    Possible Reasons:

    1. Some fields for the backend system used to setup the JCO destination are not updated properly (i.e.

    empty) in SLD.

    2. Ensure that the SLD is setup properly. Click on the u201CTest Connectionu201D to check that the SLD is up and running.

    Check section "NullPointerException in the trace when maintaining JCO destinations" in below SDN document:
