Reports with custom metadata

Hi team ,

I am trying to generate reports via OOB Asset reports.

I am accessing the URL http://localhost:4502/mnt/overlay/dam/gui/content/reports/createreportwizard.html ​ to generate the reports.

The problem i am facing is that on the "custom columns" section i need to add the "related" info for an asset (i.e) source , derived & others etc.

Please let me know the steps to include the related info of the assets in the custom columns section.

Thanks

Harish
