Select A sale may only be from a single batch if required.

You can choose to use a reference or date to distinguish between batches. This allows you to distinguish between stock that comes from the same batch but are created on different days.
For example, you may work in the food industry, producing food from the same batch of ingredients. By assigning a batch number as well as a use by date, you can ensure that your staff are able to identify the food that was produced first, so it can be sold first.
Enter the batch or serial numbers that you want to use in the Batch attributes area of the window.
The attribute is automatically marked as In Use as it is created.
