Control not going to backend

[Former Member]

I created a custom controller and wrote the following code in the init part of Cust controller. No errors. But when i deploy control doesnt goto the back end and in the view empty table is coming up.

Requirement is to pass the userid to the backend and get the data from the BAPI and siaplay it in the table format.

input1.setUserid("USRID");

wdContext.nodeZ_Ess_Read_9099_Input().bind(input1);

try {

input1.execute();

wdContext.nodeOutput().invalidate();

} catch (Exception Ex) {

Ex.printStackTrace();

}

//@@begin others

Z_Ess_Read_9099_Input input1;

//@@end

Dear Pankaj,

Have you tried executing the Bapi from the ecc system i.e. using SAP Logon?

If not try that and check whether you get an output for the userid you provide as input?

I think the problem is that no data exists for the userid you provided. Or some other input must be required along with the userid.

Because your code looks fine.

If the Bapi executes fine in the ecc system,

then check the message returned in the "return node" when you execute from web dynpro. Bind it to a table and check.

Convey the results here.

Regards,

Mayuresh.

Hi,

Try to print a message using message manager to see the code is executed as expected.

Have you invalidated the context after execution?
