You can find this Function Group from function module (BAPI) itself. Go to transaction SE37 and enter function module name (BAPI name) and click on display. You can see the function group here under attribute tab .

2. Then from Function Modules list choose the BAPI to which you want to expose as a

Web Service .

3. On right clicking on the BAPI a context menu appears. Click on create and Web Service option .

4. New window will pop up. Click on Continue.

5. Give the name for Enterprise service and short description. Click on continue.

give a sap logon userid and password and store it as a wsdl extension.

Check your SAP logon userid validity with the BASIS team.

may be it will help you.

Hi Deepanker,

I have already expose the BAPI to Web Service. What the BAPI do is to create an employee detail.

The problem now is i enter the required field Employeenumber, and submit it it return an error:

============================================

An error has occurred. Maybe the request is not accepted by the server:

Deserialisation failed

Error accessing the ref. node 'EMPLOYEENUMBER'

============================================

Why is that so?

Regards,

Rayden

I am also having the same error with a custom function.

this is the trace from sm59

XRFC> ERROR 16:48:08: SOAP Message CL_SOAP_MESSAGE->IF_SOAP_MESSAGE <

XRFC> PART~DESERIALIZEBODY() SOAP Fault Exception caught: : <

XRFC> Deserialisation failed <

I have exposed other web services and i am able to execute those just fine. However, this WS fails. I am using the same user, same auths & i have no problems running the function module in r3.

I was able to fix my issue.

I was passing the date incorrectly. Originally I passed the date as "20080501", the WS wanted the date passed "2008-05-01".

Hello Daniel,

How we can make use of the WSDL file for calling the Webservice from outside the SAP system? I have a RFC FM pointed to a service definition and I have the WSDL file with me.

Can you please guide me how I can make use of this WSDL for the Webservice call?

Thanks for your help in advance.

Thanks,

Greetson
