Hi Venu,
At table ROOSFIELD, enter data source name and keep SELECTION as "A". execute the it check the out put. if you won't get list mean no fields are hidden.
again check the table contents, remove SELECTION "A" and just enter data source name and display table out put.
What ever the field are in that table those fields will be visible at RSA6(other than Hidden fields).
if not showing like that, if you see fields at LBWE, maintenance , Right side pane Communication str.
Move them to left.
Even if not seen what you need, then deactivate data source. again activate data source from RSA5 and do as you done at first time. do this on dev system only.
Thanks
