Hi Uday,
Can you also make sure that the internal table 'lt_cua_exclude' which you are using in the FM RS_SET_SELSCREEN_STATUS doesn't contain the function code 'ONLI'. If it contains the specified function code, please write a code in the AT SELECTION-SCREEN OUTPUT event to remove the code 'ONLI' from the table lt_cua_exclude and execute the report.
Thanks & Regards,
Sarath.
