How does the Harvest tab work from the Box Builder?

After you have built your boxes in the Box Builder:

Click on the harvest tab in order to assign sources for each of your items. Click Edit in the upper right corner, choose a primary and secondary source for each item (one of your producers), and save changes.
Then, download the Sourcing Breakdown report to see the total amount that needs to be harvested and from where you plan to source each of your items.
If you don't see a producer that you need in the list of sources, click here to learn how to create producer profiles. You may create producer profiles for each of your fields.
