A user is not able to export records less than 500.
Release : 16.0.2
Try one or more of the following steps:
1. Enable browser Developer Tools > Network to review if an HTTP error 500 is response is given.
If so, check if the user receives a browser popup message stating there is a slow-running script.
If so, select the 'Wait' option instead of cancelling the script.
2. Navigate to the cost plan and have the details/data finish loading.
If there is a view corruption, remove and re-add a column.
The view is not able to be rendered due to the script error.
3. Retry the Export to CSV.
