can we execute the sql to delete the data directly from table MRP_SCHEDULE_DATES?

We have third party planning system which need feed the MPS output data into the MPS Entries, every time we need delete the old data in MRP_SCHEDULE_DATES for a specific MPS designator then feed the new data through MRP_SCHEDULE_INTERFACE.

So in our customized program, can we execute the sql to delete the data directly from table MRP_SCHEDULE_DATES.

Like Delete * from MRP_SCHEDULE_DATES where schedule_designator = 'MPS_US'.

Thanks.
