Problems to get the content of context to R/3

[Former Member]

Hello,

i have problems with connection between the context in web dynpro and r/3. I use a rfc function, which i wrote on my own (no standard) in order to get persons from web dynpro to r/3. In web dynpro I created a multi selection table where the user can choose a list of persons. the selection works in web dynpro. for example: when i choose two persons then i can see those two persons in my context (model node) but not in the table of the rfc function in r/3. that's my problem. here some coding of my view implementation.

		
for (int i = 0; i < wdContext.nodeBearbeiter().size(); i++) {
  if (wdContext.nodeBearbeiter().isMultiSelected(i)) {
    String str = wdContext
                 .nodeBearbeiter()
                 .getElementAt(i) 
                 .getAttributeValue("Bname")
                 .toString();
				
    Usr03 bearb = new Usr03();
				
    IWDNodeElement fb_bearb = 
                     wdContext
                     .nodeZ_Fh0002_Datenverwaltung()
                     .nodeImt_Bearbeiter()
                     .createImt_BearbeiterElement(bearb);

     fb_bearb.setAttributeValue("Bname", str);
				
     wdContext.nodeZ_Fh0002_Datenverwaltung()
              .nodeImt_Bearbeiter()
              .addElement(fb_bearb);
  }
}

the node z_fh0002_datenverwaltung is mapped to the controller context. the mapping between view and controller works. in the example: I can also see those two selected persons in the context node of the controller context just before calling the r/3 function. but the table imt_bearbeiter() is always empty in r/3.

can anybody help me please?

best regards

Hi

I think if every thing is correct

u need to write this piece of code.

u have written

wdContext.nodeBearbeiter().getElementAt(i).getAttributeValue("Bname").toString();

whereas i feel u shuld write like this

wdContext.nodeBearbeiter().getBearbeiterElementAt(i).getAttributeValue("Bname").toString();

Just Check This

hello,

thanks for your answer but it doesn't help. I already have the same problem.

Can you post the code that calls the R/3 function module?

Apart from that, you could use the typed context API for accessing the attribute value.

Hello Armin,

here my coding for calling the r/3 function:

<u>view controller</u>

wdThis.wdGetAccountCreateController().callZ_Fh0002_Datenverwaltung();

<u>component controller</u>

wdContext.currentZ_Fh0002_Datenverwaltung_InputElement()
         .modelObject()
         .execute();

wdContext.nodeZ_Fh0002_Datenverwaltung_Input()
	 .nodeOutput()
	 .invalidate();

What do you mean with the typed context API?

Your code seems correct.

Where do you set the values to be inserted into the RFC in the view or in the component controller?

I would like to know how you have mapped the nodes also.

Hi,

the values I set in context of the view and this is mapped to the component controller context. I report some messages (IWDMessageManager) to check my coding in the component controller just before calling my rfc function and I detected that the correct values also in the context of the component controller. but if i debugg to r/3 there are the tables empty.

Z<RFC>_input inp=new Z<RFC>_input();

wdContext.node<nodename>().bind(inp);

for(){

<Table> tab=new <Table>

tab.set<value>();

inp.add<table>(tab);

}

This is how we set the tables in to RFC.

Try changing your code.

Rest everything seems perfect

Hello,

that I did one view before. When I did it again do I not initialize my context?

Regards

You need not re initialize.

Instead of

Z<RFC>_input inp=new Z<RFC>_input();

you can give the following

Z<RFC>_input inp=wdContext.currentZ<RFC>_inputelement.modelObject();

now set the table as I said above. I think it is the problem with the way you set the table.

Would you mind providing the ABAP code where you enter the values from the table into the database table?

try the following

for (int i = 0; i < wdContext.nodeBearbeiter().size(); i++) {

if (wdContext.nodeBearbeiter().isMultiSelected(i)) {

String str = wdContext

.nodeBearbeiter()

.getElementAt(i)

.getAttributeValue("Bname")

.toString();

Usr03 bearb = new Usr03();

wdContext.nodeImt_Bearbeiter().addElement(bearb);

bearb.setAttributeValue("Bname", str);

}

}
