Somewhat odd way to use DI-studio, I would create a Stored Process with parameters, that users run in EG.
One way of doing it in DIS is to create a user written transform with a option called year and then use the macro variable of that option to filter your data in your DIS job.
The user will not be prompted, but can at least choose year from a drop down box...
If you make the options mandatory and leave it blank, the user can't run the job whitout setting the option, but as I said an odd way of doing it....
For DI Studio 3.4, see chapter 9 in the users guide.
For details about Stored process, see the "SAS Stored Processes: Developer's Guide" section under "Integration Technologies" in the online doc library.
