The Job Type Accounts form allows you to create a list of G/L accounts that may only be used for expense type purchase orders and A/P bills for the Job Type.
Setting up a list of G/L account numbers for a Job Type would allow a user creating an expense item purchase order or when entering an A/P bill, to select from only the G/L accounts assigned to the Job Type.
If you do not want to limit your users to a selected list of G/L accounts, then do not enter any information into this form.
Creating a list of available G/L Accounts helps to minimize data entry errors.
