In codeunit 365 "Format Address", integration event OnBeforeGetCompanyAddr(RespCenterCode: Code[10]; var ResponsibilityCenter: Record "Responsibility Center"; var CompanyInfo: Record "Company Information"; var CompanyAddr: array[8] of Text[100]; var IsHandled: Boolean),

allow the parameter RespCenterCode to be passed by reference (i.e. prefix method declaration with var) so that we can dynamically set the Responsibility Center from the calling function and thus format the correct responsibility center address, even when "Responsibility Center Code" is not set on the calling document header.
