Summary : 
      SAP Note highlights issues with transporting organizational units with addresses from systems with Release <4.6 to systems with Release >=4.6 where addresses are not imported. This occurs because from Release 4.6 onward, a new logical transport object (R3TR TDAT ADDRESS_4.6) is utilized, replacing the older object (R3TR TDAT ADDRESS). SAP advises against such transports due to potential inconsistencies. If unavoidable, manual entry of addresses in the target system or creating a dedicated transport including all R3TR TABU entries for address tables with generic keys is recommended. Attention must be paid to specific corrective measures to mitigate data loss risks.
