For the procedure described here you must first enable full communication with the gateway. Based on the log file written, adjust the security settings in the secinfo and reginfo files.
gw/sec_info = $(DIR_DATA)/secinfo
gw/reg_info = $(DIR_DATA)/reginfo
gw/logging = ACTION=S LOGFILE=gw_log-%y-%m%d SWITCHTF=day
If an SAP system consists of multiple application servers, add the system ID (three-letter SID) and the server name to the file name. This enables the files to be identified when they are collected centrally for analysis. You can use the environment variables $(SAPSYSTEMNAME) and $(SAPLOCALHOST) to set the parameter as follows:
gw/logging = ACTION=S LOGFILE=gw_log_$(SAPSYSTEMNAME)_$(SAPLOCALHOST)-%y%m%d SWITCHTF=day
This logs all security-relevant gateway actions in a separate file. You can also make this setting within the system.

secinfo contains line USER=* HOST=* TP=* only
reginfo contains line TP=* only
With this configuration of secinfo and reginfo all programs can be started from the gateway, and all programs can register in the gateway.
These settings are only temporary and are used for finding out which programs are to be included in the files. While these settings are active, the gateway is not protected against external programs.
