File does not exist or cannot be opened in BDC

Hi all,

I was trying to upload data using BDC. I recorded the creation of material and I have the data in notepad. I have created a BDC program. There are no errors and when I run it, I get the following.

I have created a text file and saved it in the desktop. I gave the data format as 'asc'. Should I change that? OR why am I getting like this?

Thanks in Advance,

Swetha
