Overview:
While viewing a report in Vault, the ability to use bulk actions is not available from the Action menu.
Root Cause:
This problem occurs when the report uses Grouping. It is not possible to Bulk-action a report that has Grouping.
Solution:
Edit the report to remove the Grouping and run the report. It is possible to do this without saving the report. Run the Bulk action, and do not Save the report to retain the desired grouping.
