This error typically occurs in the context of Master Data Governance (MDG) for Material Management when you attempt to create a new material group with a key that is already in use.
  Cause:
  
  Duplicate Entry: The material group you are trying to create has the same identifier (key) as an existing material group in the system.

  Incorrect Input: The input data may have been incorrectly entered, leading to an attempt to create a material group that already exists.
  
  Solution:
  
  
  Check Existing Material Groups: Before creating a new material group, check the existing material groups in the system to ensure that the one you are trying to create does not already exist. You can do this by using transaction codes like MM01 (Create Material) or OMD1 (Maintain Material Groups).
  
  
  Use a Different Identifier: If you confirm that the material group already exists, consider using a different identifier or name for the new material group you want to create.
  
  
  Data Validation: Ensure that the data you are entering is correct and does not inadvertently match an existing material group.
  
  
  Consult Documentation: Review the relevant SAP documentation or guidelines for creating material groups to ensure compliance with naming conventions and other requirements.
  
  
  Check for Active Change Requests: If you are using MDG, check if there are any active change requests that might be causing conflicts with the material group creation.
  
  
  System Synchronization: If you suspect synchronization issues, ensure that all systems are properly synchronized and that there are no pending changes that could lead to conflicts.
  
  
  Related Information:
