The process responsible for updating/refreshing extracts is called the "Backgrounder", and has its own set of logs on the server that can probably help you out.
Further, whenever an extract fails on the server, it should cause an Alert in the upper menu bar of the server itself - clicking on the alert shows you the specific error (if available), along with the connection information that the server is trying to use to update the data. That's always the first place I look when an extract fails.
Of course, the regular list of culprits also applies:
-What is the data source that you're trying to extract from? Is it a Database? A Flat File?
-"Where" is it located? If it is a flat file, is it on the same machine as your server?
-How "Big" is the extract? How much data are you trying to pull back?
Thanks for replying.The server settings has not been altered
Thanks for replying. Strange thing is that there are no alerts on the server. Let me check the log files mentioned
You can check below mentioned logs for more details.
