gw/sim_mode SAP Parameter attribute - start simulation mode for reg_info and sec_info

gw/sim_mode is a SAP Parameter attribute which is used to control start simulation mode for reg_info and sec_info information. This is available within R/3 SAP systems depending on the version and release level.

Below is the standard documentation available and a few details of the attributes values .

Until now, it has been possible to use SAP Note 1425765 to create a reg_info or a sec_info file based on the data in SM59 (more precisely: in table RFCDES). The Access Control List (ACL) files created in this way can be activated immediately during productive operation, but this does not guarantee that the start behavior is correctly mapped in the ACL files for dynamic RFC destinations or connections between two external programs through the gateway. That is, malfunctions often occur during productive operation if these files are immediately put into operation. If you assign the value 1 to the parameter, the gateway processes the rules in reg_info and sec_info as follows: o If an applicable PERMIT rule is found, the request is permitted, as previously. o If an applicable DENY rule is found, the request is denied, as previously. o If NO applicable rule is found, the request was previously denied. Now, in this "fallthrough" case, the request is permitted and a specific entry is written to the gateway log file defined with gw/logging (see SAP Note 910919).
That is, all start attempts (sec_info) or registrations and communication with registered programs (reg_info) that are not explicitl y specified in rules are permitted (gw/sim_mode = 1) or continue to be forbidden (gw/sim_mode = 0, default).
