Solved: CM_NO_DATA_RECEIVED Errror ???????????????????

Hello Everyone,

I have developed a Web Dynpro application, which makes 3 BAPI calls.

2 of them work fine. However one of the BAPI is giving me the following error message -

connection closed without message (CM_NO_DATA_RECEIVED), error key: RFC_ERROR_COMMUNICATION

I guess, its not the JCO Problem. Is it ?

Am really surprised how come only One BAPI gets this error message.

Please help me figure this out.

Thanks and Regards,

Samta

Samta,

Can you paste me the code on how you are accessing the third RFC. Whats happening here is, either web dynpro application or R/3 is terminated in advance. You can also see it in ST05 transaction.

Paste your code here, I will look for it.

Hello Raj,

Thanks for your quick response.

The code that i have written in the Web Dynpro application is -

Or does it terminate before it reaches the BAPI, as the error message says communication error.</b>

Am stuck up really.

Please help.

Samta,

Please see my comments, unfortunately I dont understand much of your code, as its in a standard way. I have a working code, something similar, I can send you if u want.

Z_Mm_XX_Create_Ses_Input z_bapi = new Z_Mm_XX_Create_Ses_Input();

***Binding is missed.

You should set the values to the model object that u instantiated z_bapi

wdContext.currentV_UI_Header_DataElement().getV_UI_Portal_Id());

wdContext.currentZ_Mm_XX_Create_Ses_InputElement().setRelease_Flag("X");

wdContext.currentZ_Mm_XX_Create_Ses_InputElement().setCalltype("B");

is this how you execute the method?

***usually it should be wdContext.CurrentZ_Mm_XX_Create_Ses_Input().modelObject().Execute();

Hello Raj,

Thanks a lot for your quick response.

Really appreciate your patience.

This is the modified version of the code-

Still its giving me the same error

Samta,

Here is what I have from my purchase order application which is running successfully for last 2 months. Please observe it carefully, and try to understand. If u still have problem, I guess your are in US, I will try to resolve it.

Hi samta,

Please send the code inside executeZ_Mm_XX_Create_Ses_Input() method, we will see whether that part is ok - as thats the part where you are executing the RFC.

regards

Hello Raj/LM,

I have changed my code to this -

and i am just setting one node and printing it as a table in the view.

____________________________________________________

Z_Mm_Cmet_Create_Ses_Input z_bapi =

new Z_Mm_Cmet_Create_Ses_Input();

wdContext.nodeZ_Mm_Cmet_Create_Ses_Input().bind(z_bapi);

//Set the header

Zresm_Cmet_Header z_header = new Zresm_Cmet_Header();

z_header.setApprover(list_approver.getV_UI_ApproverName());

z_header.setShort_Text("sam");

z_header.setSheettype("4004");

z_header.setVendor("123456");

z_bapi.addTbl_Es_Header(z_header);

z_bapi.setPortal_Id("123456");

z_bapi.setRelease_Flag("X");

z_bapi.setCalltype("B");

wdThis.executeZ_Mm_Cmet_Create_Ses_Input();

_____________________________________________

Now when i print this model node in the view using apply template - > table i get the table as blank.

Why is the data not setting in the model node.

Am i missing on nything.

I c no issues with the model node properties.

And in the executeZ_Mm_Cmet_Create_Ses_Input() method i have the following piece of code -

__________________________________________________

IWDMessageManager manager = wdComponentAPI.getMessageManager();

try {

wdContext.currentZ_Mm_Cmet_Create_Ses_InputElement().modelObject().execute();

wdContext.nodeOutput().invalidate();

} catch (WDDynamicRFCExecuteException ce) {

manager.reportException(ce.getMessage(), false);

}

__________________________________________________

Please help.

Am really stuck up with this.

Thanks in advance.

Samta

Hi,

In your model binding, check whether you have done the following.

Click on Z_Mm_Cmet_Create_Ses_Input node, right click to say edit model binding. You should have clicked all the input parameters that you have given here, like short_text,sheettype etc. Then,click on output. Under here, you click all the output parameters that you expect(any tables or whatever).

Only then will the nodeOutput.invalidate work.

Regards,
