  The SAP error message DMC_DTL008 indicates that there is an attempt to add an entry for an object that already exists in the mass transfer process. This typically occurs in the context of data migration or data transfer processes, particularly when using the Data Migration Cockpit (DMC) or similar tools.
  Cause:
  The error occurs when:
  
  You are trying to transfer or upload data for an object (e.g., a material, customer, vendor, etc.) that has already been included in the mass transfer process.
  There may be duplicate entries in the source data that you are trying to upload.
  The system is designed to prevent duplicate entries for the same object in the mass transfer process to maintain data integrity.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check for Duplicates:

  If duplicates are found, remove them from your data file before attempting the upload again.
  
  
  
  Review Mass Transfer Process:
  
  Check the mass transfer process to see if the object has already been included. If it has, you may need to update or modify the existing entry instead of trying to add a new one.
  
  
  
  Use Unique Identifiers:
  
  Ensure that each object has a unique identifier (like a key or ID) that distinguishes it from others. This will help prevent such errors in the future.
  
  
  
  Consult Documentation:
