• What is the cause and solution for SAP error message MDG_BS_MAT_DATA_REP022 - Material &1 is rejected; key or value mapping information is missing ?

  The SAP error message MDG_BS_MAT_DATA_REP022 indicates that a material (identified by the placeholder &1) has been rejected due to missing key or value mapping information. This error typically occurs in the context of SAP Master Data Governance (MDG) when trying to replicate or synchronize material master data.
  Cause:
  
  Missing Key Mapping: The system requires a mapping between the source and target systems for the material data. If the key mapping (like material number, plant, etc.) is not defined or is incomplete, the replication process will fail.
  Missing Value Mapping: Similar to key mapping, if there are specific values (like units of measure, material types, etc.) that need to be mapped and they are not available, the system will reject the material.
  Configuration Issues: There may be issues in the configuration of the MDG system, particularly in the areas related to data replication and mapping.
  Data Quality Issues: The material data being processed may have inconsistencies or errors that prevent successful mapping.
  
  Solution:
  
  
  Check Mapping Configuration:
  
  Go to the MDG configuration settings and verify that the key and value mapping settings are correctly defined for the material data.
  Ensure that all necessary mappings are in place for the fields that are required for replication.
  
  
  
  Review Material Data:
  
  Check the material data that is being processed for any missing or incorrect values. Ensure that all mandatory fields are filled out correctly.
  Validate the material number and other key fields to ensure they are correctly defined in both the source and target systems.
  
  
  
  Use MDG Tools:
  
  Utilize the MDG tools to check for any inconsistencies or errors in the material data. This can include using the MDG data quality checks or validation tools.
  If necessary, run the data replication process again after correcting any identified issues.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for MDG to understand the specific requirements for key and value mapping for material data.
  Check for any notes or updates from SAP that may address known issues related to this error.
  
  
  
  Engage Technical Support:
  
  If the issue persists after checking the above points, consider reaching out to your SAP support team or consulting with SAP support for further assistance.
