Hello All,
Yesterday we got an error while reconfiguring STMS. We were getting RFC_MODIFY_R3_DESTINATION error for TMS self RFC. Everything tried, like reconfiguring STMS with SAP_ALL user, assign SAP_ALL profile to TMSADM but nothing help. Finally we got solution “1730407 - Internal error in TMS communication 5”. In systems SAP note # 1640531 was applied but SAP note # 2132461 was not applied in any of the systems. So finally we applied SAP note # 2132461 in all affected systems and issue resolved.
So if you get similar issue please verify if SAP note # 1640531 is applied if yes then check for SAP note # 2132461.
