In order to map or associate a purchase account with your production tracker - like a beef purchases account - the account type must be direct cost.

You can change an accounts type in Figured without affecting your accounting software or without needing to make the change in the accounting account first.

Head to Accounting > Chart of accounts and search for the name of your purchase account.

Click on the name of the account, and on the screen that follows you'll want to change the accounts type to direct cost.
