In SAS Enterprise Guide, if you replace your SAS Server after importing
a file, and then attempt to reimport your data on the new server, you
may receive the following error:

   ERROR: Physical file does not exist

   or

   ERROR: No logical assign for filename #XXXXXX

This typically happens when you import a file on one server and run
Tools -> Replace SAS Server to change the processing SAS server for your
project. The import is still trying to import the original file from the
first server which does not exist on the second server.

You can workaround this problem using one of the following methods:

  1) After you replace the SAS Server, save the project, close SAS
  Enterprise Guide.  Then reopen SAS Enterprise Guide, and rerun the
  import task.  This will sometimes use the correct server.

  2) Another workaround is to recreate the Import Data task on the
second
  server. After you run Replace SAS server, select File -> Import Data
to
  reimport the exact same data from your second SAS server.  In the new
  Import task, specify the exact same output dataset as you have in the
  original import. When you run this it will automatically generate an
  arrow to your existing file in your process flow. After the import has
  run successfully on the new server, you can remove the old Import Data
  task and data from your Process Designer.

Please note: if you do not have any tasks that follow the output table
from your Import task, then when you remove the old Import Data task and
data, it will probably delete the newly created data also. If this
happens, rerun the Import task one more time and the data should be
recreated. If you have a task dependant on the output table, then when
you delete the old Import task and data, the remaining part of the flow
should automatically attach to your new flow.
