Product Allocation Update

Dear SD Experts,

I have configured Product Allocation and is working.

But I have the following issues. When I check the actual planning version 000, the incoming order order quantity is not corectly updated.The incoming order quanity shows less than the actual incoming ordes.

Also the customer requirements and Open Product Alloc is not updated.

In transaction MC9C, the Total order qty is showing lesser than the total orders existing. Customer Requiremens,Requirements not covered,Open PA are showing zero values.

Please suggest me how to overcome this issues.

thanks and regards
