Changing Discrete Job's Requested Start Date via backend

Hi,

I'm creating a simple Discrete Job re-scheduling program to re-schedule discrete job start date by changing its Requested Start Date.

When I tried directly on ERP, I checked the table and notice the table changed was WIP_DISCRETE_JOBS with following columns: SCHEDULED_START_DATE, SCHEDULED_COMPLETION_DATE, REQUESTED_START_DATE along with last update log columns.

It's safe if I directly update that table? is there any other related table to be checked too? or concurrent to running so the date change can be done without causing errors?

Thanks
