Text File Warning - Set the value of Parallel Process Threads to {None}

Hi,

DS Version 4.1 SP2

Post migration our jobs which run from text files all receive the following warning:

The file <XXX.csv> has a text delimeter specified.

If row delimeters are quoted within the text delimeters, set the value of the "Parallel Process Threads" option to {None}

This occurs every day on every file..

However, the "Parallel Process Threads" option is already set to {None} - i have tried resetting it to 0, but it just sets itself back to {None}

Does anyone now how to get rid of these warnings?

Many Thanks

HS
