Hi Marc,
Did you tried the last step given in the note you mentioned,
The extension is completed! Should the system not yet display the new field in the output, this is either due to a special buffer mechanism of the field catalogs for the output (read Note 122975 for this) or due to the fact that the new field is not yet filled (read Notes 359691 and 327821 for this).
please check the note 122975 in quality system and revert.
Regards,
Pavan
