Hello Hussain,

For now just redefine the ChangeSet_End and Begin Methods and write 'EXIT' statement and activate the class. Do not write any code.

Payload should have correct spacing. Use the below Payload and check ->

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

--changeset
Content-Type: application/http
Content-Transfer-Encoding: binary

POST headerSet HTTP/1.1
Content-Type: application/atom+xml
Content-Length: 1400

Hi Ashwin,

From Ui ,i am trying to do a mass data creation.If i am trying to create 10 item and out of which one of the item fails,i want to have a response back saying ,which all were sucessful and which resulted in error.How this can be achieved .I tried sending each create in separate changeset and even in case of error ,i get individual response.Is this the correct approch,to send ecah create in a separate changeset?Could you please help me here.

Thanks and Regards

Hello Neeta,

Please check the section ' Handling Operations in Batch Requests ' and try this approach ->

Call the Data Provider Class in Defer Mode :

$batch Processing - SAP NetWeaver Gateway - SAP Library

This way you can perform Create operation for all 10 items in one go and capture the success/error messages as part of GW response.

Hi Ashwin,

Thanks a lot for the link.Its really helpful.

Could you please let me know how to call a batch in defer mode?ie If i have test in in ethe gateway_client a sample request ,how to set the defer mode so that change_process method gets triggered.

Thanks and Regards

Neeta

Hello Neeta,

I do not have a working example to show but i can share the DPC name which has a demo case implemented for this approach.

Please have a look at the below class -> This has all details and helps you to implement

Class - /IWBEP/CL_MGW_RT_SFLIGHT

Methods -

/IWBEP/IF_MGW_APPL_SRV_RUNTIME~CHANGESET_BEGIN

/IWBEP/IF_MGW_APPL_SRV_RUNTIME~CHANGESET_END

/IWBEP/IF_MGW_APPL_SRV_RUNTIME~CHANGESET_PROCESS

Hi Ashwin ,

Thanksfor your quick response .What i am looking for is the request xml ,which will identify a batch request as deferred.Normally when i send a batch request ,it will not trigger the change set_process.So if this method needs to be triggered, what change should i make in the response xml?

Thanks and Regards

Neeta

[AshwinDutt]

Hello Neeta,

As far as i know there nothing to be added in the request payload for this. Payload would remain same if DPC is called in defer mode or not in defer mode.

Ashwin
