Can we make a BDC program as a webservice

Former Member · ‎11-07-2011

Hi All,

Can we write a BDC program in RFC Function Module and access it through web service.

We have a requirement to create a Return Order, for that we have recorded the Va01 transaction for return order and included the same recorded code in RFC Function module and also created web service for it. But when we tried to access through webservice, it is showing the following error

"Call to returned http code 500 (Internal Server Error) with unacceptable content type (text/html; charset=utf-8).

><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><soap:Fault><faultcode> soap:Server </faultcode><faultstring xml:lang="en"> RABAX occurred on server side </faultstring><detail><sap:Rabax xmlns:sap="http://www.sap.com/webas/710/soap/runtime/abap/fault/generic"><MESSAGE>Access via 'NULL' object reference not possible.</MESSAGE><SYMSGID>VX</SYMSGID><SYMSGTY>S</SYMSGTY><SYMSGNO>206</SYMSGNO><SYMSGV1>TextEditControl</SYMSGV1><SYMSGV2></SYMSGV2><SYMSGV3></SYMSGV3><SYMSGV4></SYMSGV4><SYREPID>SAPLV70T</SYREPID><SYTCODE>VA01</SYTCODE><SYDYNNR>2000</SYDYNNR><SYUNAME>DIK</SYUNAME><SYMANDT>100</SYMANDT><SYLANGU>E</SYLANGU><SYECODE>558</SYECODE><SYHOST>sapdvp</SYHOST><SYSYSID>SD1</SYSYSID><SYOPSYS>Windows NT</SYOPSYS><SYDBSYS>MSSQL</SYDBSYS><SYSAPRL>700</SYSAPRL><SYXPROG>SAPCNVE</SYXPROG><SYXFORM>CONVERSION_EXIT</SYXFORM><SYDATUM>20111104</SYDATUM><SYUZEIT>153001</SYUZEIT><SYETEXT>RABAX_STATE</SYETEXT><ERRORCODE>OBJECTS_OBJREF_NOT_ASSIGNED</ERRORCODE><PATHTRANS>/sap/bc/srt/rfc/sap/zcom_create_return_bdc/100/zcom_create_return_bdc/zcom_create_return_bdc</PATHTRANS><MESSAGE>Access via 'NULL' object reference not possible.</MESSAGE><ERRORCODE>OBJECTS_OBJREF_NOT_ASSIGNED</ERRORCODE></sap:Rabax></detail></soap:Fault></soap:Body></soap:Envelope>"

When we execute the same RFC from SAP SE37 T-Code , it is working fine but same not working from web service .

One more thing If anybody knows the standard BAPI or Function Module to create the Sales Return Order please do post .

Thanks in advance ,

Hi Chaitanya,

For the first problem - objects not assigned, refer the following link:

Link: [;

I feel you are missing some parameter in your connection string. Your BASIS Team should help you to resolve this issue.

For the second problem - BAPI for Sales Order Return, even I would recommend you to use a BAPI instead of a BDC. Since, you are using T. Code VA01, I believe 'BAPI_SALESORDER_CREATE' should be the right one. I'm not sure about the BAPI as I have never worked on that scenario.

Hi Pranav,

created rfc function module in sap using se37 t-code for sales return order and i am using bdc performs in it to create return order with reference order and it is working fine when we testing in sap, but when we run the same rfc function module

through webservices it giving the below error

(Call to returned http code 500 (Internal Server Error) with unacceptable content type (text/html; charset=utf-8).

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><soap:Fault><faultcode> soap:Server </faultcode><faultstring xml:lang="en"> RABAX occurred on server side </faultstring><detail><sap:Rabax xmlns:sap="http://www.sap.com/webas/710/soap/runtime/abap/fault/generic"><MESSAGE>Access via 'NULL' object reference not possible.</MESSAGE><SYMSGID>VX</SYMSGID><SYMSGTY>S</SYMSGTY><SYMSGNO>206</SYMSGNO><SYMSGV1>TextEditControl</SYMSGV1><SYMSGV2></SYMSGV2><SYMSGV3></SYMSGV3><SYMSGV4></SYMSGV4><SYREPID>SAPLV70T</SYREPID><SYTCODE>VA01</SYTCODE><SYDYNNR>2000</SYDYNNR><SYUNAME>DIK</SYUNAME><SYMANDT>100</SYMANDT><SYLANGU>E</SYLANGU><SYECODE>558</SYECODE><SYHOST>sapdvp</SYHOST><SYSYSID>SD1</SYSYSID><SYOPSYS>Windows NT</SYOPSYS><SYDBSYS>MSSQL</SYDBSYS><SYSAPRL>700</SYSAPRL><SYXPROG>SAPCNVE</SYXPROG><SYXFORM>CONVERSION_EXIT</SYXFORM><SYDATUM>20111109</SYDATUM><SYUZEIT>105717</SYUZEIT><SYETEXT>RABAX_STATE</SYETEXT><ERRORCODE>OBJECTS_OBJREF_NOT_ASSIGNED</ERRORCODE><PATHTRANS>/sap/bc/srt/rfc/sap/zrfc/100/zrfc/zrfc</PATHTRANS><MESSAGE>Access via 'NULL' object reference not possible.</MESSAGE><ERRORCODE>OBJECTS_OBJREF_NOT_ASSIGNED</ERRORCODE></sap:Rabax></detail></soap:Fault></soap:Body></soap:Envelope>).

i am dubuged that function module , it is giving error in call transaction perform in bdccode. remaining performs are working fine so just give help me how to solve that type of errors in webservice.

what does meaning of " Access via 'NULL' object reference not possible.</MESSAGE><ERRORCODE>OBJECTS_OBJREF_NOT_ASSIGNED</ERRORCODE></sap:Rabax></detail></soap:Fault></soap:Body></soap:Envelope>)".

Hi Chaitanya,

The error you have mentioned is referring to calling of a screen in RFC. As the webservice cannot access the screens of a BDC in RFC mode, your code needs to run in background mode for the RFC to process.

Also, I suppose there is a confusion in BDC and FM. If you are using a BAPI/FM, then the need for a BDC should not be there as both perform the same function. Hence, perform BDC should not be part of the code.

If I've misinterpreted the details, then, please post your FM and BDC code for further clarification.

Regards,

Pranav.

Hi Pranav,

Okay. Kindly let me know how to run rfc function module in background because we have call transaction perform in RFC function module and I am posting BDC code that is using inside RFC function module.
