Get orders from Live cache

Hi,

I want to find out how many orders do we have in the live cache by orders.

I have

BAPI_MOSRVAPS_GETLIST3 to get Planned/Production orders together.

But I want to get the number of Planned orders and Production orders seperately. How can I get that?

I have BAPI_POSRVAPS_GETLIST3 to get Purchase requisitions/orders.

How can i get a breakup of how many each are?

Also I want to find out how many "Manual Reservations" are. is there a FM or BAPI for this?

Thanks.
