No. But you can see which extractions have been accepted by Splunk and from what application.
At the command line from SPLUNK_HOME/bin run the following command;
./splunk cmd btool list --debug
Where is props, transforms etc. In your case those will most likely be the two to look at. On *nix systems you could do splunk cmd btool props list --debug >> output to dump the output to a file to make it easier to review. All entries will have the APP that they are present within prefixed to each line.
Otherwise, if it is a search time extraction you can comment out all of the REPORT or EXTRACT lines in props and slowly re-introduce them. On 4.3 each time you run a search it will reload the search time extractions so there is no need to restart each time you comment or uncomment one line.
