• What is the cause and solution for SAP error message MDG_MAT_LOADER_MSG007 - Class &1 assignment to material &2 exist; overwrite not allowed ?

  The SAP error message MDG_MAT_LOADER_MSG007 indicates that there is an attempt to assign a class to a material that already has an existing class assignment, and the system is configured to prevent overwriting this assignment. This is a common issue when working with Material Master Data in SAP Master Data Governance (MDG).
  Cause:
  The error occurs due to the following reasons:
  
  Existing Class Assignment: The material already has a class assigned to it, and the system does not allow overwriting this assignment without specific permissions or configurations.
  Data Governance Rules: The MDG system may have rules in place that prevent changes to certain fields or attributes once they have been set, to maintain data integrity.
  Incorrect Data Load: During data load processes (e.g., using the MDG Material Loader), the data being uploaded may contain class assignments that conflict with existing data.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Check Existing Class Assignments:
  
  Use transaction code MM03 to display the material and check its current class assignments. If the material already has a class, you may need to decide whether to keep the existing class or remove it.
  
  
  
  Modify the Data Load:
  
  If you are using a data load process, ensure that the data being uploaded does not attempt to overwrite existing class assignments unless that is the intended action. You may need to adjust your data file accordingly.
  
  
  
  Use Change Mode:
  
  If you need to change the class assignment, ensure you are using the correct mode (e.g., change mode) that allows for modifications to existing data.
  
  
  
  Consult with Data Governance Team:
  
  If there are specific governance rules in place, consult with your MDG or data governance team to understand the policies regarding class assignments and whether exceptions can be made.
  
  
  
  Error Handling in Data Load:
  
  Implement error handling in your data load process to capture and log such errors for review, allowing for manual intervention if necessary.
  
  
  
  Review Configuration:
  
  If you have the necessary permissions, review the configuration settings in MDG that govern class assignments to see if adjustments can be made to allow overwriting under certain conditions.
