How to replace a function/procedure/trigger using datapump

Question

Hi All and thanks for any help you can provide!
My goal is to export our production schema -- table data, function and procedure definitions, triggers and sequences -- and import all of that into the QA schema.
Here is the expdp command from production
expdp / as sysdba
DIRECTORY=EXPORT_DATA
SCHEMAS=CP_APP
DUMPFILE=cp_app_01.dmp
LOGFILE=cp_app_01.log
I then move the file from the production server to the qa server and use this command to import it.
impdp / as sysdba
DIRECTORY=IMPORT_DATA
CONTENT=ALL
TRANSFORM=OID:N
DUMPFILE=cp_app_01.dmp
TABLE_EXISTS_ACTION=REPLACE
REMAP_SCHEMA=CP_APP:CP_QA
The problem is that triggers don't get built properly. Here's one error
ORA-39083: Object type TRIGGER failed to create with error:
ORA-00942: table or view does not exist
Failing sql is:
CREATE TRIGGER "CP_QA"."PLAYER_LOG_EMAIL_INS_TRIGGER"
before insert on cp_app.player_log_email
for each row
begin
-- auto-increment --
select seq_player_log_email.nextval into :new.log_id from dual;
end;
The REMAP_SCHEMA option only changes the schema of the trigger itself, but it did not affect the schema of the referenced table.
Any suggestions on how to get PL/SQL objects rebuilt?
Thanks for any help.

Hi,
this is a known issue and is also desribed in the manuals. There is a note on Oracle Support: "IMPDP Reports ORA-942 and ORA-39083 During Importing Schema Objects [ID 750783.1]". It describes a solution, in the simplest way:
Make an sql dump of the import, add the last parameter:
impdp / as sysdba
DIRECTORY=IMPORT_DATA
CONTENT=ALL
TRANSFORM=OID:N
DUMPFILE=cp_app_01.dmp
TABLE_EXISTS_ACTION=REPLACE
REMAP_SCHEMA=CP_APP:CP_QA
sqlfile=script.sqlNow you have the file script.sql in which you find your trigger code. Adjust in this file the schema names and run the code against the database.
Another option would be to adjust the trigger code in the source database to not reference the schema.
