When you are uploading files into PTX that are immediately failing with no error to explain as to why, one thing to consider is to look at the data file using notepad++ and you might find that there are “NUL” items at the end of each record:
The simplest workaround for this is to change the file extension to a “.dat” file.
All you need to do is open the file using notepad, click ‘file’ and ‘save as’, change the details as per the below (the filename itself is irrelevant).
Once this has been done, open the file again using Notepad++ and you will find that the “NUL” items are no longer in the file:
You should then be able to upload this file as normal and have it accepted /validated by PTX for
submission.
