pp and pm integration for capacity planning

Dear ALL,

Just now i started integration testing between pp and pm.

As we know PM equipment is work centre for PP.Suppose there is 1 machine MAC-1 for which i created maint. order also i ticked Sys. condition in MO and by using the same machine , Prd.dept is created Prod. Order.

But as per std. scenario , SAP should show that this capacity is not available for pp but in our case it is not happening and capacity is available here.

I would like to know is there any thing missing from my side.

Awaiting for your valuable suggesation.
