Function names while creating SAP adapter 6.5

I have a list of RFC function module that is to be used while creating a SAP adapter, and I am also able to view them in the drop down ‘Function name’ list.

My Question is - Do we need to create separate adapters for EACH function names (or) is there any way where we could dynamically specify thus creating only one adapter :confused:…Please someone guide me in creating this sap adapter.

Thanks
Sue

Any updates please…
Thanks
