  The SAP error message MDG_BS_MAT_SP028 indicates that a material is already maintained in a specific plant and storage location. This error typically occurs in the context of Material Master data management, particularly when using SAP Master Data Governance (MDG) for materials.
  Cause:
  The error is triggered when you attempt to create or change a material record in a plant and storage location where the material already exists. This can happen due to:
  
  Duplicate entries being created inadvertently.
  An attempt to create a new material with the same plant and storage location as an existing one.
  Data inconsistencies or issues in the material master data.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Material Records:
  
  Use transaction codes like MM03 (Display Material) to check if the material already exists in the specified plant and storage location.
  Verify the material number, plant, and storage location to ensure you are not duplicating an existing entry.
  
  
  
  Modify Existing Material:
  
  If the material already exists and you need to make changes, use MM02 (Change Material) to update the existing material record instead of trying to create a new one.
  
  
  
  Review Data Entry:
  
  Ensure that the data you are entering is correct and does not conflict with existing records. Double-check the material number, plant, and storage location.
  
  
  
  Consult with Your Team:
  
  If you are unsure about the existing records or need to create a new material, consult with your team or the data governance team to clarify the requirements and avoid duplication.
  
  
  
  Data Governance Procedures:
  
  Follow your organization's data governance procedures to ensure that material master data is managed correctly and that duplicates are avoided.
  
  
  
  Related Information:
