Once created and processed it generates a closing and an opening inventory for the product(s), which can be reviewed in the Inventories tab.
- Closing inventory removes product "current" inventory value (at current cost, either "average" or "standard")
- Opening inventory adds product "new" inventory value (at current cost, either "average" or "standard")
Whenever an inventory amount update is created on the current date, therefore movement date is the same as transaction process date, all existing transactions remains valued at the existing cost but new ones booked starting from current date, that will be valued at the new cost.
Whenever an inventory amount update is created in the past, those closing/opening inventories will have a movement date in the past and a transaction process date. These inventories will be set as "Backdated" transactions by the Costing Background process, therefore the corresponding backdated cost adjustment can be created.
