Cost distribution: When lots are combined in the system, whether that be through movements such as blending, topping, racking, etc, there can be losses. These losses do not carry cost; the system concentrates the cost into the remaining volume.
To write off costs due to losses: If you do have an event where the losses need to carry the cost (ie. shrinkage) a volume adjustment needs to be recorded with the reason selection "Losses other than inventory". This will classify the cost as shrinkage and will be reported on the Cost Over Time report.
Cost reporting when a lot is tracked in weight: Lot cost breakdown will not be reported on in the system until after primary fermentation when the actual yield is known (lots tracked in weight are pressed off and therefore tracked in volume). If a lot's contents are in weight, the lot cost will not compute until all the associated lots are in volume units. This applies for not only the child lot but all parent lots as well.
As an example:
The cost information will be "pending" for Lot C and Lot D until LotD is converted to volume (the actual yield). The system needs to understand the volume distribution of Lot A between Lot C and Lot D before it can distribute the $5,000 fruit cost between the two.
