table parameters - webservice - urgent

Hello,

has anyone experience with table parameter in a rfc function module? When i try to expose a function module with table parameters as web service and use this webservice in WebDynpro i have the following problems:

- minoccurs-parameter in the generated webdynpro proxy is 1 although in the wsdl-document it is 0

- although i set data in the mapped context node for the table parameters and execute the webservice the table in the rfc module is empty.

- when the tables contains data after the execution of the function module the data is not passed to the WebDynpro application.

Any suggestion??

Thanks for your help!

Regards

Thomas
