I am developing a project using Dynpros,scenario is like this there is a login view it take ENo and password as input then navigate to Item view in this view i used Link to action UI elements, corresponding to each link action element trigger one view let's say mydata view bankdetails view etc.. for each of these views i am accessing bapi (backend data). I got bapi data for the first viwe (on display), for the second view i am not getting data from Bapi eventhough i mapped it correctly.. what may be the reason?(Urgent)

Are you doing an invalidate of the node bound to the table after the execute call

Yes I am doing Invalidate of the node after the excution call

public void excuteYzBapiAddressempInput( )

{

//@@begin excuteYzBapiAddressempInput()

try{

wdContext.currentBapi_Persdata_Getdetailedlist_InputElement().modelObject().execute();

}catch(Exception ex){

ex.printStackTrace();

}

wdContext.nodeOutput().invalidate();

//@@end

}

Hi Ramakrishna,

Just a guess but since you said that you are having many BAPI's for each view <b>nodeOutput</b> may not belong to the Model class that is related to the BAPI. Remember that you have to change the names of nodes incase there is a duplication of nodes. And output node is there in all the Models.

So can you pls verify that you are checking the correct output node for data.

Hi Sidharth,

I Have One View for one Bapi, yes as you said there is a possiblity of node duplication,i took care about this by giving different name Example:Bapiname_Input in this nodeOutputB (insteadof nodeOutput).

Hi Ramakrishna,

Yes but in the code sample above you had validated nodeOutput and not nodeOutputB.

Hence i thought whether you were accessing correct node or not.
