Just as a clarification, the help files state that you can also import from a .txt file; however, when I attempt to do so, I am receiving the attached error message. I can replicate this error on our Avtex production CIC system, as well as on a customer system. This error occurs even when you do the following:
1. Export a current volume forecast.
2. Open exported volume forecast .tsv file in Excel.
3. Save the volume forecast in .txt format. (with no modifications).
4. Attempt to import the .txt file.
Thanks for your help!
