This functionality stopped working in IFS Cloud because of command Plsqlap_Server_API.Invoke_Record_Impersonate is giving errors that is no longer supported. Or more specifically, the Batch_Transfer_Handler is no longer supported in IFS Cloud.   To quote Here is the full line:
Plsqlap_Server_API.Invoke_Record_Impersonate('BatchTransferHelper', 'readFromFtp', AM, activity_ => TRUE);

So the main issue is that we need to get the fetching and sending of attached document again. Additionally FTP based document managent is being phased out and is being replaced by a "FileStorage" type. We want this script to work in either FTP or Filestorage connected documents.
 

This is the code:
