issue with segw transaction

Hi,

We developed a custom RFC instead of usinf standard BAPI for address since we have lot of custom fields to be updated from PA0006 table.

when i import custom RFC from segw transaction, how i need to map for GET_ENTITYSET and GET_ENTITY ,please explain.

and also how to pass filter parameters in URL for GET_ENTITYSET.

Thanks,
