I have a program that I'm trying to run but before it even gets through the actual program this is the warning I get and I get no output to excel. There are no errors, just this warning.  What reason(s) could there be for this? I ran the program before and it ran fine and output data.

We can't see from what you have posted, where the macro variable _PROGRAM is defined. I'm assuming that is done earlier in your program. Please post the complete SAS log so we can see what is going on.
