View purchases from family sharing

That's a pretty broad question. If you mean your purchases:

Click on the link to 'See your purchase history in the App Store or iTunes Store' [iOS, computer, or web] - Does not include purchases made by others under Family Sharing; those have to be checked from their accounts. --> http://support.apple.com/HT204088

- Web: "To see charges from older purchases, you might need to look at your purchase history in Settings or the App Store."

- iOS device or computer: "If you want to see purchases that you made more than 90 days prior, tap Last 90 Days, then select a different date range."

If you're a Family Sharing organizer you should receive email receipts for items purchased by others in the Family if they end up being billed to your credit card.
