Hi Venkat

Please try to build a logic similar to below:

parameters: p_cus type kunnr,
            p_ven type lifnr,
            p_po  type ebeln.
data: tab type tabname.
            
start-of-selection.

   if p_ven is initial.
      tab = 'TABLE1'.
   else.
      tab = 'TABLE2'.
   endif.
   
   select fld1 fld2 
          into table itab
          from (tab)
          where (cond).

Kind Regards
