Summary :
ABAP systems on NW 7.40 display instability in maintaining connections with MDM servers, identified by fluctuating connection statuses in SMGW transaction logs. RFC trace files reveal error message “TP_REG_SECU_ERROR” (RC 720), indicating unauthorized attempts from external server programs. The issue originates from absent or incorrect entries in the `reginfo` file, governed by the `gw/reg_info` parameter which defaults to blocking unlisted external registrations. Resolution involves correcting the `reginfo` file as per SAP Note #1069911, allowing required server programs to register freely without rebooting the gateway, using SMGW transaction for file updates.
