Hello,
In MD62 you have an option to split Weekly forecast. Go to tab page: Sched. lines, menu: Edit -> Split perd online.
In OMPH here you can define Split your Forecast for MRP. You need to execute MD67 for the same with the period split
Also you can use the period lot size like WK it will create order for a week.
Best Regards,
