Introduction
A client reported the error “Date is not valid” when running Depreciation on their Fixed Assets register and as it took a little while for me to find the solution I thought I’d share 🙂
The Error
The client had been running depreciation without issues when they suddenly started receiving the error below:

I checked dates being used for the Depreciation job and this seemed fine. I also checked the regional date settings in the “User Settings” page but again all looked fine.
After investigation several new assets had been imported without a “Depreciation Starting Date” on the Depreciation book.
I therefore updated “Depreciation Starting Date” and re-ran the Depreciation and it went through fine.
Only a short post but hopefully will help someone else who encounters this issue.
Thanks for reading!
