  The SAP error message MDG_BS_MAT_DATA_REP002 indicates that there is an issue with key mapping for a customer in the Master Data Governance (MDG) system. This error typically occurs when you are trying to replicate or synchronize data, and the system cannot find a corresponding key mapping for the specified customer.
  Cause:
  The error is caused by the absence of a key mapping entry for the customer in the MDG system. Key mapping is essential for ensuring that the system can correctly identify and link records between different systems (e.g., between the MDG system and the ERP system). If a key mapping does not exist for a customer, the system cannot proceed with the operation you are attempting.
  Solution:
  To resolve this error, you need to create a key mapping for the customer in question. Here are the steps to do this:
  
  
  Access the Key Mapping Transaction:
  
  Go to the transaction code for key mapping in your MDG system. This is usually done through the MDG application or a specific transaction code (e.g., MDGIMG or MDG_MAT).
  
  
  
  Create Key Mapping:
  
  Navigate to the section for key mapping.
  Enter the relevant details for the customer, including the source system and the corresponding key in the target system.
  Save the key mapping entry.
  
  
  
  Verify the Mapping:
  
  After creating the key mapping, verify that it has been correctly set up by checking the mapping table or using any available reporting tools in MDG.
  
  
  
  Retry the Operation:
  
  Once the key mapping is created, retry the operation that triggered the error message.
  
  
  
  Related Information:
