What's the name of FM for getting Sales Order Header / Item Status info

Question

Hello All:
Do you know what's the name of Function Module for getting Sales Order Header / Item Status Overview ? Any sample code will be very much appreciated.
Basically, I am trying to create a Webpage where user can enter the Sales Order document number and will return the Sales Order: Status Overview.
Thanks,
Dipankar Biswas

Thanks everybody ! Appreciate for your prompt response. I was also looking for some sample code, and I did find some on. And here is one. I still have to try the code, but here is for all your reference:
*& Report ZBAPI_SALESORDER_GETSTATUS *
*& Read and Display the Sales Order Items and Status of the Order *
REPORT zbapi_salesorder_getstatus NO STANDARD PAGE HEADING LINE-SIZE 200 LINE-COUNT 33(3).
