It is possible to customize and save the displayed columns in a Full Log Detail report once it is run. But, as it takes long to run, I would like to retain the format for future use.
Follow the steps below:
1) Go to the Reports tab and run the Full Log Detail report.
2) Right click on any of the column headers and "deselect" all the columns you want to remove.
3) Click on the "Save As" button to save the report with a name of your choice under the "Shared Reports".
4) Go back to the Reports tab and find your new custom report under the "Shared Reports Group".
Run the report. The customized column layout is now retained.
