Country code not visible in Address book search and select screen during PO/Req creation

Dear All

In JDE 9.2.5 , during purchase order entry , if I try to search and select the supplier number , the screen that appears is P0101SL (Address Book Long Address Number search). Here , there's no country code field visible even after selecting the display address option. Also , there is no option to display BU field.

Is there a constraint/technical justification to neither display the country code nor the BU?

Also , other than customization , is there a way to make country/BU visible in the search and select screen?

Kindly share your thoughts , much appreciated.
