In SAS 9.4M7, the FEXIST and FILEREF functions do not return the correct values when used with the FILENAME SFTP access method statement.

Here is sample code that triggers this issue:

If the file exists, the FEXIST function should return a value of 1 and the FILEREF function should return a value of 0. 

If the file does NOT exist, the FEXIST function should return a value of 0 and the FILEREF function should return a nonzero value such as -20006.

For more information about another issue with the FILENAME SFTP statement, see SAS Note 69404.

A hot fix is planned for this issue.
