Configure the RZ70 for sending data via RFC (SLD_UC and SLD_NUC)

Problem :

Error "TP_REG_ACCESS_DENIED (thRc=748)" when opening an RFC connection


Procedure :

1. Configuration in SLD

        Go to: SLD UI -> "Administration" -> "Settings" -> Section: "datasupplier"

Note :
Exactly this hostname and service name should be specified on ABAP side, in the RZ70.

2. Configuration in RZ70

3. Configuration in the SLD's gateway

                    3.1. gw/acl_mode = 1 must be set in the instance profile of SLD's gateway.

                    3.2. The reginfo file must contain suitable rules for registering SLD_UC or SLD_NUC TP program to register on the SLD's gateway

                         [ABAP]
                         -via SAP GUI connection:
                          "smgw"-> "Goto" -> "Expert Functions" -> "External Security" -> "Display reginfo"

                         [Java ]
                         -at os (gwmon.exe)

                           gwmon nr=<sysnum>
                              -->m  (menue)
                               -->9 (security informations)
                                -->3 (display reginfo)


 REGINFO file format

                      #VERSION=2
                      P TP=SLD_UC HOST=<SLD Application server host> CANCEL=<SAME AS "HOST">,local  ACCESS=<ALL systems pushing information to SLD Server>
                      P TP=SLD_NUC HOST=<SLD Application server host> CANCEL=<SAME AS "HOST">,local ACCESS=<ALL systems pushing information to SLD Server>
                      ... .
                      P TP=* HOST=local CANCEL=local ACCESS=local
                      P TP =*HOST=internal CANCEL=internal ACCESS=internal

               3.3. After modifying the reginfo file, gateway security must be reread:

                        [ABAP]
                        -via SAP GUI connection:
                           "smgw" -> "Goto" -> "Expert Functions" -> "External Security" -> "Reread"

                        [Java ]
                        -at os (gwmon.exe)
                            gwmon nr=<sysnum>
                            -->m  (menue)
                             -->9 (security informations)
                              -->4 (refresh security)

4. Restart the SLD.

Suggestion:
Delete the rfc SLD_UC and SLD_NUC from SM59 before sending the data.
