REP-0118: Unable to create a temporary file Oracle's helpfile states this:
Quote:REP-118: Unable to create a temporary file.
Case 1: The environment variable that determines in what directory to create temporary files is set to an invalid directory.
Case 2: There is not enough free space on the disk to create the temporary file.
Case 3: A temporary file that cannot be modified already exist
In regedit under branch hkey_local_machine/software/oracle/<oracle home>
I have changed the variable REPORTS_TMP. I changed the value for this to c:\reports_tmp
or you can use something like this where you want Oracle reports to create temp files.
