ABAP Structure - Table (name for line type)

Hi Abaper,

I created a simple web service with function module (remote enabled).

The WS works great but ...

I would like to adapt my XML structure (request).

Actually :

<REQ>

     <USERS>

          <item>

               <USERID>?</USERID>

          </item>

     </USERS>

</REQ>

What I would like :

<REQ>

     <USERS>

          <USER>

               <USERID>

          </USER>

     </USER>

</REQ>

In SE11 i have :

- ZWS_USERS (Structure)

-- USERS (Table type - ZTT_USERS)

--- ??? (Line type - ZLT_USER)

How to name the line ?

I want to replace <item> by <USER>

I can't find how to do that ... This is probably simple but ...

Thanks,

Youri
