thanks sir,
iam not exactly saying select * from &c_table but some thing that like columns in select stmt also will be populated in user_parameters ,there are lot of table select.......from     mtl_demand md,     mtl_system_items msi,     mtl_txn_source_types     mtst,     mtl_item_locations loc     &C_source_from &C_from_cat
&c_source_from and &c_from_cat formula column and there are defined at report level only ......
pl/sql code &c_source_from is
function C_source_fromFormula return VARCHAR2 is
begin
if :P_source_type_id = 2 then return(',MTL_SALES_ORDERS mkts');
else if :P_source_type_id = 3 then return(',GL_CODE_COMBINATIONS gl');
else if :P_source_type_id = 6 then return(',MTL_GENERIC_DISPOSITIONS mdsp');
else if :P_source_type_id = 5 then
     if :C_source_where is null then
          return NULL;
     else
          return(',WIP_ENTITIES wip');
     end if;
else if :P_source_type_id = 8 then return(',MTL_SALES_ORDERS mkts');
else if :P_source_type_id is null then
return(',MTL_SALES_ORDERS      mkts,
MTL_GENERIC_DISPOSITIONS mdsp,
GL_CODE_COMBINATIONS gl ');
else null;
end if; end if; end if; end if; end if; end if;
RETURN NULL; end;
this is forumula column i hope that you understand what iam saying
please help me in this regard....
thanking you...
