Incorrect record format: incoming file does not contain <CR/LF>

What causes this issue?

You have selected data record format '0' ('Record Delimited by <(>
<<)>CR/LF>'). However, the imported file does not contain the character
string <(><<)>CR/LF>. Therefore, the data records of the file cannot be
separated from each other.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Select a different data record format, or adjust the file to be imported
accordingly.
