Its not clear from your note whether you are trying to move data from a client to server (client is 'local') or from an attached drive (USB drive is 'local' to your machine where SAS Enterprise Miner is working).
Here are some things to consider:
* SAS Enterprise Miner can access data stored locally on the compute server or via a fully qualified network path relative to the compute server (e.g. \\myserver\myfolders\data)
* SAS Enterprise Miner cannot access data on USB attached 'local' drives or locations using mapped drive letters, even if the drive letter is mapped to a network path
To access data on a location other than a physical drive on the machine where SAS Enterprise Miner is processing, you must have the defined the network location relative to the compute server and you must have read/write permission to that location using the credentials used to access SAS Enterprise Miner. The read/write access is necessary since SAS Enterprise Miner will use that location to write out temporary files created during processing even though the original data will be unchanged.
The one exception to this rule is when you use the File Import node to import a file from your local machine to the server. When the File Import node runs, it creates a copy of the specified file in the project folder on the compute server. If the file in question is large, it is generally better to use your operating system tools to move the file to the server and place it in a location outside the project folder. Placing large data sets inside the project folder can slow processing.
Hope this helps!
