Hi Raja,

If I understand the question correctly, the $batch is the only operation that you can use to send multiple requests over one http call.

It is possible to use the RFC methods, but the $batch function was introduce in SP4 (I believe) so if you were running SAP NetWeaver Gateway 2.0 SP3 as in the How-to guide example, it wouldn't work.

Hi Raja,

If you are using SUP ODP to consume Gateway REST services, here is some android saple code to send multiple request in single call. Please revert back if this is what you are looking for. I will share you the code to hadle the response as well.

ISDMBundleRequest batchRequests = new SDMBundleRequest();

String serviceDocPath = "http://<host>:port /sap/opu/sdata/iwfnd/RMTSAMPLEFLIGHT/";

ISDMRequest serviceDocRequest = buildRequest(serviceDocPath , (ISDMNetListener) this);

batchRequests.addRequest(serviceDocRequest);

ISDMRequest metaDataRequest = buildRequest(serviceDocPath + "$metadata",(ISDMNetListener) this);

batchRequests.addRequest(metaDataRequest);

searchURL = "http:// <host>:port/sap/opu/sdata/iwfnd/ RMTSAMPLEFLIGHT/carrierCollection";

ISDMRequest collectionDataRequest = buildRequest(searchURL, (ISDMNetListener)this);

batchRequests.addRequest(collectionDataRequest);

getRequestmanager().makeRequest(batchRequests);

Hi Brown,

Thanks for your information. if you see the link i have attached, it will show the service RMTSAMPLEFLIGHT is not build on modelling like BOR, RFC, etc and we are using the latest version of SAP Netweaver gateway.

Hi Raja,

If I understand your question correctly, You are trying to send batch requests to gateway.

Batch => Multiple operations in single call/requests.

The cample code I shared above is to send batch/bundle requests from android application to gateway using SUP.

SUP:- Sybase unwired platform which is a mobile platform ofering from SAP to develop online/offline mobile applications.

Is my undertsnading correct here?

Regards

Hi Rowtham,

"The server is refusing to process the request because the entity has a unsupported format" error usually occur when we provide invalid content Type .

Based on above post Content-type is fine even i tested it working properly as shown below

Its Content-Type: multipart/mixed; boundary=batch

Hi Gowtham,

Its all depends on ur entity design .

- we can use GetEntitySet Method if Barcode information is also presented in same entity with help of $filter option.

- If not available use custom operation http://www.odata.org/documentation/uri-conventions#ServiceOperationParameters .

- one more option is to use "select" option which is also implemented in GETEntityset . I think this option is provided by SAP not from Odata Protocol.

Hi,

Can multiple batching operations be used for $filter and $select operations as well... ?

Hi Arun,

Thanks a lot for the quick response. But in my case its always fetching the entity collection though i give the filter condition. The request body looks like below

-------------------------------------------------------------------------------------------------------------------------------------------------

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

Accept: application/xml

GET CUSTOMERCollection/?$filter = COUNTRY eq 'AT' HTTP/1.1

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

Accept: application/jsonxml

GET CUSTOMERCollection/?$filter = COUNTRY eq 'BE' HTTP/1.1

--batch--

---------------------------------------------------------------------------------------------------------------------------------------

Am i missing something here.

Even if i keep the debugger point the table it_filter_select_options is empty.

Could you please help me on this regard.?

arunchembra1 — Mon, 26 Aug 2013 11:40:24 GMT

Hi Prasana,

1. Instead of batch request call single request and check you are getting data for CUSTOMERCollection/?$filter = COUNTRY eq 'AT' HTTP/1.1 and CUSTOMERCollection/?$filter = COUNTRY eq 'BE' HTTP/1.1 .

2. While calling batch you are getting any erro?

3. Have you redefine/IWBEP/IF_MGW_APPL_SRV_RUNTIME~CHANGESET_BEGIN and

/IWBEP/IF_MGW_APPL_SRV_RUNTIME~CHANGESET_END methods. If not please refer this link http://scn.sap.com/docs/DOC-45504

4. Please check this link also http://scn.sap.com/thread/3403864

Hi Arun,

If i execute the requests separately its fetching the data.

Now i am geeting an error "Invalid type for '$filter' system query option. Expected type is 'Edm.Boolean'" when do a batch operation.

I have redefined both the changeset begin and change set end.

Prasanna.
