When I run following Function with the following SETOF table...

it says:

NOTICE:  table "temp_production_product_operations" does not exist, skipping
CONTEXT:  SQL statement "drop table if exists 
temp_production_product_operations "
PL/pgSQL function "pb_report_temp_gerceklesme12" line 11 at execute 
statement

ERROR: set-valued function called in context that cannot accept a set
SQL state: 0A000
Context: PL/pgSQL function "pb_report_temp_gerceklesme12" line 56 at return 
next

Where is the error? I could not determined...
