Problem Experts OWB 10gR2 - Mapping with OMB - Give a name to the flat file

Question

I'm trying to create a mapping in OWB by using the Experts (OMB),
where the data source is a database table and the target is a flat file (to transform a table to a flat file).
The tasks of my Experts :
This task create a mapping, and add a existing table on it.
     OMBCC '$thepath'
     catch {OMBDROP MAPPING 'M1'}
     OMBCREATE MAPPING 'M1'
     OMBALTER MAPPING 'M1' \
     ADD $INITIAL_LAUNCH_CONTEXT_TYPE OPERATOR '$thetable' \
     BOUND TO $INITIAL_LAUNCH_CONTEXT_TYPE \ '$INITIAL_LAUNCH_CONTEXT' \
This task change the context and create a flat file
     OMBCC '/PRJ_LABO_PHARMA/SRC_FILE'
     catch {OMBDROP FLAT_FILE 'NEW_FILE'}
     OMBCREATE FLAT_FILE 'NEW_FILE' \
     SET PROPERTIES (DATA_FILE_NAME) VALUES('fichier_genere.txt')
This task add the flat file to the mapping, and create a connection between the source (table) and the target (flat file)
     OMBCC '/PRJ_LABO_PHARMA/MOD_SRC_LABO'
     OMBALTER MAPPING 'M1' \
     ADD FLAT_FILE OPERATOR 'NEW_FILE'\
     BOUND TO FLAT_FILE '/PRJ_LABO_PHARMA/SRC_FILE/NEW_FILE' \
     OMBALTER MAPPING 'M1' \
     ADD CONNECTION FROM GROUP 'INOUTGRP1' OF OPERATOR '$thetable' \
     TO GROUP 'NEW_FILE' OF OPERATOR 'NEW_FILE' COPY ALL
This task update the flat file structure
     OMBRECONCILE MAPPING 'M1' OPERATOR 'NEW_FILE' \
     TO FLAT_FILE '/PRJ_LABO_PHARMA/SRC_FILE/NEW_FILE' \
     USE (RECONCILE_STRATEGY 'REPLACE', MATCHING_STRATEGY 'MATCH_BY_OBJECT_ID')
Then I have a task which execute this mapping.
Everything is good, but during the execution I have a error VLD-2357 : The target file's name is not indicated for the file NEW_FILE.
I don't know how to give a name to the flat file in OMB.
Help me please.
Best regards

Just like if you built this in the UI where you would have to configure the flat file operator and define a target data file name and possibly the location these properties should be set in scripting.
Set the property TARGET_DATA_FILE_NAME to the name of the data file.
Something like....
OMBALTER MAPPING 'M1' \
MODIFY FLAT_FILE OPERATOR 'NEW_FILE' SET PROPERTIES (TARGET_DATA_FILE_NAME) VALUES ('my_datafile.csv')
