Lot stages can be changed at any point in time from the Lot Details Page. Lot stages should be changed whenever the lot is complete with one phase of its life, such as finishing primary fermentation and moving to malolactic fermentation. Stages are primarily helpful for reporting; when you are working with lots or viewing lots in a report or Explorer, you can always filter the lots by Stage.
This article covers how to change the stage of a lot:
From the Lot Details page
Click on the blue pencil next to your current stage to select a new stage.
From within an action or work order task
Stages can be selected within actions and tasks. For example, when going through the Process Fruit to Tons task, you can select to change the Lot Stage at the conclusion of that task.
Go to the Lot Explorer and click on the Manage Lots button in the top right corner. Select Set stage across lots.
Choose your lots from the lot picker, then select a stage from the Stage dropdown. Click on Set Stage to change the stage for the selected lots.
