• What is the cause and solution for SAP error message VSMI079 - Unable to convert quantity field without data loss ?

  The SAP error message VSMI079: Unable to convert quantity field without data loss typically occurs in the context of data conversion or processing where there is an attempt to convert a quantity field (usually a numeric field) that exceeds the allowable range for the target data type. This can happen in various scenarios, such as during data uploads, conversions, or when processing transactions.
  Cause:
  
  Data Type Mismatch: The source quantity field may have a larger range or precision than the target field can accommodate. For example, trying to convert a large decimal number into an integer field.
  Overflow: The value being processed exceeds the maximum limit of the target data type, leading to potential data loss if the conversion were to proceed.
  Incorrect Configuration: The configuration settings for the data types in the relevant SAP modules may not align with the actual data being processed.
  
  Solution:
  
  Check Data Types: Review the data types of the source and target fields. Ensure that the target field can accommodate the values being converted. If necessary, change the target field to a larger data type (e.g., from integer to decimal).
  Data Validation: Before performing the conversion, validate the data to ensure that it falls within the acceptable range for the target field. Implement checks to catch any out-of-range values before the conversion attempt.
  Adjust Configuration: If the error is related to configuration settings, review and adjust the relevant settings in the SAP system to ensure they are appropriate for the data being processed.
  Data Cleansing: If the data being processed contains invalid or out-of-range values, consider cleansing the data before attempting the conversion.
  Consult Documentation: Refer to SAP documentation or support resources for specific guidance related to the module or transaction you are working with.
