    Hi Praveen,


    NullPointerException.


    Some value you are getting null.


    Means check this below line number for VcloadComp.java:368.


    java.lang.NullPointerException: while trying to invoke the method com.xxx.sap.wd.xxx.comp.vcupload.wdp.IPublicVcUploadComp$IZaak_ResultsElement.getEx_Description() of a null object loaded from local variable 'elemResult'

    at com.sap.wd.pload.comp.vcload.VcloadComp.populateChoosenCase(VcloadComp.java:368)

    BR,

    Durga Rao.
