I am wondering where do i enter my recipes ( the ones from the store when I buy a product or material ) I was wondering where do i go? I thought this program would be easey like accounting for dummies LOL can someone help.

I lost my data and now I am re-entering it but now when I re-enter my invoices it tells me that I can't enter befor my fiscal year. How can i by pass this so I can enter all my invoices.
