      Hello Jes ,

      After the process RZ70 completed system should create new SLD_NUC and SLD_UC connections , could you try to “Connection Test” for these entries on SM59 and check the error message , also during this time you can check RFC logs under work directory from OS level , additionally you can check the SMGW transaction logs for further info. SMGW –> GOTO –> Trace

      Best Regards.

    Hello Harjot ,

    Did you try RZ70 to create these SM59 entries again ?

  5. sapbasisinfo says:

    Also you can check the following OSS Note

  6. sapbasisinfo says:

    Did you check network connection and security settings ? Also if you didnt check , please check SM59 SLD definations with “test connection” activity…
