What's the difference between the receipt date at the receipt line and receipt header level?

The application uses the receipt date at the line level (Receive Lines or Receive Line pages) for accounting and invoicing purposes. This becomes the receipt's transaction date. Receipt Accounting, Payables, and Cost Management use this date.

The receipt date at the header level (Create Receipt or Add to Receipt pages) may be used for analytics in the future.

You must capture both receipt dates when creating receipts in the UI. The receipt dates at the receipt header and receipt line level both default to the current date. The GL Date on the Create Receipt and Add to Receipt pages also defaults to the current date. You can change all of these dates. However, it's the receipt date at the line level that's used for accounting and invoicing.
