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.?

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

Thanks,

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.

Hi Prasana,

The body you are passing was not correct, call service using below body.

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

Accept: application/json

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

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

Accept: application/json

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

--batch--

Thanks,

Hi Arun,

I used the same body which u have mentioned above by changing my entity collection.

Now it gives an msg that "Response does not contain any data."

I checked the thread http://scn.sap.com/thread/3403864  and gave the same spacing suggested but still it gives this message.

Am i missing something here.

Hi Prasana,

This issue was because of spacing only, please try the spacing as shown below.

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

Accept: application/json

<<Only one Enter>>

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

<<Only two Enter>>

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

Accept: application/json

<<Only one Enter>>  

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

<<Only three enter>>

--batch--

Thanks,

Hi Arun,

Thanks you it worked .

But the issue is though i gave the filter query in the body its returning the entitycollection.

In my case country with 'AT' has 2 records and 'BE' has 3 records. So it should return me 5 records.

But its returning the entitycollection. Should we have to do a separate implementation for this??

Hello Sandhya,

Please correct the URL,

U need to pass the filters as below :

Sample Payload for ur reference -> Correct ur URL accordingly

--batch--

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

GET get_emp_dataSet?$filter=Userid+eq+'00001'+and+Name+eq+'ASH*' HTTP/1.1

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

GET get_emp_dataSet?$filter=Userid+eq+'00002' HTTP/1.1

--batch--
