Hi Imran,

Please check the sapnote on this...

1. Delete all occurrences of SLD_UC/SLD_NUC:
   1. In case on NW 6.40/7.0
      Login to Visual Admin: Go to Server → Services → JCO RFC Provider
      Delete all occurrences of SLD_UC/SLD_NUC.
   2. In case of NW 7.1/7.2/7.3
      Login to NWA: Configuration management → Infrastructure → JCO RFC Provider
      Delete all occurrences of SLD_UC/SLD_NUC.
2. Ensure that same Gateway host and Gateway Port is maintained correctly at
   following location:
   1. SLD UI → Administration → Profile → Section= datasupplier
   2. Parameters=GatewayHost/GatewayService.
   3. Transaction RZ70 → GatewayHost/GatewayPort.
3. SLD_UC and SLD_NUC RFC destinations must not be created manually in SM59
   transcation.
   System automatically generates the SLD_UC and SLD_NUC RFC destinations as described
   in the section “ABAP Data Supplier (transaction
   RZ70)” of the note 1057720.”
