MDG_MDF122 - Details

• The SAP error message MDG_MDF122 ("The background job must finish first") typically occurs in the context of Master Data Governance (MDG) when a process is trying to access or modify data that is currently being processed by a background job. This can happen in various scenarios, such as during data replication, data validation, or when executing certain workflows.
  
  Cause:
  
  Concurrent Processing: The error indicates that there is a background job currently running that is locking the data or process you are trying to access. This could be due to data being updated, validated, or replicated in the background.
  Data Locking: SAP uses locking mechanisms to prevent data inconsistencies. If a background job is processing data, it will lock that data until the job is completed.
  Long-Running Jobs: If the background job takes a long time to complete, it can lead to this error being triggered when other processes attempt to access the same data.
