Problem execution web service which display a table

Question

Hi everybody,
I create a web dynpro appication which calls an Adaptative Web Service.
The associated RFC ZTEST_ROD takes 2 inputs parameters and delivers a table like this:
     - Field Import: MATNR type MATNR     WERKS type WERKS_D
     - Field Tables: TABLE_DEST like ZSTRUCT_ARTICLE
When i import the Webservice in WebDynpro, i have the following model binding:
Context:
  Request_ZTEST_ROD
     Response
          ZTEST_ROD_Response
               TABLE_DEST
                    Item
                         LABST
                         LGORT
                         MAKTG
     ZTEST_ROD
          MATNR
          WERKS
For The inputView, i link the context binding:
     ZTEST_ROD->MATNR and WERKS
For the ResultView, i link the context binding:
     Response->ZTEST_ROD_Response->TABLE_DEST->Item     LABST,LGORT and MAKTG     
and i create a table associated to Response->ZTEST_ROD_Response->TABLE_DEST->Item
At last, when i execute the application, i obtain the text:
"Exception on execution of web service on destination 'DEFAULT_WS_EXECUTION_DEST'
for operation 'ZTEST_ROD' in interface"
With NO information in the log defaultTrace.trc
Any suggestions about this problem ?
rewarded points ...
Thanks a lot!
Rodolphe

Hi Rodolphe,
I am not an expert in ABAP. Have a basic understanding of it. RFC have in itself, input parameters, output parameters
and Table parameters. Now whatever is defined as Table parameter can be used both for input and output.So you can pass
any number of records as input in this parameter and then RFC applies some business logic according to what input
you have provided in input and table parameter and send back the output in output parameters and as set of records in
same Table parameter.
In general it is not necessary that you give any input in Table parameter BUT if RFC is exposed as web service then due to some
reason it becomes necessary that whatever you have provided as Table parameter you should provide atleast one blank record
for each of the Table Parameter.
Hope I have not confused you.
