Displaying Bapi Return message in View (Urgent !)

[Former Member]

Hi

I Have a Bapi which doesn't have any data but there are some return messages.

How to display these return messages in a webdynpro view

is there any tutorial or code so that i can get the return messages from Bapi and display in Bapi

I already mapped bapi to custom controller and then custom controller to View.

in customer controller i am excuting this bapi and i am calling this bapis method in views on action Go button, but i need to display all the return messages.

com.sap.package4.Bapireturn ret1 = input1.getOutput().getReturn();

String var1 = ret1.getMessage();

msgMgr1.reportSuccess(var1);

after excution i am getting null pointer exception

is there any solution..

Regards,

Murali

Hi Murali:

Have you solved this problem? I've got the same problem with you. I can get the output value from the BAPI, but can't get the return value.

If you know why, can you let me known? Thanks a million!

Hi Murli,

Write following code for dispalying Return message.

String message = wdcontext.currentReturnElement().getMessage();

msgMgr1.reportSuccess(message);

Here, Return is your node in which you are getting your return message.

If it still gives null pointer exception then put this code inside following if statement.

if(wdcontext.currentReturnElement() != null)

{

}

Murali,

Open layout tab of the view. Right click on "Root UI Cotainer" select "Apply template" Select table, Click 'Next'. Select the bapi return Node.

After the execution of Bapi, u would see the complete return structure in a view.
