Expose an FM or RFC as an http url (invoke FM by opening url in browser)

Question

Hi,
We have a function module e.g. Z_PROCESS_ORDERS, it does not have any import parameters, and there are no export parameters. the FM basically performs some action in SAP. e.g inserting a value a ztable.
is it possible to invoke this FM over the internet url.
I am not speaking about webservice.
I am talking about a plain http url. something like: http://sapserver:xxxx/blahblah/Z_PROCESS_ORDERS/xyz/something
if anyone clicks or opens this url in Internet explorer, the FM should be invoked in sap.
i searched on sdn, and found that webservice is an option, but to invoke it we need a webservice client or consumer proxy.
but my end user doesnot have that, and he wants just a IE link (http link) to invoke this function.
let us know webdynpro abap could serve this purpose.
thanks in advance,

Answer 1

the browser window should be closed
you can use an exit plug in your WDA App and provide a little javascript in the SICF-node of your app, that closes the window
or should display a message "the FM is invoked, you can close this window"
Simply use a TextView UIElement on your default view
Kind regards
