Hello, 

Does anyone know if there is a way to link invoices with their journal entries? I was told to try classes but the class ID column in our invoice line items table is empty so I can't do a query to join the tables. I do know these Journal Entries are linked to their Invoices because if I visit Quickbooks, you can see which invoice the journal entry is linked too so I don't know why there's no foreign key I can use to join them when creating a query. Any advice you might have is appreciated. Thanks!
