• What is the cause and solution for SAP error message MDG_MDF8103 - Field &1 cannot be converted without loss of data: &2 ?

  The SAP error message MDG_MDF8103 indicates that there is an issue with data conversion in the Master Data Governance (MDG) module. Specifically, it means that a field (denoted by &1) cannot be converted to the target data type or format without losing some data (denoted by &2). This typically occurs when there is a mismatch between the data types or when the data being processed exceeds the limits of the target field.
  Cause:
  
  Data Type Mismatch: The source field may have a different data type than the target field. For example, trying to convert a string to a numeric type where the string contains non-numeric characters.
  Length Exceedance: The data in the source field may exceed the maximum length allowed for the target field. For instance, if the source field has a string of 50 characters and the target field can only accommodate 30 characters.
  Precision Issues: If the source field is a decimal number with more decimal places than the target field can handle, this can also lead to data loss during conversion.
  Invalid Characters: The source data may contain characters that are not valid for the target field type.
  
  Solution:
  
  Check Data Types: Verify that the data types of the source and target fields are compatible. Ensure that the source data can be converted to the target data type without loss.
  Adjust Field Lengths: If the issue is related to length, consider increasing the length of the target field if possible, or truncate the source data to fit the target field.
  Data Cleansing: Clean the source data to ensure it only contains valid characters and formats that can be converted to the target field.
  Mapping Configuration: Review the mapping configuration in the MDG process to ensure that the fields are correctly mapped and that any necessary transformations are applied.
  Error Handling: Implement error handling in your data processing logic to catch such issues early and provide meaningful feedback to users.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like MDGIMG to access the configuration settings for MDG or SE11 to check the data dictionary for field definitions.
  Data Model: Review the data model in MDG to understand the relationships and constraints between different fields.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide additional guidance on handling this error.
  Testing: After making changes, conduct thorough testing to ensure that the data conversion works as expected without any loss of information.
  
  By addressing the underlying causes and implementing the suggested solutions, you should be able to resolve the MDG_MDF8103 error effectively.
