Issue about use SEGW to register Odataservice to Gateway hub

Issue Desc: 1.use Z305924 to lon on A4H. 2.use SEGW to register Odataservice to Gatewayhub(NPL system) 3.popup a error message. Action have been done: 1.Use SM59 to test RFC destination NPL_BGRFC_DEST, connection test is ok,remote log on is ok. Error message: Could not connect to the selected system. Check log for details. Message no. /IWBEP/CM_SBLMTOOLS015 Diagnosis The following errors might have occurred while connecting to the selected SAP Gateway hub system: Communication failure, System failure System Response Could not connect to the selected system..

Hey dear lxj2007499, The reason is, the RFC connection NPL_BGRFC_DEST is not working properly. When you check the definition of NPL_BGRFC_DEST, you'll see it's not a trusted connection, and hard coded with user name FIORIRFC with password. When you try testing 'Remote login', it popped up a logging screen which is not correct   Now when you go to NPL to check the user FIORIRFC, you'll see it was locked due to incorrect login  Checked the user change history to see when it was locked, which was long time ago on Apr. 27th  Considering this user FIORIRFC has high privilege and was defined as a service type of user, so at this time we don't want to unlock it. Instead you may want to use the trusted RFC from A4H to connect to NPL, so here I'll change the RFC NPL_BGRFC_DEST to trusted RFC  Now testing the SEGW again, still failed  Check the logs  So missing authorizations. Now we add these authorization into the roles. **Please note that when the user LEO1 try to register gateway from A4H, the actual authorization failure is happening in the target system that connected via RFC, which is NPL**  Add the authorization to NPL developer role  Now retry SEGW in A4H, still failed, missing following authorization about table maintenance  We have no concerns to allow developers to change all these tables. So add auth group IWAD into S_TABU_DIS  Now try SEGW again in A4H, finally successful.
