gATP: Product allocation against forecast

Hi experts,

I am working on a simple demo forproduct allocation in gATP. I want to demonstrate sales order entry against product allocation. I went through all customizing steps for product allocation in IMG SCM APO. But unfortunately I do not see any quantities passed from ECC to APO in planning area. I expect to see the qunatities from sales order entry in them month derivedx from mateial availability date (MBDAT).

Did I missed something here?

Thanks for your support.
