I have a custom record that gives us a list of laptops owned by the organization and the respective owners with other details. The current requirement is to add a field called ‘Current Value’, which will show the value of the laptop after deducting 20% per annum after the date of purchase. This part is fairly straight forward but what I am struggling to configure is the place where it will show the calculation in detail. For example, if a laptop worth £1000 is over a year old, the current value shows £800 but I need to show somewhere on the record that the current value is derived by reducing 20% from the original value. I was thinking of getting a sublist but was just wondering if there is a better way to achieve this. Thanks

I imagine you're thinking, create a custom record that is basically an audit record which stores the date it was generated / period it covers / old value / new value and show it as sublist to this custom record. That sounds like the approach I'd take, not sure what else would work better / easier to implement.

Are you depreciating these assets and recording that information in your books? If so, this requirement sounds like something that is best handled by the Fixed Assets bundle/module. You might want to check that out unless you're desperate to use your existing records or build something yourself.
