While creating an account or an account site:
If you choose to use an existing address and the existing address is invalid, Receivables displays the Account Site Address area of the Create Account Site page in the update mode with an error message prompting you to correct the invalid address elements.
If you choose to create an address and the address you entered is invalid, Receivables displays an error message prompting you to correct the invalid address elements. In case you ignore the error message and click Apply, Receivables displays a Suggestions drop-down menu and does not let you create the address unless you either adopt the suggestion or enter a valid address.
Note: Receivables displays the Suggestions drop-down menu only if you have set up address validation appropriately.
