Hi,

You can use collections in java.util package and using this u can pass structures.

Is this wat u want?

If yes ...go to parameters of method and select a java native type java.util.* ..whatever chooses ur requirement?

IF this does not suit u requirement ,please elobarate the scenario..

If you need to pass table or structure to RFC or BAPI refer the following link

if u want to pass a table to a method, one way of achieving it is thru a LinkedHashMap.

Give the type of the parameter as LinkedHashMap

private LinkedHashMap map = new LinkedHashMap(linkedHashSize);

int hashKeyInt = 1;

for(loop thru the table)

{

<Table Class> tableObj = new <Table Class>;

tableObj .set<attribute1>(<value>);

.

.

map.put(String.valueOf(hashKeyInt), tableObj);

hashKeyInt++;

}

When calling the method, pass 'map' as the parameter.

<method>(map);

At the other end(inside the called method), the values can be retrieved thru an Iterator.

Iterator iteratorHashMap = map.values().iterator();

while (iteratorHashMap.hasNext() == true)

{

<Table Class> = (<Table Class>)iteratorHashMap.next();

}

Ok,

So let assum that I'm in my <b>view</b> and got this code:

Bapif4B bapiSelection = new Bapif4B();

ArrayList selection=new ArrayList();

for ...{

bapiSelection.setSelect_Fld(<Value1>)

bapiSelection.setLow(<Value2>);

bapiSelection.setSign("I");

bapiSelection.setOption("EQ");

selection.add(bapiSelection);

}

Now in My controller I got a method that accept parameter of type ArrayList.

public void getValWithSelection( java.util.ArrayList <b>selection</b> )

{

//@@begin getValWithSelection()

Bapi_Helpvalues_Get_Input input = new Bapi_Helpvalues_Get_Input();

wdContext.nodeBapi_Get_Shlp_Val_input().bind(input);

now what I'm doing with the parameter <b>selection</b>?

I want to pass the parameter <b>selection</b> to input.addSelection_For_Helpvalues().

Hope that's clear

Thank you

Hi Joseph,

What is the type of your parameter in input.addSelection_For_Helpvalues()?

Is it requires Abstractlist or any structure?

Let me know.

for(loop thru the arraylist until arraylist.size())

{

Bapif4B obj = (Bapif4B)arraylist.get(index);

input.addSelection_For_Helpvalues(obj);

}

Hope this helps

hi Bhavik,

input.addSelection_For_Helpvalues() required a structure Bapif4b.

Thank you

thank you it works...but...

when i add value to my array list and loop after on this list, i retreive only the last item... this is how i initialize the array list:

Bapif4B bapiSelection = new Bapif4B();

ArrayList selection=new ArrayList();

for...{

bapiSelection.setLow(valueToSearch);

bapiSelection.setSign("I");

bapiSelection.setOption("EQ");

selection.add(bapiSelection);

}

there is a problem?

I Think Bapi Selection shuld be instantiated inside the for loop

Hi Joseph,

Did you checked what is the size of the arraylist in for loop for retrieving values.

Make change in your code as follows:

ArrayList selection=new ArrayList();

for...{

Bapif4B bapiSelection = new Bapif4B();

bapiSelection.setLow(valueToSearch);

bapiSelection.setSign("I");

bapiSelection.setOption("EQ");

selection.add(bapiSelection);

}

initialize your object in the for loop.

Let me know.
