You can define country-specific validation rules on any element of your address style. Validation rules determine the information you can enter in these address elements. The validation rules Oracle Receivables uses to verify your address information during address entry depend on the following:
your home country and the country of the address you are entering
the address validation level you choose
the flexible address format and validation rules assigned to the country of the address you are entering
You define your home country in the Default Country field of the System Options window. Oracle Receivables uses this information to specify the home country for flexible address formats, and taxpayer id and tax registration number validation. It also provides a default value of the Country field when you enter addresses; however, you can override this value by setting the user profile option 'Default Country'. See: Overview of Receivables User Profile Options.
You can choose how Oracle Receivables will respond when you enter an invalid address. You can choose to display an error message, a warning, or simply choose 'No Validation'.
The Country field is the first field of the address region on every window because it determines the format and validation for the rest of the address fields.
If you implement the Flexible Address Formats feature, when you enter a value in the Country field that has been assigned to an address style, a window opens with the address elements defined for that style. See: Flexible Addresses.
