Input tool error with new line and commas

8 - Asteroid

I have just happened upon an issue with input tools when run using the AMP Engine.

Essentially, if a CSV file has a multi-line record that is usually denoted by double quotes and there is a delimiter in one of those new lines, then the AMP engine fails to read the file correctly.

I have attached an example of what I am experiencing to help demonstrate the issue, @TonyaS 


Any suggestions would be appreciated.


Can you please email with information about your issue? Someone from our support team can take a look at this with you.


It may be helpful to include the following information:

  3. Replication steps
  4. Frequency and severity of the issue
  5. Troubleshooting steps taken so far

Hi @DavidLane,


You need to check the AMP Only option to "Allow Newlines in Quoted Fields"...




Scanning for newline characters within fields within a buffer of text requires single-threaded reading. By default, we consider any line break to be a new record so we can perform multi-threaded reading.


Checking the config option in the screenshot resolves the issue. AMP will perform a single-threaded read.

@JeradR, that did the trick. I had not spotted that option as it was hidden at the bottom of a scroll menu.

Thanks for your help. David


Thank you @JeradR  I was just about to start looking for that other thread where you mentioned this when it came up previously.
