Let's recap how versioning works in Pegasus:
A version of your report is saved when Submitted for Review
A version of your report is also saved when that Submitted Report is Approved, so every Approved Report should have at least two versions: a Submitted copy and Approved copy
If a Submitted Report is Rejected and Re-submitted, another version is saved
If a Report is Un-Approved and then Re-Approved, another version is saved
How to View Field Report Versions
Navigate to the Field Reports page and select a specific Field Report in the grid.
From the side blade widget, select the Version History tab.
Select a Report Version from the drop down menu. In the example below, you'll see a Submitted Version and Approved Version.
After selecting a report version. You can either view the PDF copy of the version selected or email a PDF copy to a recipient.
