Issue
Processes are not saving and updating the value input to the ‘Assumed volume per annum’ field under the ‘Timeframes’ tab.
Error Code
For example, where a value of '2' was input to the ‘Assumed volume per annum’ field and the value goes back to '0' after saving the process.
Resolution
The issue happens when the feature 'Enable Process Costs' under Admin > Configure > Process Timeframes is turned OFF on a site. To resolve this issue, the feature just needs to be turned ON. Then after inputting a value to the ‘Assumed volume per annum’ field it will update to the correct value after saving a process.
