I would like to track the change of cost of a product in the inventory module. For example, if someone changes the cost from 50 to 60, I would like it to appear in the chatter or somewhere that is easy to access. For example : "The cost has been changed from 50 to 60 on 4th December 2020". It would be nice if I could also make a graph from the changes based on months.
I have tried using audit trail, but it tracks the changes of all the fields. I am only interested in the change of the cost of product. Track_visibility only tells me that the cost has been changed, but it doesn't tell me from which value to which value. I would still like to know the previous value of cost even after updating the value. Is this possible?
