This error can occur due to many reasons.Few of them could be:

1.Bapi might not be imported properly

2.A new structure or parameter might have been added and the bapi might have been not reimported.

If it is not due to above reasons then try deleting the model and create a new rfc model

Hi,

Have you given all the madatory inputs to the request object and executing the model.

If you are giving all the mandatory inputs and executing the model then check there might be some problem with bapi execution.

And print the exception by keeping the statements in exception block

e.getMessage()

e.getCause()

Hi,

In the catch block of model execution code.

try

{

wdContext.currentZentity_Mstr_InputElement().modelObject().execute();

}

catch(Exception e)

{

wdComponentAPI.getMessageManager().reportException("Error Message "+e.getMessage,true);

wdComponentAPI.getMessageManager().reportException("Error Cause "+e.getCause,true);

}

Hi,

Hi viswa,

You are not passing the mandatory fields ZCOUNTRY and ZENTITY_MSTR to the bapi

please try to set some empty string or some default value in these fields and execute the model.

Hope this helps you in resolving the problem

Hi,

You need to create the object for the proxy class ZENTITY_MSTR and set the value for COUNTRY field

try
{

Zentity_Mstr_Input objZentity_Mstr_Input=new Zentity_Mstr_Input();

//Create the object for proxy class ZENTITY_MSTR
ZENTITY_MSTR objZENTITY_MSTR=new ZENTITY_MSTR();

//Set the country value
objZENTITY_MSTR.setZCountry("Country");

objZentity_Mstr_Input.set/addZENTITY_MSTR(objZENTITY_MSTR);

wdContext.nodeZentity_Mstr_Input().bind(objZentity_Mstr_Input);

wdContext.currentZentity_Mstr_InputElement().modelObject().execute();
}
catch(Exception e)
{
wdComponentAPI.getMessageManager().reportException("Error Message "+e.getMessage,true);
wdComponentAPI.getMessageManager().reportException("Error Cause "+e.getCause,true);

}

Hi,

I have not created the BAPI ,

I am using the function module directly....

there is no errors in function module....it's working perfectly....

But I am getting the error as

Error Message Mandatory parameter ZCOUNTRY of method ZENTITY_MSTR missing

Error Cause com.sap.aii.proxy.framework.core.DataAccessException: Mandatory parameter ZCOUNTRY of method ZENTITY_MSTR missing

Can anyone help me in this,....

Hi,

While executing Fuction Module in WebDynpor for Java you are getting this right?

This is because you are not passing the input for ZCountry field while executing from WebDynpo.

So you need to pass that value.

Hi,

In ABAP workbench check transaction ST22 for any errors for BAPI/RFC side.

If there are no errors from BAPI side, check from your code side by setting external breakpoint in BAPI

Hi viswa,

Print the exception and exception cause in catch block to know the exception detail.
