In software, sandboxes are essentially a copy of your system where you can change things and see how it would affect your system without making any changes. So if you wanted to try out a different configuration but wanted to test it out before going ahead, the sandbox is a perfect place for the test run.However, be warned that you can’t push these changes into your existing system. Once you refresh, they’re gone forever. So make sure you document what you want and what you’ve done so you can replicate it on your ERP.The sandbox is based on your backups. So it needs to be updated whenever you make significant system changes. This is a manual process that Acumatica does charge a fee for.
