Update on WF_ITEM_ATTRIBUTES on name = 'CO_S_PROMISED_DATE' does not work

Hi,

I have updated the WF_ITEM_ATTRIBUTES for the name = 'CO_S_PROMISED_DATE' so that changing the promise date will not require re-approval but it is still not working.

our version is on 11i

here is my script:

update WF_ITEM_ATTRIBUTES

set NUMBER_DEFAULT = 365

where item_type = 'POAPPRV'

and name = 'CO_S_PROMISED_DATE';

thank you.
