scheduling in semifinished product structure
I have a multi level semi-finished product structure. For example my work hours are between 07:00-17:00 and my semi finished products are produced in 3 hours.
I created a planned order for the top level for example in 30.06.2011. It make the schedule starting at 14:00 and finish at 17:00. MRP created the dependent requirement for the low level semifinished product in the same day and created a planned order again starting at 14:00 and finish at 17:00. So in the lower levels it made the scheduling for all the semifinished products in the same day. But I want the program to work like in second level it makes the planning between 10:00-14:00, third level between 07:00-10:00 and fouth level 29.06.2011 between 14:00-17:00. How can I solve this problem.
