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

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