I've been trying to design a new notification document, and did it by:
1) Exporting the "invoice" XML document
2) Editing it
3) Importing the "new invoice". XML document - under a new name/code for testing.
However, I've now realised I am unable to delete this new invoice document.
How can I delete imported notification documents? I couldn't locate the .xml file in the folder directories, and I'm also not sure if I did locate it, if just deleting it is ok.
