What's the Intercompany checkbox on the AP invoice page and how's it different from the Intercompany Cross Charge checkbox?

The Intercompany Invoice checkbox is automatically checked for AP invoices during the invoice validation process, if the supplier on the invoice has an intercompany setup against the provider organization that initiates the transaction.

The field helps users quickly identify that the invoice is between different entities within the same group and is grayed out, indicating that it cannot be modified directly. It also helps with reconciliation and tracking intercompany balances. For invoices with this field enabled, the AP invoice validation process overrides the liability account derived from the supplier setup with the Intercompany Payables account specified in Intercompany Balancing rules. The Intercompany Cross Charge checkbox is checked manually by an AP user on the external vendor invoices, to automate the cross-charge treatment directly from AP invoices.
