You can only copy over a permit if it is the same permit type and for the same property.
Navigate to the Contractor module / Contractors Tab / Work Permits / You will see the copy button which is highlighted in the red box below on the screenshot:
This will copy over all of the information from the previous permit and you can then amend the shift date/time and any other sections of the permit apart from the permit type and site name. There is also a tab to show any other permit files that have been copied over from the original permit which will reduce having the same files attached to the permit. You can see this tab highlighted in yellow below:
When copying a Work Permit which has files attached to it, click onto the ‘Attached Files’ tab whcih is visible in the Work Permits – Copy wizard. Within this view, you can review the existing attachments and remove as appropriate.
