• What is the cause and solution for SAP error message LTR2_RN_CHECK018 - Maximum mapping value '&1' exceeds range in receiver ?

  The SAP error message LTR2_RN_CHECK018 indicates that the maximum mapping value for a certain field exceeds the defined range in the receiver. This typically occurs in the context of data mapping or transformation processes, such as in SAP Data Services or SAP BW (Business Warehouse) when data is being loaded or transformed.
  Cause:
  
  Data Mapping Issue: The value being processed exceeds the maximum limit defined for the target field in the receiver system. This can happen if the source data contains values that are not compatible with the target schema.
  Configuration Error: The mapping configuration may not be set up correctly, leading to mismatches between source and target data types or ranges.
  Data Quality Issues: The source data may contain erroneous or unexpected values that do not conform to the expected range.
  
  Solution:
  
  
  Check Mapping Configuration:
  
  Review the mapping settings in the data transformation process. Ensure that the target field's data type and range are correctly defined.
  Adjust the mapping to ensure that the values being sent to the target do not exceed the defined limits.
  
  
  
  Data Validation:
  
  Validate the source data to identify any values that exceed the expected range. You may need to implement data cleansing processes to handle these outliers.
  Use data profiling tools to analyze the data and identify any anomalies.
  
  
  
  Adjust Target Field Definition:
  
  If appropriate, consider adjusting the target field's definition in the receiver system to accommodate larger values, if this is feasible and aligns with business requirements.
  
  
  
  Error Handling:
  
  Implement error handling in your data processing workflow to catch and log these types of errors, allowing for easier troubleshooting in the future.
  
  
  
  Testing:
  
  After making changes, conduct thorough testing to ensure that the issue is resolved and that no new issues are introduced.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for the specific module you are working with (e.g., SAP BW, SAP Data Services) for detailed information on data mapping and transformation.
  SAP Community: Engage with the SAP Community forums to seek advice from other users who may have encountered similar issues.
  Data Quality Tools: Consider using data quality tools that can help in profiling and cleansing data before it is loaded into the target system.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
