  The SAP error message MDG_HDB_MAT_SEARCH004 indicates that there is an issue with the mapping of a model attribute to a reuse component in the Master Data Governance (MDG) system, specifically in the context of material search functionality. This error typically arises when the system cannot find a corresponding mapping for a specific attribute in the data model to the reuse component that is expected to handle it.
  Cause:
  
  Missing Mapping Configuration: The most common cause is that the mapping between the model attribute and the reuse component has not been defined or is incomplete in the configuration settings.

  Custom Development: If there are custom developments or enhancements, they may not have been properly integrated with the standard mappings.
  
  Solution:
  
  
  Check Mapping Configuration:
  
  Go to the MDG configuration settings and verify the mapping of the model attributes to the reuse components. Ensure that all necessary attributes are correctly mapped.
  Use transaction code MDGIMG to access the configuration settings.
