Each financial year companies/charities will have a different goal for a campaign. I can only currently change the goal which does not reflect goals in previous years which then affects the reporting on previous years.
This has been brought up a few times on here since 2017 and is a fairly standard financial need for a CRM.

Absolutely!! Incredibly frustrating that this has not been sorted out. The suggested solution is to have to recreate campaigns and approaches every single year with a new title including the year in the description!
