The standard system contains a Business Add-In that provides an interface for integrating additional postal checks of the address data through external tools. This Business Add-In is called Address-Check.
This example uses the data element INTCA (ISO code of the country). Since SAP recommends complying with the international ISO standard for country-specific queries, you should use the data element INTCA also for Business Add-Ins. The ISO code of a country key would be, for example, US instead of USA.
Before the Business Add-In is called from within the application program, you must determine the ISO code of the country by submitting a SELECT statement to table T005 (field INTCA). Then you can pass the filter value as an exporting parameter.
