error message RSAR124 indicates that there is an issue with data conversion in a user-defined routine during the data extraction process. This error typically occurs in the context of SAP BW (Business Warehouse) when data is being extracted from a source system, and it can be related to various factors, including data type mismatches, incorrect data formats, or issues within the custom logic defined in the user-defined routine.
  Causes of RSAR124 Error
  
  
  Data Type Mismatch: The data being processed may not match the expected data type defined in the routine. For example, trying to convert a string to a numeric type when the string contains non-numeric characters.
  
  
  Invalid Data Format: The data being extracted may not conform to the expected format. For instance, date formats or currency formats that do not match the expected input.
  
  
  Custom Logic Errors: If there is custom logic implemented in the user-defined routine, there may be bugs or logical errors that lead to the failure during data conversion.
  
  
  Null or Empty Values: The routine may not handle null or empty values properly, leading to conversion errors.
  
  
  Data Quality Issues: The source data may contain unexpected or corrupt values that cannot be processed correctly.
  
  
  Solutions to RSAR124 Error
  
  
  Check Data Types: Review the data types defined in the user-defined routine and ensure that the incoming data matches these types. Adjust the routine to handle any discrepancies.
  
  
  Validate Data Formats: Ensure that the data being extracted adheres to the expected formats. You may need to implement additional checks or transformations in the routine to handle different formats.
  
  
  Debug the User-Defined Routine: If you have access to the code of the user-defined routine, debug it to identify where the error occurs. Look for any logical errors or assumptions that may not hold true for all data.
  
  
  Handle Null Values: Modify the routine to include checks for null or empty values and handle them appropriately to avoid conversion errors.
  
  
  Data Cleansing: Perform data cleansing on the source data to ensure that it meets the expected quality standards before extraction.
  
  
  Log Error Details: Implement logging within the user-defined routine to capture detailed error messages and data values that lead to the failure. This can help in diagnosing the issue more effectively.
