Article on "What is new in SAS EG 4.2" and also Help topic on Export in EG 4.2 say that when you export a file as a step in a project, you can choose to replace any previous output or save the output with a time and date history. . But this does not seem to work even when the ""over write existing dataset" box is not selected. It always overlays the existing file. Is that a bug or am I interpreting the feature wrong?
