Hi,

I was following my professor's instruction video using a replacement node with data set PVA97NK. When I ran the replacement node after making changes, a red border encircled the PVA97NK input node. The error message from the input  node (when I ran it again) is "Library is not assigned. You can allocate this library in your project start up code." 

 

When I went to the original data source, which I have been successfully working with for several weeks, the error message was: "The Underlying Table for this data source does not exist. " 

 

Interestingly, a second data source not associated with PVA97NK also shows that same "Underlying Table...does not exist" error although the diagram from this second data source still runs with no errors.

 

 

 

I have been using both data sources and diagrams for several weeks with no issues. 

 

My Assignment is due at 2:00 tomorrow - any ideas what happened - where to look for clues, etc.

 

Thank you!

Patricia

The highlighted text makes me think that somehow you have closed the library reference. Hopefully a proper LIBNAME statement, or equivalent menu choices, should get the library back.

Thank you for the reply - I had already looked through SAS Studio prior to posting to ensure the Libname and associated EM folders were intact and they were -- but the LibName in the Start Code had been deleted. Several other replacement nodes had successfully run during this same session so, maybe some errant keystroke happened when I launched the third Replacement Node 3 "Run" procedure??? I restored that Start Code and everything is functioning...

 

Once I get the homework submitted, I'm going to replicate running the replacement node exercise to see if anything happens to the Start Code Libname again.
