The Field Extractor (FX) is a tool that helps you extract fields from your events using a graphical
interface2. You can create a report using a custom field extracted by the FX and share it with other users in
your organization2. However, if another user runs the shared report and no results are returned, there could be
two possible reasons. One reason is that the extraction is private, which means that only you can see and use
the extracted field2. To make the extraction available to other users, you need to make it global or app-level2.
Therefore, option C is correct. Another reason is that the other user does not have access to the index where
the events are stored2. To fix this issue, you need to grant the appropriate permissions to the other user for the
index2. Therefore, option D is correct. Options A and B are incorrect because they are not related to the field
extraction or the report.
