Generic RFC function modules

Hello,

assume you have a Web AS and a mySAP ERP-system which are connected to each other. On the ERP system there's a table "A" and you need parts/columns of the table on the Web AS, furthermore "A" could not be known on the Web AS.

Is there a way to create a function module which has generic importing/exporting parameters to transfer the structure of "A" to the Web AS via RFC?

Thanks in advance.

Daniel
