Hi, Of course there will be no difference in available disk space before and after the execution, because SAS cleans up after executing (joining) and uploading the results. But you also write, you were monitoring while ETL is executing. Also it might be possible, that you have used small datasets, and everything happened in the memory of the SAS Workspace Server. Some options that can help monitoring: options sastrace=',,,d' sastraceloc=saslog; options fullstimer; options msglevel=i; Also check the UTILLOC option. Sometimes it points to a different location than WORK. Could you attach the code that was generated by DI Studio?
