title: SaveSvc() IN WSDL of Genexus
body: <p><img src="https://i.stack.imgur.com/fCA4O.png" alt="enter image description here"></p>
  
  <p>I am implementing WSDL with Genexus. 
  When I insert data into the Table, I use <strong>SaveSvc()</strong> default procedure.
  But I have a problem with this Procedure.
  Look at the picture, please
  It can do inserting only for <strong>parent table</strong> [Invoice].
  <strong>Child Table [Invoiceline] can't be inserted.</strong>
  So, I don't know how to solve this problem.
  Thank in advance.</p>
