I've created an XY Event Layer, and now I want to copy that to a shape file.  It works fine on the first iteration, but crashes on the second iteration.  What seems odd, when looking in my geodatabase, the first shapefile is not named correctly; it is just called "shp", but I'm trying to name it "Data_20130626.shp".  Is there a problem in my naming syntax for ShapeName?

Thanks for any help you can provide!

The whitepaper on ESRI's shapefile spec establishes an '8.3' naming convention, meaning 8 characters for the name, 3 for the file extension...so either try shortening the name or use a gdb fc format.

Here's the Shapefile Specification:
http://www.esri.com/library/whitepapers/pdfs/shapefile.pdf

"...start with an alphanumeric character (a�??Z, 0�??9), followed by zero or up to seven characters (a�??Z, 0�??9, _, -)."

For example, maybe simply '20130625.shp'...etc., or if you want something more 'informative', give a more sensible descriptor for the name and store the date somewhere else.
