Nested input tables

[Former Member]

Hi,

We´re having problems to call an RFM from Web Dynpro (version 2.0.15). Our input structure looks as follows:

Zaf_Afa_Ws_Sok_Input

L Filter - Structure

L Filter Item - Table

L Filter Key - Table

This is the code:

wdContext.nodeZaf_Afa_Ws_Sok_Input().bind( new Zaf_Afa_Ws_Sok_Input() );

Zafa_Wsrequest_Filter filter = new Zafa_Wsrequest_Filter();

Zafa_Wsrequest_Filteritem FNRFilterItem = new Zafa_Wsrequest_Filteritem();

Zafa_Wsrequest_Filterkey FNRFilterKey =new Zafa_Wsrequest_Filterkey();

FNRFilterKey.setValue( wdContext.nodeSearchAttributes().currentSearchAttributesElement().getFnr());

FNRFilterItem.setType("FNR");

FNRFilterItem.addFilterkey(FNRFilterKey);

// add item to filter

filter.addFilteritem( FNRFilterItem );

// bind filter to RFC

wdContext.nodeZaf_Afa_Ws_Sok_Input().nodeIs_Filter().bind( filter) ;

wdContext.nodeZaf_Afa_Ws_Sok_Input().currentZaf_Afa_Ws_Sok_InputElement().modelObject().execute();

---

When debugging the java code the model gets all the data, but when looking at the ABAP code all tables are "initial".

An idea anyone how to solve this?

Thanks,

Sophie,

Sadly, I cannot find anywhere document regarding Adaptive RFC Model "do-es" and "don't-s" but there was a strong point that nested tables must not be used.

Moreover, in our own project we found and reported a bug with tables as input parameter (instead of table parameter), that cause tables to break output structure handling (they were erroneously duplicated in output). I'm not sure whether or not this bug was fixed since last autumn '05.

So, in brief: don't use table parameters as import/export and do not use nested tables. Re-write your RFM or expose it via other RFM with simple structure.

Sophie,

you have to maintain your nested tables at the <b>modelObject</b> like this:

Zaf_Afa_Ws_Sok_Input myInput = wdContext.currentZaf_Afa_Ws_Sok_InputElement().modelObject();

//maybe you want to empty it, if existing
if (myInput.getFilterItem() != null) {
  myInput.getFilterItem().clear();
}

myInput.addFilterItem(FNRFilterItem);

Achim,

Thank you for your quick answer. However, I think I was a bit unclear in my description. The input structure should contain three levels:

Zaf_Afa_Ws_Sok_Input
  |_
     Filter (=structure)
     |_ 
        Filter Item (=table)
        |_ 
          Filter Key (=table)

Suggestions...?

Thanx,

Sophie
