• What is the cause and solution for SAP error message MDS_LOAD021 - Load GUID &1 already exists in table &2 ?

  The SAP error message MDS_LOAD021 indicates that there is an attempt to load a GUID (Globally Unique Identifier) that already exists in the specified table. This typically occurs during data loading processes, such as when using the Master Data Services (MDS) or during data migration activities.
  Cause:
  The error is caused by the following scenarios:
  
  Duplicate Data: The GUID you are trying to load already exists in the target table. This can happen if the data being loaded is not unique or if there was a previous load that inserted the same GUID.
  Incorrect Data Preparation: The data being loaded may not have been properly cleaned or deduplicated before the load process.
  Concurrent Loads: If multiple processes are trying to load data simultaneously, they might conflict with each other, leading to duplicate GUIDs.
  
  Solution:
  To resolve the MDS_LOAD021 error, you can take the following steps:
  
  
  Check for Duplicates:
  
  Before loading the data, check the target table for existing entries with the same GUID. You can run a query to identify if the GUID already exists.
  
  
  
  Data Cleansing:
  
  Ensure that the data you are trying to load is unique. Remove or modify any duplicate entries in your source data.
  
  
  
  Modify Load Process:
  
  If the data is expected to have duplicates, consider modifying the load process to handle duplicates appropriately. This could involve updating existing records instead of trying to insert them.
  
  
  
  Use Upsert Logic:
  
  If applicable, use an "upsert" (update or insert) logic in your data load process. This way, if the GUID already exists, the existing record will be updated instead of causing an error.
  
  
  
  Check Load Configuration:
  
  Review the configuration settings of your data load process to ensure that it is set up correctly to handle existing records.
  
  
  
  Log and Monitor:
  
  Implement logging to capture details about the load process, which can help in diagnosing issues in the future.
