Hi Manoj and Caetano,
Thanks for your replies.
Finally we have concluded the scenario some thing like below.
Scenario re-cap.
The header material planned order scheduling should automatically determine or re-schedule the down line planned orders. Collective order scenario has been used for all the down line materials.
After MRP run, if the header planned order has been re-scheduled, then as a immediate next step MRP to be run manually to reschedule the down line planned orders or the nest MRP run batch job will take care of this. Also an another option would be is to do reschedule of the header planned order at the time of conversion (to production order) and and do scheduling at the collective order header which will automatically re-schedule all the down line orders.
Regards,
Chinna
