Auto Scheduling for Planned orders

We are unable to get the finish dates in the planned order unless we schedule it manually. How can we configure the planned order to be scheduled automatically as soon as they are created? Our sales orders are allocation via APO and planned orders need to be scheduled right away.

In OPU5, "Scheduling" and "generate capacity requirements" are checked under the "Detailed scheduling" section.In the "Adjust Scheduling" section, we have selected "via detailed scheduling" also.

Any help is greatly appreciated.

Thanks!
