FM called by macros in /SAPAPO/SDP94

Hi All,

I would like to create a FM which can be called my  macros in /SAPAPO/SDP94 to create planned production and I would like to pass over product, location, quantity and end date to the FM. From FM, I can only see product, location and quantity, don't see end date being pass over. Is there anyone has similar experience can light me on.

Thanks,
