• What is the cause and solution for SAP error message MDG_MAT_LOADER_MSG020 - Classification rejected; material & exist in staging area ?

  The SAP error message MDG_MAT_LOADER_MSG020 indicates that the classification of a material has been rejected because the material already exists in the staging area. This typically occurs in the context of SAP Master Data Governance (MDG) when you are trying to load or create a material master record, and the system detects that there is a conflict with an existing record in the staging area.
  Cause:
  
  Existing Material in Staging Area: The material you are trying to create or update already exists in the staging area, which means it has not yet been fully processed or approved.
  Duplicate Entries: There may be duplicate entries for the same material in the staging area, leading to conflicts during the classification process.
  Data Inconsistencies: There might be inconsistencies in the data being loaded, such as incorrect classification data or missing mandatory fields.
  
  Solution:
  
  
  Check Staging Area: 
  
  Navigate to the staging area in your MDG system and check if the material already exists. You can use transaction codes like MDG_MAT or relevant reports to view the staging area.

  Approval Process: 
  
  Ensure that any existing records in the staging area are either approved or rejected. If they are pending approval, you may need to complete that process before loading new data.
  
  
  
  Data Validation: 
  
  Validate the data you are trying to load. Ensure that all required fields are filled out correctly and that the classification data is accurate.
