Doubt in client proxy

Hi All,

I am trying to do the client proxy scenario, my scenario is to fetch the material data from R/3 and place it in a file. from material master i am taking 4 fields data matnr,mbrsh,mtart,meins and created a program to fetch the data for those fields. please find the code below

REPORT ZABAP_PROXY.

DATA : Proxy TYPE REF TO ZDEV1CO_MI_MATERIAL_OB. " Class name

DATA : It TYPE ZDEV1MT_MATERIAL. " outbound interface name

DATA : It_mara like mara occurs 0 with header line.

CREATE OBJECT proxy.

TRY.

SELECT * from MARA into table It_mara where ersda eq sy-datum.

loop at it_mara.

move-corresponding : it_mara to it-Mt_Material.

endloop.

CALL METHOD PROXY->EXECUTE_ASYNCHRONOUS

EXPORTING

OUTPUT = It.

COMMIT WORK.

CATCH cx_ai_system_fault.

DATA fault TYPE REF TO cx_ai_system_fault.

CREATE OBJECT fault.

WRITE:/ fault->errortext.

In order to test this scenario i am doing in the following way.

first i am executing my abap program and then going to tcode sproxy and choose our outbound message interface and execute then i will get the one screen where i will input sender service , sender name space sender interface and checked the check box generate template data and i am getting the data in the file in destination system byt iam getting data as This is a string 1, this is a string 2 .. etc. but not the actucal data from material master. knidly syggest me the way i am following is correct or wrong and provide me some solution for this

Thanks in advance.
