https://communities.sas.com/t5/SAS-Enterprise-Guide/EG-4-2-Export-as-data-step-in-project/m-p/67388#M6764 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?

If you export to a file system location, the exported file name should have a date-time stamp appended to make it unique.<BR /> <BR /> Chris Fri, 12 Mar 2010 15:07:07 GMT https://communities.sas.com/t5/SAS-Enterprise-Guide/EG-4-2-Export-as-data-step-in-project/m-p/67389#M6765 ChrisHemedinger 2010-03-12T15:07:07Z
