Cannot use my imported Excel file

[Wenyan]

I imported excel file into the data, but I cannot choose this file to create a program.

I really do not know how can I deal with this.

Is there anyone can help with? Thanks

Are you able to do what you need if you right-click and load the table to memory?

Thank you for your reply. Since this is the first time to use my own data, I never do this before. Where can I click and load to memory?

If you right-click on the "TEST.sashdat" listing on the left, the context menu should include "Load".
