Problem with Binding tables to context nodes

Hi All,

I have a problem with binding tables to context nodes.

I'm using an RFC (FM1) that returns tables with GUIDs. I have to feed these tables as input to a different function module (FM2) for execution.

I tried to bind the tables returned from FM1 to FM2. I've used an input structure of the node, have add the tables to it. I've bound this input structure to the FM2 node.

When I execute the FM2 these table rows are appended to the existing FM2 tables. I actually need just the values to be copied to the input tables.


Node ZABC - OUTPUT - A,B tables (sub nodes)


Node ZXYZ INPUT - X, Y tables (sub nodes)

Structures X1, Y1 of type X and Y respectively

Structure ZXYZ1 of type ZXYZ

Copied values from Output of ZABC A and B into X1 and Y1.




Executed FM ZXYZ

Version: NWDS 2.0

Netweaver 2004s SP15

Thank you,

    Hi Vasu,

    It seems you get the results but the older data is still there & you need to clear that data.

    You can invalidate the context like wdContext.nodeOutput().invalidate() (you can call this code at time of execute statement)

    Kind Regards,

    You can use the methods WDCopyService

    Example : WDCopyService.copyElements(source, target)

      May be you can fetch the data from the table with looping the table size and catching the

      index of the elements . To be more clear .

      1 . get the size of the table .

      int leadSelection= wdcontext.node<TableName>.getLeadSelection();

      for (int i=0 ;i<n;i++)




      String name = wdcontext.node<tablename>.getelementatindex(leadSelection).getname();

      similarly fetch the size of the other elements from the table .

      and set to other RFC as

      ZClass abc = new ZClass();



      and othere thing is when you use Abstract class you can insert only one element at a time .

      or may be you may want to set the values direclty to the RFC

      AbstractList lst = new ZClass.ZClassList();

      ZClass cls = new ZClass();





      execute the RFC .

    you need to make loop with you first node size and get the values from first node, and set the values to second node.

    you need to create the elements for both the nodes and get and set the values based on the condition, by using the loop you can get the value of every field.

    like wdContext.node<nodename>.get<nodename>Elementat(i). - to get the record at " ith " position.

    wdContext.node<nodename>.get<nodename>Elementat(i).get<attributename>(); to get the value of a field at a specific position from a record.

    after getting the values from the first node you can set that to second node right

    may be it can help you,

      I've declared abstract lists of type (FM tables). I've added rows to this lists and set this lists to the function module nodes. This way, news rows are not added and the problem is resolved.

      In the example I mentioned.

      FM2 - ZXYZ

      Node ZXYZ INPUT - X, Y tables (sub nodes)

      Abstractlist of type input tables (X,Y) in the model



      Executed FM ZXYZ

      Thank you,
